Abstract:
Актуальность исследований по изучение особенностей плодоношения группы орехоплодных связана с возрастающим спросом на их плоды и сокращением площадей естественного произрастания этих растений. Представители рода Corylus L. относятся к экономически важным растениям. Анализ литературных источников по опыту интродукции видов рода CorylusL. в разных пунктах России, позволил установить лимитирующие факторы для произрастания. В южных областях, развитие растений C. avellana (л. обыкновенной), C. heterophylla (л. разнолистной) лимитируют высокие летние температуры и дефицит влаги. В северных областях на рост и развитие C. pontica (л. понтийской), C. colurna (л. древовидной) влияют низкие зимние температуры (ниже –30°C). Приведены сведения о современном ареале Corylus avellana и сырьевом запасе плодов всех видов Corylus. Цель – провести анализ географии распространения представителей рода Corylus L. и их сезонные феноклиматические закономерности плодоношения. В естественной дендрофлоре Волгоградской области виды рода Corylus L. не произрастают, однако представляют научный и практический интерес работы по их интродукции. Получены экспериментальные материалы по плодоношению видового и сортового разнообразия рода Corylus L., которое произрастает в дендроколлекциях ФНЦ агроэкологии РАН, в условиях каштановых (кадастровый № 34:36:0000:14:0178), светло-каштановых почв (№34:34:000000:122; №34:34:060061:10), южных черноземов (Новоаннинский район, Волгоградской области). Дана сравнительная оценка жизненных форм и состояния Corylus L. в естественном ареале и районе исследований (Волгоградская область). Приведена динамика основных фенологических времен года в различных природных зонах РФ, где находится естественный ареал видов лещин. Установлена сопряженность фенофаз с сезонной ритмикой климатических параметров и наиболее важных фенофаз друг с другом. Выявлены пространственно-географические, разногодично-временные фенологические закономерности развития для прогнозирования реализации потенциальной плодовой продуктивности видов и сортов орехоплодных кустарников. The relevance of current research studies on characteristics of fruiting groups of nut-bearing associated with the increasing demand for their fruits and reducing the area of natural growth of these plants. Members of the genus CorylusL. are economically important plants. Analysis of the literature on the experience of the introduction of species of the genus Corylus L. in different parts of Russia, allowed to establish limiting factors for growth. In southern regions, plant development C. avellana, C. heterophyllous limit high summer temperatures and deficiency of moisture. In the Northern regions, the growth and development of C. pontica, C. colurna is influenced by low winter temperatures (below -30°C). The data on the modern area of Corylus avellana and raw stock of fruits of all Corylus species are given. The goal is to analyze the geographical distribution of the genus CorylusL. proclamations and their seasonal patterns of fruiting. In the natural dendroflora of the Volgograd region species of the genus Corylus L. do not grow, but are of scientific and practical interest to work on their introduction. Experimental data on fruiting species and varietal diversity of the genus Corylus L., which grows in the dendrocollections of the FNC Agroecology RAS, in chestnut (cadastre № 34:36:0000:14:0178), light-chestnut soils (№34:34:000000:122; №34:34:060061:10), southern humus (Novoanninskiy district of the Volgograd region). A comparative assessment of life forms and state of Corylus L. in the natural habitat and research area (Volgograd region) is given. The dynamics of the main phenological seasons in different natural zones of the Russian Federation, where the natural range of species of hazel is. The conjugacy of phenophases with seasonal rhythm of climatic parameters and the most important phenophases with each other is established. Spatially-geographical, interannual temporal phenological patterns of development to predict the potential fruit productivity of the species and varieties of nut-bearing shrubs.

Abstract:
Three microsatellite-enriched libraries of the european hazelnut (Corylus avellana L.) were constructed: library A for CA repeats, library B for GA repeats, and library C for GAA repeats. Twenty-five primer pairs amplified easy-to-score single loci and were used to investigate polymorphism among 20 C. avellana genotypes and to evaluate cross-species amplification in seven Corylus L. species. Microsatellite alleles were estimated by fluorescent capillary electrophoresis fragment sizing. The number of alleles per locus ranged from 2 to 12 (average = 7.16) in C. avellana and from 5 to 22 overall (average = 13.32). With the exception of CAC-B110, di-nucleotide SSRs were characterized by a relatively large number of alleles per locus (≥5), high average observed and expected heterozygosity (Ho and He > 0.6), and a high mean polymorphic information content (PIC ≥ 0.6) in C. avellana. In contrast, tri-nucleotide microsatellites were more homozygous (Ho = 0.4 on average) and less informative than di-nucleotide simple sequence repeats (SSRs) as indicated by a lower mean number of alleles per locus (4.5), He (0.59), and PIC (0.54). Cross-species amplification in Corylus was demonstrated. These microsatellite markers were highly heterozygous and polymorphic and differentiated among genotypes of C. avellana irrespective of geographical origin. They will aid in fingerprinting genotypes of the european hazelnut and other Corylus species, genome mapping, and genetic diversity assessments.

Abstract:
Understanding species-specific responses to climate change allows a better assessment of the possible impact of global warming on forest growth. We studied the responses of the shrub species Corylus avellana L., Corylus maxima Mill. and intermediate forms, together stated as the Corylus taxa, and Cornus sanguinea L. upon periodically elevated temperatures in spring and/or in summer–autumn. Experiments were performed in a common garden, with Belgian and Pyrenean provenances for Corylus avellana and Cornus sanguinea. In the Corylus taxa, a warmer spring resulted in a reduction in height and diameter growth. Remarkably, the reduced diameter increment was restored with full compensation in the following year. The height increment for Cornus sanguinea was larger upon a warmer summer–autumn, concurring with a later leaf senescence. Our results suggest that Corylus is more sensitive to spring warming, influencing growth negatively, whereas Cornus is more sensitive to summer–autumn warming, influencing height growth positively. These deviating responses can be explained, at least partly, by their diverging ecological niches, with the Corylus taxa being more shade-tolerant compared to Cornus sanguinea. The warm spring conditions advanced bud burst in all studied taxa, whereas the warm summer–autumn advanced leaf senescence but prolonged its duration in the Corylus taxa, as well as delayed this phenophase in Cornus sanguinea. Little to no after-effects of the temperature treatments were detected. Although Corylus avellana and Cornus sanguinea plants originated from similar origins, their growth and phenological responses in the common garden diverged, with Corylus being more stable and Cornus displaying more variation between the Belgian and Pyrenean provenances.

Abstract:
Показана актуальность изучения экологической пластичности древесных растений в связи с необходимостью подбора адаптированного видового состава деревьев и кустарников для защитных лесных насаждений в условиях климатических изменений. Установлено, что экологическая пластичность и пределы толерантности растений связаны со свойством организмов адаптироваться к тому или иному диапазону факторов среды. В статье представлен таксономический состав орехоплодных культур коллекций ФНЦ агроэкологии РАН. Это шесть видов рода Juglans: J. regia, J. mandshurica, J. cinerea, J. rupestris, J. ailanthifolia, J. nigra и три вида рода Corylus: С. avellana L., С. аmericana W., сорта С. pontica C. Koch Президент, Футкурами, Черкесский2. Приведены сведения о положительном опыте культивирования Corylus avellana L. в плантационных насаждениях (1,6 га, посадка рядовая, схема размещения 55 м) в условиях южных черноземов. Цель исследований изучить экологическую пластичность орехоплодных кустарников коллекций ФНЦ агроэкологии РАН. На примере родового комплекса Corylus получены материалы по экологической пластичности орехоплодных кустарников в условиях каштановых (кадастр. 34:36:0000:14:0178), светлокаштановых почв (34:34:000000:122 34:34:060061:10). Установлены уровни изменчивости морфологических признаков ассимиляционного аппарата и плодов С. avellana L., сортов С. pontica C. Koch., которые согласуются с зимо и засухоустойчивостью. Кластерный анализ позволил выявить корреляцию признаков при 5 уровне значимости. Для целей защитного лесоразведения и озеленения засушливых районов рекомендованы Corylus avellana и Черкесский2 с выраженной вариабельностью морфологических признаков, которая указывает на их широкую экологическую валентность и адаптационные возможности в рассматриваемых условиях. The urgency of studying the ecological plasticity of woody plants in connection with the need to select an adapted species composition of trees and shrubs for protective forest plantations in the context of climate change is shown. It is established that the ecological plasticity and tolerance range of plants is associated with the ability of organisms to adapt to a particular range of environmental factors. The article presents the taxonomic composition of nut crops in the collections of FSC Agroecology RAS. Six species of Juglans: J. regia, J. mandshurica, J. cinerea, J. rupestris, J. ailanthifolia, J. nigra and three species of the genus Corylus: С. avellana L., С. аmericana W., varieties of C. pontica C. Koch the President, Futkurami, Circassian2. Data on positive experience of cultivation of Corylus avellana L. in plantation plantings (1,6 hectares, landing ordinary, the scheme of placement of 55 m) in the conditions of southern chernozems are given. The purpose of the research is to study the ecological plasticity of nutbearing shrubs of the collections of the Federal scientific center for Agroecology Russian Academy of Sciences. For example, a generic complex Corylus submissions received on the environmental plasticity of nut bushes in the conditions of brown (the cadaster nubmer 34:36:0000:14:0178), light chestnut soils (34:34:000000:122 34:34:060061:10). The levels of variability of morphological features of the assimilation apparatus and fruits of Corylus avellana L., С. pontica C. Koch varieties were established., which are consistent with winter and drought resistance. Cluster analysis revealed the correlation of features at 5 significance level. Corylus avellana and Circassian2 with a pronounced variability of morphological features, which indicates their broad ecological valence and adaptation capabilities in the conditions under consideration, are recommended for the purposes of protective afforestation and greening of dry areas.

Abstract:
Thirty-eight bacterial strains isolated from hazelnut (Corylus avellana) cv. Tonda Gentile delle Langhe showing a twig dieback in Piedmont and Sardinia, Italy, were studied by a polyphasic approach. All strains were assessed by fatty acids analysis and repetitive sequence-based polymerase chain reaction (PCR) fingerprinting using BOX and ERIC primer sets. Representative strains also were assessed by sequencing the 16S rDNA and hrpL genes, determining the presence of the syrB gene, testing their biochemical and nutritional characteristics, and determining their pathogenicity to hazelnut and other plants species or plant organs. Moreover, they were compared with reference strains of other phytopathogenic pseudomonads. The strains from hazelnut belong to Pseudomonas syringae (sensu latu), LOPAT group Ia. Both fatty acids and repetitive-sequence-based PCR clearly discriminate such strains from other Pseudomonas spp., including P. avellanae and other P. syringae pathovars as well as P. syringae pv. syringae strains from hazelnut. Also, the sequencing of 16S rDNA and hrpL genes differentiated them from P. avellanae and from P. syringae pv. syringae. They did not possess the syrB gene. Some nutritional tests also differentiated them from related P. syringae pathovars. Upon artificial inoculation, these strains incited severe twig diebacks only on hazelnut. Our results justify the creation of a new pathovar because the strains from hazelnut constitute a homogeneous group and a discrete phenon. The name of P. syringae pv. coryli is proposed and criteria for routine identification are presented.

Abstract:
Eight Corylus L. (hazelnut) species were intercrossed in all possible combinations to reveal genetic relationships. Pollinations were made on either individually bagged branches or trees covered entirely with polyethylene using mixtures of pollen of five genotypes to minimize low cluster set due to single incompatible combinations. Percent cluster set, seed germination, and hybrid seedling survival were determined. Hybridity of seedlings was verified by inspection of morphological traits. Based on percent cluster set, seed germination, and hybrid seedling survival along with observed morphological similarities, Corylus species were placed in three groups: 1) the tree hazels C. colurna L. (turkish tree hazel) and C. chinensis Franchet (chinese tree hazel), 2) the bristle-husked shrub species C. cornuta Marshall (beaked hazel), C. californica (A.DC.) Rose (california hazel), and C. sieboldiana Blume (manchurian hazel), and 3) the leafy-husked shrub species C. avellana L. (european hazel), C. americana Marshall (american hazel), C. heterophylla Fischer (siberian hazel), and C. heterophylla Fischer var. sutchuensis Franchet (sichuan hazel). The two tree hazel species crossed with each other readily, as did the three bristle-husked shrub species. The frequency of blanks was low (<20%) for crosses of the tree hazels, and <50% for interspecific crosses within the group of bristle-husked species. The leafy-husked shrub species could be crossed with each other in all directions, although cluster set on C. heterophylla was low. For crosses of species belonging to different groups, set was generally low and the frequency of blanks high. Nevertheless, a few hybrid seedlings were obtained from several combinations. When used as the female parent, C. californica set nuts when crossed with all other species, indicating possible value as a bridge species. Crosses involving C. avellana were more successful when it was the pollen parent. In crosses with C. avellana pollen, cluster set on C. chinensis was better than on C. colurna and the frequency of blanks was much lower, indicating that it might be easier to transfer nonsuckering growth habit from C. chinensis than from C. colurna. Reciprocal differences in the success of crosses was observed. The following crosses were successful C. californica × C. avellana, C. chinensis × C. avellana, C americana × C. heterophylla, C. cornuta × C heterophylla, C. californica × C. colurna, and C. americana × C. sieboldiana, but the reciprocals were not.

Abstract:
Abstract Germplasm improvement of woody crops through plant breeding depends on effective methods of vegetative propagation, both for evaluation of candidate germplasm and for dissemination of improved varieties. Hybrid hazelnuts [Corylus americana (Walter) x C. avellana (L.)] are being developed as a new crop for the Upper Midwest for their ecological and economic value, but lack of economically viable propagation methods is a significant bottleneck to their wide scale adoption. This paper describes two trials to optimize propagation from hardwood stem cuttings in low-cost humidity tents, using dormant crown suckers collected in the fall. We found that: 1) 2 g.L−1 (2,000 ppm) indole-3-butyric acid (IBA) in a 50% ethanol solution is the best concentration for rooting cuttings of a range of sizes and 2) rooting declines with increasing basal diameter of stems, but increases with increasing length of stem. The thicker cortex of large diameter stems may present a physical barrier to emergence of adventitious roots. Conversely, longer stems have larger stores of carbohydrates, which are essential both for keeping the stems alive until roots can be developed, and for providing the building blocks for growing those roots. Index words: Propagation, Corylus americana (Walter), Corylus avellana (L.), rooting, indole-3-butyric acid. Chemicals used in this study: indole-3-butyric acid (IBA).

Abstract Hybrid hazelnuts [Corylus americana (Walter) x C. avellana (L.)] are being developed for their ecological and economic value as a new crop for the Upper Midwest, but lack of economically viable propagation methods is a significant bottleneck to their wide scale adoption. Thus far, mound layering has been the primary propagation method, but layering cannot produce the numbers of plants needed for large-scale production. Rooting hardwood stem cuttings is a possible alternative. In a factorial experiment, we evaluated two pretreatments, blanching with sawdust and application of IBA, applied to rapidly growing first year collar suckers in the field five months ahead of collection for rooting. These treatments simulated mound layering, but without girdling. Sawdust by itself significantly increased both quantity and quality of subsequent rooting, but IBA pretreatment in combination with sawdust produced even better results. Stem cuttings were rooted in a growth chamber, set at 22 C (72 F) and 60% relative humidity, with PAR of 320 umol.m−2 s−1 for 16 hours per day. The lack of heat stress in the growth chamber likely also contributed to relatively high rooting relative to the humidity tents used in previous trials. Index words: Propagation, Corylus americana (Walter), Corylus avellana (L.), rooting, etiolation. Chemicals used in this study: indole-3-butyric acid (IBA). Species used in this study: hybrid hazelnuts [Corylus americana (Walter) x Corylus avellana (L.)].

La presente investigación tuvo como fin hacer una prospección del comercio del fruto seco del Avellano Europeo, desde el punto de vista del comercio internacional. Se realizó como memoria de grado y se presenta dividido en 3 partes-capítulos: la primera parte tiene como objetivo el presentar los antecedentes de la comercialización del avellano europeo producido en Chile; el segundo capítulo está enfocado al comercio internacional del fruto del avellano europeo, separando entre las avellanas con cáscara y avellanas sin cáscara, y el tercer capítulo se orienta a las variables críticas que intervienen en el proceso de comercialización de este producto. La información para la realización del presente trabajo fue recopilada acudiendo a las fuentes tradicionales de información, entregada por organismos públicos y privados y también a través de entrevistas con participantes del negocio de avellanas y personas de los organismos públicos como el Servicio Agrícola y Ganadero (SAG). El presente estudio determinó que son tres las variables críticas más importantes que influyen en el comercio de este producto. Estas son: rendimiento de la fruta que determina su comercialización en forma de con cáscara o sin cáscara, restricciones fitosanitarias que existen en los principales países importadores del avellano con cáscara y condición arancelaria y los TLC. El avellano europeo es un producto emergente, cuyas variables críticas representan los principales desafíos para el desarrollo de la industria y consolidación del fruto seco en la canasta exportadora chilena.

Abstract:
The difficulty of increasing taxane production and reducing its costs has prompted a search for new biotechnological sources. The unexpected discovery of taxanes in Corylus avellana has generated considerable interest in studying this plant and its derived cell cultures. We therefore focused this work on the study of cell suspension cultures of C. avellana as a new biotechnological approach to the production of taxol and related taxanes. With this goal, we optimized a scale-up process, the type of elicitor and moment of elicitation, cell culture growth, and an analytical technique to detect the compounds of interest. Also, C. avellana tree extracts were analyzed, leading to the identification of compounds with antiproliferative activity against cancer cell lines. These results provide new insights into cell suspension cultures of C. avellana and how to increase taxane production.
La dificultat d’incrementar la producció de taxans i de reduir els seus costos ha promogut la cerca de noves fonts biotecnològiques. El fet de trobar taxol i taxans a Corylus avellana ha incrementat l’ interès en el seu estudi. Per aquesta raó, hem focalitzat aquest treball en trobar noves estratègies per la producció de taxans en suspensions cel•lulars de C. avellana. Amb aquest objectiu, hem optimitzat el procés d’escalat, l’elicitació i el creixement dels cultius, així com la tècnica analítica per identificar i quantificar els compostos d’interès. A més, hem estudiat diversos extractes de l’arbre, fet que ens ha permès trobar altres compostos amb activitat antiproliferativa en línies cel•lulars cancerígenes. Tots els resultats proporcionen noves eines pel cultiu de suspensions cel•lulars de C. avellana i per a l’increment de la producció de taxans.

Abstract:
L'assecatge i emmagatzematge de l'avellana són processos molt importants en la
tecnologia postcollita de l'avellana que poden influir en la seva qualitat i idoneïtat per al
consum. Aquesta Tesi estudia la cinètica d'assecatge i la influència de les condicions
d'assecatge i frigoconservació sobre la qualitat de l'avellana; prèviament, però, es fa un estudi
del comportament higroscopio de l'avellana.
Per a l'estudi del comportament higroscòpic de l'avellana s'han determinat les corbes
de rehidratació i les isotermes d'humitat d'equilibri a diferents temperatures. L'equació de
Peleg dóna un bon ajust a les corbes de rehidratació; mentre que dels diferents models
matemàtics als que s'han ajustat les dades experimentals d'humitat d'equilibri, l'equació de
G.A.B. és la que prediu millor les isotermes d'humitat d'equilibri de l'avellana.
L'estudi de la influència de les condicions de frigoconservació sobre la qualitat de
l'avellana en gra s'ha fet emmagatzemant, durant un any, mostres d'avellana de les varietats
Negret, Pauetet i Tonda Romana a temperatures entre 0°C i 10°C i a humitats relatives de
40% i 60%. Per avaluar la qualitat de l'avellana emmagatzemada s'ha determinat l'índex
d'acidesa, els coeficients d'extinció K232 i K270, el període d'inducció, l'activitat dels enzims
lipasa, peroxidasa i polifenoloxidasa, l'evolució del color i l'acceptació organoléptica de
l'avellana. Els resultats obtinguts posen de manifest que la conservació de l'avellana en
aquestes condicions de frigoconservació és bona.
Per a l'estudi de la influència de les condicions d'assecatge sobre la qualitat de
l'avellana s'han realitzat experiències d'assecat amb avellana de la varietat Negt'et en gra i en
closca i amb avellana de la varietat Pauetet en gra, a temperatures entre 30°C i 80°C, i s'ha
determinat el grau d'alteració de la fracció lipídica i l'evolució del color de l'avellana. Els
resultats obtinguts indiquen que les temperatures d'assecat superiors a 50°C afavoreixen el
desenvolupament dels enranciments hidrolític i oxidatiu.
En darrer terme, s'ha estudiat la cinètica d'assecat de l'avellana ajustant les corbes
d'assecat en capa prima a diferents equacions. També s'ha realitzat la validació de l'algoritme
de simulació de l'assecat d'avellana en llit profund que utilitza el model de Nellist i l'equació
de velocitat d'assecat de Page, mitjançant la realització d'experiències d'assecat industrial
d'avellana.

Abstract:
The anatomy of bifurcations in trees requires further scientific investigation as the current anatomical model for them is logically flawed. The provision of a better model will assist in scientific studies of woody plants, the risk assessment of junctions in mature trees and provide bio-inspiration for Y-shaped joints in composite materials. In this study, the xylem formed in the central axis of a hazel (Corylus avellana L.) bifurcation is shown to provide a disproportionately greater amount of its tensile strength. CT scanning identified that this centrally-placed xylem was 28.1% denser, with 63% less vessels formed in this tissue, such vessels being 50.5% of the diameter and 32.5% of the length of those formed in adjacent stem tissues. The wood grain pattern at the bifurcation apices were 22 times more tortuous, forming interlocking patterns that acted to resist tensile forces by requiring the extraction or breaking of wood fibres along their length (the axial tensile strength of wood). Subsequent tests confirmed that this conferred more than 100% additional tensile strength to these specialised xylem tissues. These findings provided the basis of a novel anatomical model for bifurcations in woody plants. Further to this, the effects of several factors upon junction strength and biomechanical behaviour were assessed in bifurcations of hazel, identifying the weakening effect of bark inclusions and three types of artificial modification as well as differences in wind-induced movement between bifurcation types. This study concludes that further investigations of bifurcations in a wider range of woody plants and observations of the developmental stages of the interlocking wood grain patterns found at bifurcations would usefully add to existing knowledge.

Abstract:
During the 1990s, a question posed by new and intending growers of hazelnuts was “What is the best variety to plant when establishing a commercial orchard?” Although existing growers had a range of views on this matter, there had not been any scientific studies to evaluate the range of cultivars available in Australia. Although hazelnut cultivars were introduced to Australia in the mid-Nineteenth Century, there had been very limited industry development compared to other cool climate deciduous tree crops such as pome and stone fruits. In the 1970s many cultivars were imported from overseas, but there was no systematic evaluation of this material. In 1994, the author of this thesis obtained a grant from the Rural Industries Research and Development Corporation (RIRDC) to undertake an assessment of hazelnut cultivars and their potential for Australian conditions. The evaluation involved planting a range of cultivars at 5 field sites. Two were in New South Wales, 2 in Victoria, and 1 in Tasmania. There was variation between the sites in soil types and climate. A randomised block design was used with cultivars as treatments within blocks. Observations and measurements were recorded for tree growth, floral phenology, nut yields and the characteristics of both nuts and kernels. All sites had supplementary irrigation and common management practices. 1-year old hazelnut whips were planted at a spacing of 3 m x 5 m. Automatic weather stations were located at each site. There were major differences between cultivars, in terms of their vigour of growth, floral phenology, nut yields and kernel characteristics. In addition to the cultivar effects, soil type was a major factor influencing tree growth, as was rainfall. Cultivars with high vigour included ‘Barcelona’ and the Australian selection ‘Tokolyi/Brownfield Cosford’ (‘TBC’). Those of low vigour were ‘Tonda Gentile delle Langhe’ (‘TGDL’), ‘Negret’ and ‘Wanliss Pride’. There were significant interactions between cultivars and the sites in tree growth and nut yields. Timing of male and female anthesis was strongly influenced by cultivar and seasonal conditions. All cultivars were protandrous. The commencement of pollen shed ranged from late-May, for the cultivars ‘TGDL’ and ‘Barcelona’, to early August for ‘Hall’s Giant’. Chill hour requirements appeared to be the main factor influencing timing of pollen shed. Female anthesis was also spread over a period of several weeks with early cultivars being ‘Atlas’ and ‘Tonda di Giffoni’, late cultivars were ‘Ennis’, ‘Casina’ and ‘Hall’s Giant’. Studies with cut branches in controlled temperature environments indicated that catkins had a relatively high post-chill heat requirement compared to female inflorescences. The differences between cultivars in post-chill heat requirements for catkins were small. The relative dates of flowering across cultivars were found to be highly predictable. This, coupled with published data on genetic incompatibility, made it possible to recommend cultivars as pollinisers for the main nut-yielding cultivars. There were significant differences between cultivars in the date of bud break; ‘TGDL’ and ‘Tonda di Giffoni’ were early (late August) whereas ‘Hall’s Giant’ was late (late September). Nut yields were highly influenced by cultivar, vigour of growth, site and seasonal rainfall. Low rainfall in one season greatly reduced nut yields. High growth rates at one site lead to a closed canopy 7 years from planting with peak yields. Soil characteristics were a main factor influencing tree growth and nut yields. The best tree growth and highest levels of production were achieved on a deep, well drained, fertile loam soil. The characteristics of nuts and kernels were strongly influenced by cultivar, although seasonal conditions influenced nut and kernel size and the degree of kernel fill. An overall evaluation of cultivars was based on nut and kernel yields as well as kernel characteristics to meet market requirements. On average, ‘Ennis’ gave the highest yields of the in-shell cultivars. The cultivars ‘Barcelona’ and ‘TBC’ produced the highest average yields, although their relative performance varied between sites. These cultivars were considered best suited for snack foods and catering with 15-17 mm kernels. ‘Tonda di Giffoni’ produced moderately high yields, varying across sites, with kernels suitable for the confectionery market. Under favourable conditions ‘Barcelona’ achieved nut yields of 3 tonnes/ha within 6 years from planting. Potential areas in Australia for hazelnut production were identified, based on a set of recommended climatic parameters and soil characteristics.

Abstract:
Hazelnuts are mostly non-dormant at harvest but develop seed dormancy after a few days of storage. The seeds have been classified as recalcitrant since they cannot be stored for more than one year under ambient conditions. Cryopreservation has not been satisfactory so an alternative protocol is required. To test for recalcitrance, chilled non-dormant seeds (control) were compared with gibberellic acid (GA3) treated seeds during 6 weeks storage at 5°C or at ambient temperature. Control seed moisture content (MC) was 14-15% compared with 20% for GA3 treated seeds. No change in viability was noted until the end of 6 weeks at ambient temperature, when infection proliferated. Reduced germinability, associated with increased leachate conductivity, was noted on all treatments and controls, with ambient temperature storage most harmful for seed viability. This supports classification of hazel seeds as recalcitrant. However, orthodox behaviour could be induced by reducing seed moisture to <6%, showing survival for more than 3 years at -20°C with acceptable germinability and producing healthy seedlings. Pathogen tests show that 6 weeks chilling to break seed dormancy may activate the seeds’ internal protective mechanisms, thereby reducing infection and enabling germination and healthy seedling establishment. The link between seed viability and protection from free radicals and pathogens was examined. Antioxidant activity in hazelnut seed associates (such as endocarp, funiculus and testa) was found to be much higher than in the seed embryo, perhaps indicating that hazel seeds have natural protective mechanisms within the pericarp. Antioxidant activity of seed associates increased during chilling, indicating their role in protecting the seed. Nevertheless, TTC test revealed that seeds acclimatised to ii < 6% MC and stored at 5°C for 45 weeks showed viability loss due to damage of the embryonic axes, probably caused by free radicals. Initial tests to stabilise seed moisture content showed that reduction in seed moisture did not impose dormancy and seed moisture content (MC) stabilisation resulted in > 80% germination but many abnormal seedlings. Dormancy reversibility was tested by treatments T1 (one period at 15°C) and T2 (two periods at 15°C), designed following a consideration of the natural environment. Both resulted in reduced germination, delayed seedling emergence, increased abnormal seedlings, reduced seedling height and decreased internode numbers. To test the role of temperature in reduced seed performance, non-dormant hazelnuts were held at either 5°C or at ambient temperature for up to 6 weeks. Seeds from both sets exhibited high viability, but germinability was significantly decreased in the ambient temperature set, associated with increases in leachate conductivity and infection. Work in this thesis has confirmed that dormancy was broken by chilling, with gradually increasing germination as chilling time was increased. Germination increased with increase in chilling and reduction in infection. No infection was recoreded after 6 weeks chilling. It is most likely that protective agents are produced causing suppression of infection. In these experiments it was observed that not all germinated seeds produced healthy seedlings, suggesting that germination tests without observation of seedlings may give an incomplete assessment of germination success. Assessment using the Tetrazolium test (TTC) was found to be much more dependable and it was also possible to detect damage to specific tissues that might result in unhealthy seedlings.
