Cichorium intybus L., (chicory) is employed in various traditional medicines to treat a wide range of diseases and disorders. In the current investigation, two new naphthalane derivatives viz., cichorins D (1) and E (2), along with one new anthraquinone cichorin F (3), were isolated from Cichorium intybus. In addition, three previously reported compounds viz., β-sitosterol (4), β-sitosterol β-glucopyranoside (5), and stigmasterol (6) were also isolated from Cichorium intybus. Their structures were established via extensive spectroscopic data, including 1D (1H and 13C) and 2D NMR (COSY, HSQC and HMBC), and ESIMS. Cichorin E (2) has a weak cytotoxic effect on breast cancer cells (MDA-MB-468: IC50: 85.9 µM) and Ewing’s sarcoma cells (SK-N-MC: IC50: 71.1 µM); cichorin F (3) also illustrated weak cytotoxic effects on breast cancer cells (MDA-MB-468: IC50: 41.0 µM and MDA-MB-231: IC50: 45.6 µM), and SK-N-MC cells (IC50: 71.9 µM). Moreover compounds 1–3 did not show any promising anthelmintic effects.

Labelled 7-hydroxycoumarin (umbelliferone) was converted efficiently to 6,7-dihydroxycoumarin (aesculetin), the aglycone of the glucoside cichoriin, in Cichorium intybus L., and earlier studies contraindicating caffeic acid as a precursor were confirmed. Umbelliferone, which occurs in this species, is thus indicated to be a natural intermediate in aesculetin biosynthesis. Administered umbelliferone was readily converted to its 7-O-glucoside, skimmin, an observation consistent with participation of skimmin in the biosynthetic pathway to cichoriin. This evidence for derivation of aesculetin from umbelliferone provides further support for the theory that polyoxygenated coumarins are, in general, elaborated by additional oxygenation of umbelliferone. Implications of this concept for the evolution of the biosynthesis of coumarins are discussed.

Chicory (Cichorium intybus L) is a deep rooted biennial (or weakly perennial) composite that is grown as an annual in South Africa for its parsnip-like root. In its wild state the plant is a perennial with thin fibrous roots, but, through selection and propagation, cultivars with large, fleshy roots have been developed. From a purely horticultural standpoint, chicory is of interest as a pot-herb, a salad plant and as a root (Bailey, 1942) . As a root, the chicory plant represents an important article of commerce. In South Africa, the plants are grown virtually exclusively for their roots which, after drying, roasting and grinding, are used as an additive to, or substitute for, coffee (Introduction p. 11)

La chicorée industrielle, Cichorium intybus L. var. sativum, accumule une grandediversité de métabolites spécialisés. Ces métabolites montrent une grande variété destructures, activités et fonctions qui sont considérables d’un point de vue physiologique, mais aussi pour des applications humaines telle qu’en santé humaine et animale, en agronomie et autres diverses industries.Ce travail se concentre sur deux métabolites spécialisés de C. intybus : une phénolamide inhabituelle, la tétracoumaroyl-spermine (TetraSpm), et l’acide isochlorogénique (3,5-diCQA). Il constitue une contribution aux caractérisations biochimique, physiologique ainsi qu’à l’étude de l’histoire évolutive d’enzymes impliquées dans la biosynthèse de ces deux acides hydroxycinnamiques conjugués. Nous avons utilisé à ces fins des approches bioinformatiques et d’ingénierie moléculaires.Concernant la TetraSpm, nous avons démontré l’action successive des deux CiSHTs(Spermine Hydroxycinnamoyl Transférases) in vivo dans sa voie de biosynthèse. Nousavons exploré l’influence du ratio de polyamines libres disponibles et des caractéristiques structurelles des protéines SHT sur leurs activités catalytiques. En outre, nous avons produit une protéine chimérique capable de catalyser la production de TetraSpm en une seule étape. L’étude du métabolisme du diCQA chez C. intybus a impliqué l‘identification et la caractérisation préliminaire de gènes cibles appartenant à la famille enzymatique des GDSL-lipases like. De plus, cela a mis en évidence la diversité des acyltranférases impliquées dans le métabolisme spécialisé des plantes. Les rôles physiologiques et fonctions de la TetraSpm et du diCQA restent à déterminer. Cependant, la conservation de la TetraSpm au sein de la famille des Astéracées suggère son importance dans leur histoire évolutive, et les propriétés thérapeutiques du diCQA sont d’un grand intérêt en santé humaine. Ainsi, la compréhension de leurs voies de production permettra de leurs reconstitutions dans des systèmes hétérologues plus efficaces grâce à l’ingénierie moléculaire et par conséquent à la valorisation de ces composés
Industrial chicory, Cichorium intybus L. var. sativum, accumulates a wide array ofpotent specialized metabolites. These metabolites exhibit very diverse structures, activities and functions that are remarkable from a physiological standpoint, but also for their applications such as in human and animal health, agronomy and other diverse industries.This work focused on two specialized metabolites of C. intybus: an unusual phenolamide tetracoumaroyl-spermine (TetraSpm) and 3,5-isochlorogenic acid (diCQA). This research contributes to the biochemical and physiological characterization as well as the investigation of the evolutive history of the enzymes involved in the biosynthesis of these two hydroxycinnamic acid conjugates. We used computational analysis and molecular engineering approaches.We demonstrated the sequential action of the two CiSHTs (Spermine Hydroxycinnamoyl Transferases) in vivo in the biosynthetic pathway of TetraSpm. We investigated the influence of free polyamine availability and structural features on the catalytic activities of SHT proteins. Furthermore, we engineered a chimeric protein able to catalyze the production of TetraSpm in a single step.The study of diCQA metabolism in C. intybus involved the identification and preliminary characterization of target genes belonging to the GDSL-lipase like enzymatic family. Moreover, it emphasized the diversity of plant acyltransferases involved in specialized metabolism. The physiological roles and functions of TetraSpm and diCQA are still to be determined. However, the conservation of TetraSpm among the Asteraceae family suggests that it plays a significant role in their evolution, and the therapeutic properties of diCQA are of great interest in human health. Thus, deciphering these biosynthetic pathways is crucial for their reconstitution in more efficient systems via molecular engineering and consequently the valorization of these compounds

Tesis para optar al Grado de Magister en Ciencias Agropecuarias, Mención Producción de Cultivos
Existen en el mercado nacional variedades híbridas de radicchio (Cichorium intybus L.), de alto rendimiento y homogeneidad, su limitante es el alto costo de la semilla. La más importante es ‘Leonardo’, de semillas Bejo, que representa 90% del mercado, sin embargo, se cree que existen variedades de polinización abierta que podrían utilizarse como alternativa a los híbridos a un menor costo. Este estudio, buscó seleccionar variedades de polinización abierta con igual o mejor rendimiento exportable que ‘Leonardo’, con el fin de establecer bases de recomendación de cultivares en la zona central de Chile. Se evaluaron 11 variedades de radicchio, en un diseño experimental de bloques completos al azar con cinco repeticiones. El ensayo se realizó en 4 localidades de la zona central de Chile, durante la temporada 2007-2008. En cada localidad se evaluaron 3 fechas de siembra, la combinación localidad x fecha de siembra generó 12 ambientes. Se evaluó el rendimiento exportable, peso de la cabeza, porcentaje de plantas enfermas, emisión prematura de tallo floral y color exportable, se realizaron análisis combinado de varianza, de estabilidad, AMMI, SREG, PLS y componentes principales. El rendimiento exportable de las variedades fluctuó entre 23,34 t ha-1 (‘Leonardo’) y 6,84 t ha-1 (‘CH121’), y de los ambientes entre 25,89 y 8,18 t ha-1 . El análisis combinado de varianza del rendimiento exportable, mostró efecto significativo para GxA. El tipo de radicchio (Treviso o Chioggia) resultó ser la principal causa de interacción para rendimiento exportable. En términos de rendimiento exportable, ‘Ciro’ (Chioggia) podría considerarse como una buena alternativa económica a ‘Leonardo’ en el mega ambiente formado por las tres fechas de siembra de Polpaico, Santo Domingo y Lampa, mientras que ‘Tullio’ (Treviso) podría ser alternativa en las tres fechas de siembra de Padre Hurtado. ‘Ciro’ destacó no sólo porque rindió 18,7% menos que ‘Leonardo’ (P<0,05) sino porque también es más estable que ‘Leonardo’. ‘Tullio’ rindió 24% más que ‘Leonardo’ en las tres fechas de siembra de Padre Hurtado (P<0,05). La reducción del rendimiento exportable se debió principalmente a enfermedades.
In the Chilean national market there are hybrid varieties of radicchio (Cichorium intybus L.) with high yield and homogeneity, its limitation is the high cost of the seed. The most important is ‘Leonardo’, Bejo seed, which represents 90% of the market, however, it is believed that there are open-pollinated varieties that could be used as an alternative to hybrids at lower cost. This study sought to select open-pollinated varieties with equal or better exportable performance than ‘Leonardo’, in order to establish bases on the recommendation of cultivars for the central zone of Chile. Eleven varieties of radicchio were evaluated in a randomized complete block desing with five replications. The trial was conducted in four localities of central Chile, during the 2007-2008 seasons. At each site, 3 planting dates were evaluated. The combination of locality x transplant date generated 12 environments. Exportable yield, head mass, percentage of diseased plants, early flowering bolting and exportable color were evaluated. Combined analyzes of variance, stability, AMMI, SREG, PLS and principal components were made. The exportable yield of the varieties ranged from 23,34 t ha-1 (‘Leonardo’) to 6,84 t ha-1 (‘CH121’), and the environments ranged between 25,89 and 8,18 t ha-1 . The analysis of the exportable yield variance showed significant GxE effect. The type of radicchio (Treviso or Chioggia) was the main cause of interaction for exportable yield. In terms of exportable yield, ‘Ciro’ (Chioggia) could be considered as a good alternative to ‘Leonardo’ in the mega environment formed by the three planting dates of Polpaico, Santo Domingo and Lampa, while ‘Tullio’ (Treviso) could be an alternative in the three planting dates of Padre Hurtado. ‘Ciro’ yield 18,7% less than ‘Leonardo’ (P <0,05) but showed better stability than ‘Leonardo’ and ‘Tullio’ yield 24% more than ‘Leonardo’ in the three planting dates of Padre Hurtado (P <0,05). Exportable yield reduction is mainly due to diseases.

Thesis (DPhilAgric)--Stellenbosch University, 2002
ENGLISH ABSTRACT: South Africa is one of the worlds leading producers of chicory (Cichorium intybus L.). Most of the chicory produced is used locally for the production of instant coffee. Witloof chicory, or Belgian endive, however, is a vegetable crop grown from the root of Cichorium intybus L. var. foliosum. This is done by placing the mature taproot in a controlled, dark environment after vernalization and supplying it with water and nutrients by means of hydroponics. Witloof chicory is new to the South African market and is only produced on a limited scale. Nonetheless, seeing that chicory is successfully grown on a large scale for the coffee industry it seemed reasonable to investigate the cultivation of this essentially unknown vegetable locally. The focus of this study was on the evaluation of new witloof production techniques during the second stage of witloof (chicon) cultivation, also called 'forcing'. To this end, locally grown witloof chicory roots were used in all trials. In order to establish the effects of several irrigation methods on lateral root formation and chicon quality, witloof chicory roots were forced using the conventional means of hydroponic irrigation as well as ebb-and-flood and aeroponic irrigation. Lateral root formation was significantly increased when either ebb-and-flood or aeroponic irrigation was applied compared to that obtained with the conventional method. This increase in lateral root formation was, however, to the detriment of chicon quality (QI), possibly as a result of competition for limited carbohydrate reserves. In an attempt to optimize the aeroponic irrigation method, roots were forced in non-vertical positions. Placing roots horizontally during forcing resulted in a significantly lower marketable chicon yield than where roots were placed vertically. The loss in yield was probably brought about by an increased fallout percentage rather than by a decrease in chicon production. Considering the pivotal role that sucrose plays in the development of the chicory head, sucrose was applied exogenously to the root before and/or during forcing. Dry matter chicon yield was negatively effected by exogenously applied sucrose. This could have been due to an increased incidence of fungal or bacterial infections or causative of roots absorbing less water resulting in the inability of the plant to utilize the applied sucrose during chicon development. Fungal and bacterial infections are known to have a detrimental effect on witloof chicory production. An environmentally friendly product for disease control, 'Desogerme SP®', was used to contain or reduce infection. Irrigation of roots with 'Desogerme SP®' containing nutrient solution increased chicon yield by 31%. From this study it became clear that some new production techniques applied had the potential of improving lateral root formation or quality during growth. However, the conventional way of irrigation remains the most effective compared to the other techniques applied, but could possibly be improved to some extent by incorporating 'Desogerme SP®' either as a pretreatment or in the nutrient solution. A breakthrough was made with the development of the quality index (QI). The ongoing limitation of statistically analyzing quality data of chicons sorted according to quality-classes was overcome by making use of this tool. Despite the fact that the index was developed specifically for use on witloof, it is has the potential of being applied to quality data of a wide variety of crops.
AFRIKAANSE OPSOMMING: Suid Afrika is een van die wêreld se grootste produsente van sigorei (Cichorium intybus L.). Die meeste plaaslik geproduseerde sigorei word vir die produksie van kitskoffie benut. Witloofsigorei, of Belgiese "endive", is egter 'n groentegewas wat vanaf die wortel van Cichorium intybus L. var. foliosum gekweek word. Dit word gedoen deur die volwasse penwortel na vemalisasie in 'n gekontroleerde, donker omgewing te plaas en met 'n hidrokultuurstelsel van water en voedingselemente te voorsien. Witloof is nuut op die Suid Afrikanse mark en word net op beperkte skaal geproduseer. Aangesien sigorei suksesvolop groot skaal vir die koffieindustrie geproduseer word, blyk dit logies om die moontlikhede te ondersoek om hierdie relatief onbekende groente plaaslik te kweek. Die fokus van hierdie studie was gerig op die evaluasie van nuwe produksietegnieke gedurende die tweede fase van witloofproduksie, wat ook as forsering bekend is. Plaaslik gekweekte witloof sigoreiwortels is vir alle eksperimente gebruik. Die invloed van 'n verskeidenheid besproeiingsmetodes is op sywortelproduksie en witloof krop-kwaliteit ondersoek. Witloofwortels is geforseer deur van 'n konvensionele hidrokultuur-stelsel gebruik te maak wat met 'n ebb-en-vloed en 'n lugsproei sisteem vergelyk is. Sywortel-produksie was betekenisvol hoër waar ebb-en-vloed of lugsproei sisteme toegepas is. Hierdie verbetering in sywortel-ontwikkeling was egter tot nadeel van krop-kwaliteit, vermoedelik as gevolg van die allokasie van koolhidrate na sywortels, eerder as na die groeipunt. In 'n poging om die lugsproei besproeiingsmetode te verbeter en om swamsiektes te verminder, is wortels in nie-vertikale posisies geforseer. Wortels wat gedurende forsering horisontaal ingetafel was, het 'n betekenisvol laer opbrengs van bemarkbare kroppe getoon as wortels wat vertikaal geplaas was. Die verlies aan opbrengs kon toegeskryf word aan 'n verhoging van afval, aangesien geen betekenisvolle afname in vars krop-gewig gevind is nie. Aangesien sukrose 'n belangrike rol in die ontwikkeling van die witloofkrop speel, is sukrose voor en tydens forsering aan die wortels toegedien. Droë materiaal krop-opbrengs is negatief deur die toediening van sukrose beïnvloed. Dit kon moontlik as gevolg van 'n verhoogde voorkoms van swam- of bakteriese infeksies gewees het of 'n aanduiding wees dat behandelde wortels minder water geabsorbeer het en die toegediende sukrose nie kon gebruik gedurende krop-ontwikkeling me. Swam- en bakteriese infeksies is bekend vir hul negatiewe uitwerking op witloofproduksie. 'n Omgewingsvriendelike middel, 'Desogerme SP®' is gebruik om siektes te beheer ofte verminder. Wortels wat met 'n 'Desogerme SP®' bevattende voedingsoplossing besproei is, het 'n 31% verhoging in krop-opbrengs getoon. Uit data wat gedurende hierdie studie ingesamel is, blyk dit duidelik dat sommige van die nuwe produksietegnieke wel die potensiaal het om sekere planteienskappe te verbeter. In geheel gesien bly die konvensionele metode van besproeiing die mees effektiewe, wanneer dit vergelyk word met die ander wat getoets is. Die konvensionele metode kan moontlik verbeter word as 'Desogerme SP®' as 'n vooraf-behandeling of as deel van die voedingsoplossing geïnkorporeer word. 'n Deurbraak is met die ontwikkeling van 'n kwaliteitsindeks (QI) gemaak. Ernstige beperkings word met statistiese ontledings van kwaliteitsdata ervaar waar kroppe volgens kwaliteitskiasse gesorteer word. Hierdie probleme is met behulp van die QI oorkom. Ongeag die feit dat die indeks spesifiek vir gebruik by witloof ontwikkel is, het dit die potensiaal om toepassing te vind by 'n wye reeks landboukundige produkte.

Les conditions embryogènes définies pour un hybride de Chicorée à café × Chicorée scarole (hybride «474») n'ont pas permis d'induire une embryogenèse somatique chez des lignées de Chicorées de Bruxelles. De nombreux essais réalisés en modifiant ces conditions inductrices se sont avérés infructueux. Nous avons alors choisi d'étudier comparativement le rôle des polyamines dans des tissus de la plante embryogène (hybride «474») et de la plante non embryogène (lignée «206») cultivés dans des conditions embryogènes. L'hypothèse d'une corrélation entre l'évolution des polyamines endogènes libres (agmatine, putrescine, spermidine et spermine) et l'embryogenèse somatique est considérée. L'analyse des polyamines libres dans des fragments racinaires de l'hybride «474» en culture «in vitro» montre une augmentation (maximum vers le 5ème jour) puis une baisse de la teneur en putrescine et en spermidine au cours de la période d'induction de l'embryogenèse somatique (10 jours). Chez la lignée «206», la putrescine ne présente pas de baisse sensible après le 5ème jour de culture et la spermidine augmente peu. Ces résultats suggèrent que la phase de diminution de la teneur en polyamine pourrait être caractéristique de l'embryogenèse somatique. Ils nous ont conduit à tester l'action d'inhibiteurs de synthèse de la putrescine. Chez l'hybride «474», la DFMA (inhibiteur de l'arginine décarboxylase) supprime l'accumulation de putrescine, diminue celle de spermidine et inhibe l'embryogenèse somatique. Ceci ne se retrouve pas lorsque l'on utilise de la DFMO (inhibiteur de l'ornithine décarboxylase). La spécificité de l'action de la DFMA est prouvée par des expériences de réversion: une restauration de l'embryogenèse somatique inhibée par la DFMA est obtenue par addition de putrescine. La voie de l'arginine décarboxylase serait donc la voie de biosynthèse privilégiée des polyamines chez l'hybride «474» lors de l'induction de l'embryogenèse somatique. L'intervention des polyamines dans l'embryogenèse somatique est discutée et replacée dans un contexte d'étude des phénomènes de morphogenèse

L'investigation a porté sur des symptômes typiques connus et sur des symptômes nouvellement étudiés (sur racines et sur chicons). Les isolats s'apparentent surtout à Erwinia carotovora variété atroseptica. Ils forment un groupe homogène sur le plan biochimique et hérérogène par leurs caractéristiques sérologiques. Des méthodes d'évaluation du pouvoir pathogène des souches bactériennes isolées ont été testées sur plantes entières en cours de forçage et sur organes isolés ; l'incidence du stade de développement de la plante, du niveau d'inoculum et du mode d'inoculation sont étudiés. Le cycle de la bactérie a été abordé par l'étude de la pénétration d'un inoculum à E. C. A. Spontané et artificiel ; l'inoculation des souches durant la phase de végétation de C. Intybus n'aboutit pas à l'expression de la bactériose. Les inoculations en cours de forçage donnent des résultats très variables et surtout dépendants de la température. L'observation de la bactériose dans la plupart des lots témoins expérimentaux permet de conclure à la présence potentielle d'Erwinia dans toutes les racines au forçage : la bactériose à Erwinia est une maladie opportuniste. L'utilisation d'un agent chimique (sulfate de cuivre sous forme de bouillie bordelaise), pouvant modifier qualitativement et quantitativement la flore bactérienne, semble indiquer une possibilité de pénétration d'E. C. A. Au stade végétatif et permet de montrer la présence d'un potentiel infectieux important au niveau des bases foliaires résiduelles après récolte ce potentiel étant responsable de la pourriture ultérieure pendant le forçage. L'étude de quelques facteurs agro-climatiques sur l'expression de la maladie montre que le passé agronomique de la racine (notamment de la fumure azotée au champ) est corrélé positivement à la mortalité des chicons, et que les conditions de conservation des racines ainsi que la température de forçage sont déterminantes pour l'expression de la maladie
The bacterial flora isolated from chicory rot during forcing was characterized. Typical well-known symptoms as well as atypical symptoms encountered during present studies, were investigated on roots and chicons. Isolates were mainly related to Erwinia carotovora subsp. Atroseptica. They formed an homogeneous group from a biochemical point of view and an heterogeneous one with respect to their serological characteristics. Methods for assessing pathogenicity of the isolated bacterial strains were tested on whole plants during forcing and also on isolated organs in order to deter­ m ne the effect of the physiological stage of plants, of inoculum level and of modes of inoculation. The life cycle of bacteria was investigated by studying the penetration in plant tissues of spontaneous and artificial E. C. A. Inocula; the inoculation of strains during the vegetative growth of C. Intybus did not lead to expression of bacteriosis. Inoculations during forcing produced much variable results which were especially dependent on temperature. Observations of bacteriosis in most of the experimental control lots suggest that Erwinia was potentially present in all roots during forcing: this bacteriosis is an opportunistic disease. The use of a chemical (copper sulphate in the form of Bordeaux mixture) able to modify the bacterial flora both qualitatively and quantitatively, indicated that E. C. A. Could possibly penetrate into plants during vegetative growth. It also demonstrated the presence of bacterial infection in leaf residues (left after harvesting of roots) which accounts for subsequent rot during forcing. The study of the influence of some agro-climatic factors on disease expression showed that previous growing conditions of roots (nitrogen fertilization in the field) were positively correlated to chicon mortality, and that the disease expression was highly dependent on the conditions of root storage and forcing temperature

Trois voies differentes d'haploidisation de la chicoree (cichorium intybus l. ) ont ete explorees: 1. La fusion gametosomatique est un procede original permettant d'influencer le deroulement du programme genetique des gametocytes, du fait de l'introduction de leur noyau dans l'environnement cytoplasmique de protoplastes de mesophylle, aptes a regenerer des plantes. La production de plantes haploides par cette technique a ete evaluee sur le modele tabac. Des protoplastes de pollen nature (n) isoles de plantes de nicotiana tabacum (2n=4x=48) resistantes a la kanamycine ont ete fusionnes avec des protoplastes de mesophylle de plantes sauvages de nicotiana plumbaginifolia (2n=20). Des plantes androgenetiques de tabac presentant un cytoplasme de n. Plumbaginifolia ont pu ainsi etre isolees parmi les plantes selectionnees et regenerees. Plusieurs adaptations ont ete experimentees, afin d'etendre ce procede a la chicoree. 2. Une plante de chicoree androgenetique spontanee a ete reperee a l'aide de marqueurs morphologiques parmi 1. 10#5 plantes. L'utilisation d'un marqueur lethal conditionnel au stade plantule permettrait de cribler plus rapidement et plus simplement ces plantes dans une descendance. Afin d'introduire un tel marqueur, une methode efficace et reproductible de transformation genetique de la chicoree via agrobacterium tumefaciens a ete mise au point. 3. Une etude preliminaire, de type rflp, du genome mitochondrial du genre cichorium et de plusieurs autres especes appartenant a la tribu des cichoraceae (asteraceae) a revele une variabilite mitochondriale au sein du genre cichorium et precise les relations entre ce genre et les genres supposes apparentes. Des croisements intergeneriques ont alors ete realises entre la chicoree et plusieurs de ces genres. Differentes barrieres d'incompatibilite de croisement ont pu ainsi etre mises en evidence. Le sauvetage in vitro d'embryons issus des croisements cichorium intybus x cicerbita alpina a cependant permis l'isolement d'une plante de chicoree haploide

In Poland, the bird’s-eye primrose (P. farinosa) is a rare and critically endangered species. Currently, it occurs only in one location in the area of the Jaworki village in Radziejowa Range (of Beskid Sądecki mountains). This is the last of the nine previously existing locations, and the only one occurring in the mountains. To maintain the species, as well as the moutain fen on which it grows, a multiannual conservation program has been implemented, including, among other measures, conducting environmental monitoring and performing active protection procedures. In 2012–2014, studies were carried out, aiming to identify the phenology of P. farinosa in its natural location amid other elements of local flora, and to elaborate reasonably accurate forecast methods of its phenological phases, in relation to the performed procedures. One of the methods was based on comparing subsequent phenological phases of P. farinosa, mainly the dates of flowering and opening of the fruits, with the dates of flowering of other species that commonly occur in the vicinity. On the basis of temperature data from the IMGW meteorological station in Krościenko nad Dunajcem, available via the Internet, an attempt to forecast the phenophases of P. farinosa has also been made, based on the developed network of nearby meteorological stations. A degree-days method was used. Prior to that, a value of base temperature (Tb) characteristic for P. farinosa was assessed, as necessary for further calculations, and the values of SAT (Sum of Active Temperatures, using the formula for GDD values) have been determined for the dates of occurrence of subsequent phenological phases of P. farinosa. These parameters were calculated using temperature data recorded at the location. During the observations, it was established that the dates of flowering for P. farinosa were dependent on the air temperatures during spring. The flowering period of the population in Jaworki took place in the months of April through to June, and it did not exceed 7.5 weeks. P. farinosa is one of the earliest blooming species in that location. Other species, also flourishing during the blooming thereof, included Eriophorum angustifolium, Caltha laeta, Chrysosplenium alternifolium, Oxalis acetosella, and Primula elatior. The full bloom of P. farinosa lasted for about 2 weeks, and it took place between the end of April and the end of the second decade of May. During its full bloom, in that same location, Cardamine pratensis, Geum rivale, and Valeriana simplicifolia also flourished. Trees and bushes from the rose (Rosaceae) family proved to be especially useful in the forecasting of P. farinosa flowering period. During the flowering of P. farinosa, in lower locations, species from the Prunus and Cerasus genera subsequently flourished, followed by the Malus, Sorbus, and Crataegus genera. The opening of P. farinosa fruits was observed in the last days of June or at the beginning of July. The date of commencement and duration of this phase is probably subject also to the degree of air humidity. Although in this period numerous species flourish such as Ononis arvensis, Valeriana sambucifolia, Cichorium intybus, Melilotus alba, Achillea millefolium, Daucus carota, Geranium pratense, and Agrimonia eupatoria, the forecasts based on those are not accurate. When forecasting this phase, as well as the majority of other phases, the SAT value calculation based on the degree-days method works well. The Tb base temperature (threshold temperature) for P. farinosa from Jaworki, determined for its calculation, is 0.75°C. However, for the calculation purposes, the rounded value of Tb = 1.0°C can also be used. When adopting the value of Tb = 0.75°C for calculations, the full bloom of P. farinosa falls within the period in which the SAT values remain between 310°C and 469°C, the optimum (culmination) of the full bloom occurs at about 408°C, and the beginning of capsules opening and release of P. farinosa seeds occur when the SAT values reach 1049°C. For Tb = 1.0°C the full bloom falls within the period in which the SAT values are between 295°C and 449°C, the optimum of full bloom occurs at 390°C, and the capsules begin opening at 1018°C. When using this method, the differences between the forecasted and the observed dates of P. farinose blooming were between –4 and +3 days, and the beginning of opening of its fruits, between –1 and 0 days. In case of no temperature data available from the given location, the forecasting can be also performed based on the data from the IMGW meteorological station in Krościenko. The accuracy of calculations is increased through the implementation of appropriate temperature data adjustments, resulting from the difference of location and height. The temperatures in Jaworki are 2°C lower compared to the station in Krościenko. The dates determined in this way are less accurate than those determined directly at the location, and they differ from the actual dates: in case of full bloom, the difference is in the range of –6 to +2 days, and in case of the beginning of capsules’ opening, it is –2 to –1 days. Probably, it is also possible to implement forecasting based on the data from new automated meteorological stations situated closer to the location, but this can be done only after the adjustment appropriate for every station has been determined and implemented. As demonstrated, the elaborated forecasting methods of P. farinosa phenological phases at the location in Jaworki (Beskid Sądecki) are sufficiently accurate and they may be used in the future as a tool supporting the implementation of measures related to active protection of the species.
