Abstract:
Plagiotropism (angle departure from orthotropic growth) was measured on 360 Norway spruce (Piceaabies (L.) Karst.) clones propagated in 2 subsequent years. The clones were members of 20 full-sib families (18 clones per family) from a provenance hybrid factorial cross involving 10 parents of Norwegian (N) and 10 parents of east-European (EE) origin. The clones from the EE × EE crosses showed an average of 17° and 20° in plagiotropism, those from the N × N group showed 3° and 7° in plagiotropism, while the hybrids (EE × N and N × EE) showed 8° and 13° in plagiotropism in 1988 and 1989, respectively. A large family variation was found in the EE × EE and the hybrid groups (11 and 8.5% of total variation, respectively), but variation was small (3.5%) in the N × N group. The clonal component accounted for 10, 12, and 8.5% of total variation in EE × EE, hybrids, and N × N, respectively. Among the plagiotropic clones, some were heterogeneous with a large within-clone variation and others were homogeneous. The year × family and year × clone components were rather large in EE × EE (5 and 9% of total variation, respectively) but smaller in the hybrids and smallest in N × N. The clones with best growth were not among those with the worst plagiotropic growth. The clonal material is ideal for use in future studies on the genetic and physiological regulation of maturation.

Abstract:
Paspalum vaginatum Swartz stems growing in different directions (tillers, stolons, and rhizomes) were studied to determine the effect of sucrose on the phenomenon of plagiotropism. Sucrose content was found to be notably lower in erect stems than in stems growing horizontally. Plants sprayed with gibberellic acid underwent upward curvatures of stolons and showed a remarkable decrease in sucrose content of stolons and rhizomes. An exogenous supply of a 0.03 M sucrose solution to stolons did not significantly reduce the negative gravitropic curvature induced by excising them from the parent plant, but a more concentrated solution (0.21 M sucrose) maintained the plagiotropic growth. Gibberellic acid treatment overcame the effect of a high sucrose supply and induced upward curvatures even with a high sucrose supply.

Abstract:
Western larch (Larixoccidentalis Nutt.) in the interior northwestern United States produces small and infrequent cone crops resulting in recurrent seed shortages throughout much of its range. Vegetatively propagated planting stock could potentially alleviate shortages of seedlings for artificial regeneration. In a greenhouse study to evaluate suitability of rooted cuttings for forestry, morphology and growth of container-grown stecklings from 1- and 3-year-old ortets were compared with seedlings for up to 6 years after rooting. Newly rooted stecklings produced an average 50% orthotropic, 32% plagiotropic, and 18% suppressed leaders. One-year-old steckling leaders elongated 46% as long as 1-year-old orthotropic steckling leaders after fertilization with 20:20:20 N–P–K at 120 ppm N (p = 0.0001). In subsequent years, orthotropic stecklings elongated more than seedlings. Plagiotropic leaders (average deflection of 24°) developed upright form within 2 years. Competing axillary shoots delayed development of dominant leaders for up to 3 years. Vestiges of atypical habit included small basal stem crooks and sparse branching. Although staking and pruning promoted excurrent habit, poor quality of container-grown stecklings can limit indoor nursery production. Effects of ortet and environment on quality should be examined before stecklings are field tested for use in reforestation.

Abstract:
Success and subsequent growth of fraser fir [Abies fraseri (Pursh) Poir.] cleft grafts were studied in relation to origin and type of scion material in the tree crown. First- and second-order shoots (current-year) were collected from five zones in the crown, ranging from top to bottom, and grafted to 5-year-old fraser fir transplants in April. Success rates were similar for first- and second-order scions, whereas budbreak and subsequent growth were best for first-order scions. In general, results were best for first-order scions taken from the upper crown. Plagiotropism of grafts was similar for all crown zones and shoot types.

Abstract:
Effects of collection date, crown position, and indole-3-butyric acid concentration on rooting and subsequent vegetative growth of softwood cuttings taken from 14-year-old Fraser fir (Abiesfraseri (Pursh) Poir.) Christmas trees were studied. Indole-3-butyric acid levels producing maximum rooting (approximately 50%) varied with crown position and date of severance. Abaxial bending during rooting was greatest for cuttings from the first collection (June 23). Increasing indole-3-butyric acid concentrations decreased abaxial bending of cuttings from the first two severance dates. One year after rooting, plagiotropism was still most pronounced on cuttings collected the first date as a result of active bending of the original cutting segment. Terminal shoot growth was greatest for cuttings from the first and third collections. Lateral budbreak was superior on cuttings collected on the first date. When all factors are taken into consideration, the best combination of rooting and vegetative growth was obtained from upper-crown cuttings which were collected just prior to lignification, wounded, and treated with 1500 ppm indole-3-butyric acid. After one season (one growth flush), rooted softwood cuttings were comparable to 2-year-old plants (two flushes) propagated by hardwood cuttings. The temporal separation of rooting from shoot extension may have been responsible for improving initial vegetative growth.

Abstract:
The objective of this work was to evaluate the growth and productivity of cultivars and progenies of arabica coffee under irrigation by driping in Ceres-Goiás. It was conducted in the experimental area of the Goiano Federal Institute-Ceres Campus. A total of 35 treatments were randomized blocks with four replications, from January 2017 to August 2018. At 30 and 36 months after planting, the diameter of the orthotropic branch, canopy diameter, plant height, number of nodes in the plagiotropic branch 1, length of the plagiotropic branch 1, number of nodes in the plagiotropic branch 2, length of the plagiotropic branch 2, length of the plagiotropic branches 1 and 2, number of nodes of the plagiotropic branches 1 and 2 and productivity were evaluated in 2018. The linear simple correlations were estimated in all evaluated characteristics. There was a difference in growth and yield of the evaluated genotypes. There is a positive correlation among the vegetative characters and the productivity. Catucaí Amarelo 2SL presented higher growth than the other evaluated genotypes. The genotypes Catiguá MG 1, Acauã Novo, Acauã 2 and 8, Catucaí Amarelo 24/137, Catucaí Amarelo 2SL, Asa Branca, Paraíso H419-10-6-2-10-1, Catuaí Vermelho IAC 15, Acauã, Sarchimor MG 8840, IPR 98, Araponga MG 1 and Obatã Vermelho IAC 1669-20 were the ones that had the highest productivity.

Abstract:
ABSTRACT The objective of this study was to evaluate the technical viability and influence of the rootstock age and grafts growth habit on Araucaria angustifolia top grafting. Two rootstocks (8 and 35-year-old) were grafted with grafts originating from two growth habits (orthotropic and plagiotropic). We used the patch grafting technique in the middle and upper third of the crown of 8-year-old trees, and in the middle and lower third of 35-year-old trees, always near the apex in primary branches. The experiments were performed during the fall and spring/2015. The treatments consisted of: 8-year-old rootstocks and orthotropic grafts; 8-year-old rootstocks and plagiotropic grafts; 35-year-old rootstocks and plagiotropic grafts; 35-year-old rootstocks and orthotropic grafts. We evaluated graft survival throughout the experiment and at 16 months, we evaluated their survival, emission, and number and average length of sprouts. Top grafting is technically feasible for araucaria, with better results using younger rootstocks (8-year-old), especially with plagiotropic propagules and grafting in fall/2015 (71.9%). Growth habits of the grafts are maintained identically as original, independently of rootstock growth habit.

Este trabalho tem por objetivo um estudo de convergências entre a crítica, a poesia e o método de tradução de Haroldo de Campos. Para tal, propomos a plagiotropia, enquanto conceito de sua crítica, como um vórtice que possibilita diálogos entre os princípios construtivos de sua poesia e de seu método de tradução, articulando, assim, uma proposta que aborda as três frentes de sua produção. A plagiotropia, com o caractere da obliquidade, configura-se como o diferencial, o particular que singulariza os processos de releitura da tradição praticados por Campos. O nosso trabalho divide-se em dois blocos capitulares. Em cada um destes, a discussão foi articulada de maneira que gire em torno do diálogo entre a plagiotropia e uma porção da obra de Haroldo de Campos. No nosso primeiro bloco capitular, “A transgressão luciferina: a tradição vira serpente”, temos uma discussão teórica sobre o que é a plagiotropia, e quais são os caracteres que a configuram. No segundo, “O voo das letras e o pacto do tudo torto: lendo as frestas da tradução”, inspirados por uma leitura metafórica do pacto de Fausto com Mefistófeles, como o pacto do artista com a transgressão, exploramos a poiesis diabólica em Goethe, a relação da obliquidade com a desautomatização, etc., e com conceito de tradução como “transluciferação”. Nosso último capítulo traz um estudo plagiotrópico da tradução das duas cenas finais de Fausto II, de Goethe, vertidas sob a égide da transcriação, por Haroldo de Campos.

Abstract:
Le caféier Coffea arabica var. Laurina, aussi appelé Bourbon Pointu, est apparu à la Réunion suite à une mutation spontanée de la variété Bourbon. Cette mutation Laurina, monolocus et récessive, a des effets pléiotropiques qui différencie le Bourbon pointu du Bourbon. Au niveau morphologique, elle se caractérise par un nanisme, un port pyramidal et une forme pointue de ses graines. A un niveau moléculaire, la teneur des grains en caféine est fortement réduite. Malgré des caractéristiques agronomiques d'intérêt et d'excellentes qualités organoleptiques, peu d'études sont disponibles sur ce mutant naturel. Ce travail a ainsi pour objectif d'étudier la mutation Laurina et d'en caractériser les effets afin de mieux décrire les cascades de réaction mises en place. Il se base sur la comparaison du Bourbon pointu avec sa variété parente Bourbon. Au niveau morphologique, des mesures de croissance végétative ont permis l'analyse et l'explication de la forme pyramidale du mutant. Au niveau histologique, l'étude de l'apex, centre initiateur des organes de surface, et de différents entre-noeuds de l'axe orthotrope a permis d'expliquer l'origine du nanisme en terme de division et d'élongation cellulaire. Des hypothèses quant à l'action de la mutation Laurina sur certaines hormones ont été émises à partir des résultats d'application de gibbérelline exogène. Ces études macro et microscopiques ont été couplées au niveau moléculaire à la recherche de gènes différentiellement exprimés entre les deux variétés. La comparaison des transcriptomes des deux variétés à un stade précoce post-cotylédonaire avait pour but la recherche de gènes candidats impliqués dans les premières cascades de réactions menant aux effets pléiotropiques observés. Le clonage différentiel basé sur la méthode SSH (Hybridation Suppressive Soustractive) couplé à une étape de tri à haut débit (macro-array) a été appliqué à ces fins. L'ensemble des résultats décrit plus précisément les effets pléiotropiques induits par la mutation Laurina. La description précise des effets pléiotropiques de la mutation ouvre des pistes quant à la caractérisation moléculaire de la mutation à travers une approche gène candidat.

Abstract Following infection with the soil bacterium Agrobacterium rhizogenes, most dicotyledonous plants develop the so-called hairy root syndrome (Elliot 1951). The adventitious hairy roots can be cultured in vitro where they grow in a characteristically highly branched and plagiotropic fashion (David et al. 1984) and, in common with the crown gall tumours, produce unusual amino acid derivatives called opines (Petit and Tempé 1985).
