“…In order to determine the endo-and eco-dormancy release, 1-year-old fruiting shoots were randomly collected periodically from December to March from the west and top sector of the canopy (Viti et al 2003). At each sampling, from the median-apical part of the fruiting shoots, flower buds (n = 45 per cultivar in 3 replicates) were sampled and fresh weighted.…”

Environmental and climatic conditions affect the flower bud growth, flowering and yield performance of fruit species. Temperature and water availability appear to be important factors for temperate fruit trees in mild climates. The aim of this research was to study the involvement of temperature regime on biological processes, such as xylem differentiation and dormancy evolution, in apricot flower buds (Prunus armeniaca L.). Over 3 consecutive years, biological and anatomical investigations were carried out in Tuscany (Italy) and Murcia (Spain) on two cultivars characterized by a different chilling requirement (CR): Currot, a traditional Spanish cultivar with a very low CR, and Stark Early Orange (SEO), a North American cultivar with a very high CR. Currot had a regular bearing, and was characterized by a synchronism between endodormancy release and xylem differentiation. On the other hand, SEO showed an irregular flower bud growth leading to flowering and fruit-set failure, even with a high level of chilling accumulation. No relationship was found in SEO between xylem development and flower bud growth reactivation. The de-synchronism between these processes could determine the poor adaptability to different environmental areas of SEO cultivar, and its very high CR is not the main hypothesised cause of the altered flower bud development.

“…The crop load affects varied characteristics such as distribution of assimilates, fruit size, fruit chemistry, and total plant yield. Position of fruits within an infl orescence or within a canopy affects maturation and sampling procedures across a wide range of architecture types (De Silva et al, 2000;Miles et al, 1996;Viti et al, 2003). Despite this broad knowledge base indicating fecundity and location of a reproductive organ within the plant infl uence many characteristics, past ALS-PDC researchers have ignored the need to document this information from sampled cycad plants.…”

Consumption of Cycas micronesica seed tissue has been associated with the amyotrophic lateral sclerosis–parkinsonism dementia complex (ALS–PDC) of the Western Pacific. However, failures to document vital plant and neighborhood descriptors and pronounced variability in toxin concentrations noted within and among studies obfuscate decades of research on this subject. We discuss the theoretical and experimental constraints of plant tissue sampling in relation to human disease research. Comparisons are made between this approach and methods used throughout the history of ALS–PDC research, most notably very recent reports concerning β-methyl-amino-alanine. Methods for studying possible plant neurotoxins need to be standardized and must follow rigorous criteria to be valid in principle. Our discussions reveal why these criteria are essential and highlight the impact that natural variations have on environmental toxin quantification and interpretation. Past research on cycad toxins is deficient on experimental and theoretical grounds, and interpretation of published data is dominated by ambiguities. This area of study as conventionally conceived and carried out needs transforming. We argue that future empirical studies should honor appropriate plant science standards concomitantly with medical science standards. This dual focus will ensure appropriate sampling scheme, sample size, and reporting of background plant and community factors known to influence phenotypic plasticity.

“…Parmi celles-ci, l'amandier (Prunus amygdalus Stokes), l'abricotier (P. armeniaca L.) et le pêcher (P. persica L.), tous trois de la tribu des Prunées, sont pour le premier d'origine asiatique transcaucasienne (Mouterde, 1969) et, pour les deux autres, chinois (Mabberley, 1987), mais naturalisés au Moyen-Orient où ils sont cultivés pour la consommation de la graine pour le premier et des fruits pour le second et le troisième ainsi que pour certaines propriétés cosmétiques locales (Viti et al, 2003). Actuellement la sélection culturale, au Liban, est artisanale, réalisée par la technique du greffage.…”

Résumé.-Au Liban, Prunus amygdalus Stokes, P. armeniaca L. et P. persica L.(Rosacées) sont cultivés pour leurs propriétés nutritionnelles et cosmétiques. La morphologie pollinique fine a été étudiée, pour trois échantillons prélevés sur les trois espèces, afin de mettre en évidence des caractères polliniques distinctifs. Un traitement numérique des principaux caractères polliniques a été réalisé afin de déterminer la morphologie des grains de pollen, la stéréostructure du tectum et les variations de dimensions (valeurs moyennes, minimales, maximales) de l'axe polaire (P) et du diamètre équatorial (E). permettant une caractérisation plus précise des trois espèces de Prunus.Mots clés : Prunus -morphologie pollinique -palynologie -stéréostructure.Abstract.-In Lebanon, Prunus amygdalus Stokes, P. armeniaca L. and P. persica L. (Rosaceae) are cultivated for their nutritional and cosmetic properties. Fine pollinic morphology was studied, for three samples taken out of the three species, in order to try to highlight distinctive pollinic characters which would make it possible to select populations each one of these presenting characters in order to reinforce genetic variability. Numerical treatment of principal pollinic characters was carried out in order to determine the morphology of the grains of pollen, stereostructure of the tectum and the variations of dimensions of the polar axis (P), of the equatorial diameter (E): average, minimum, maximum values. The characters of the three species enable us to show the existence from three botanical species in the genus Prunus.
