“…7 summarizes the results arising from the present work, as well as information from Cantagallo et al (2004) and Lindström et al (2007). The scale is also coupled to early and late developmental sunflower stages of Marc and Palmer (1981) and Schneiter and Miller (1981).…”

“…The first one, proposed by Marc and Palmer (1981), defines 10 floral stages (FS) which encompass the interval between the time when the vegetative apex expands radially and stops forming leaves (FS 1) up to the moment when the differentiation of floral primordia is completed Genotype effects on grain weight in sorghum were established before fertilization through differences in ovary volume, which in turn were associated with the size of the apical meristem during flower development (Yang et al 2009). Lindström et al (2007) concluded that the potential size of the pericarp in sunflower was determined during the pre-anthesis period since no cell division was observed in the ovary wall at anthesis.…”

“…where the largest proportion of lipids and dry matter is stored (Connor and Hall, 1997) For sunflower , the change with time of pericarp and embryo dry weight (Villalobos et al 1996;Connor and Hall 1997;Seiler 1997;Lindström et al 2000Lindström et al , 2007Mantese et al 2006;Rondanini et al 2006Rondanini et al , 2009 as well as pericarp histogenesis (Roth 1977;Percie Du Sert and Durrieu 1988;Lindström et al 2000Lindström et al , 2007Mantese et al 2006) have been described. The differentiation of the pericarp and the lag phase of embryo growth end about 10 days after anthesis.…”

“…The events described here were linked to the reproductive stages of Schneiter and Miller's phenological scale (1981) and to a thermal time scale (Qadir et al 2007). In addition, we propose a unified scale that integrates information from the present work and data of pericarp histogenesis included in Lindström et al (2007), and that is explicitly linked to the scales of Marc and Palmer (1981) and Schneiter and Miller (1981).…”

In sunflower (Helianthus annuus L.) there has been an intense genetic selection for achenes with agronomic value, such as greater weight, oil content, and disease resistance.However, the information regarding the anatomical events that control their growth and maturation is surprisingly scarce.The aim of the present work was to study sunflower male and female sporogenesis and gametogenesis as well as cell division and enlargement and tissue differentiation in the ovary and the embryo, linking the timing of these events to two frequently used phenological scales and a thermal time scale. In addition, we propose an ontogenetic scale that integrates the results of the present work to that of previous studies on sunflower reproductive development. The unified scales presented here provide a framework for others to investigate the relationships uncovered in this study in different genetic backgrounds and under different growing conditions.

“…The other constituents of sunflower achene are proteins (18%), cellulose (15%), water (9%), carbohydrates and minerals (14%) (Prolea, 2009;Roche, 2005). The achene can be separated in two parts: the hull or pericarp, which represents between 20 and 40% of achene weight (Connor and Hall, 1997;Lindström et al, 2007) and the kernel. The black hull is mainly composed of lignin and cellulose with low protein (4%) and lipid (5%) content (Cancalon, 1971;Knowles, 1978).…”

-Sunflower appears as a potentially highly competitive crop, thanks to the diversification of its market and the richness of its oil. However, seed oil concentration (OC) -a commercial criterion for crushing industry -is subjected to genotypic and environmental effects that make it sometimes hardly predictable. It is assumed that more understanding of oil physiology combined with the use of crop models should permit to improve prediction and management of grain quality for various end-users. Main effects of temperature, water, nitrogen, plant density and fungal diseases were reviewed in this paper. Current generic and specific crop models which simulate oil concentration were found to be empirical and to lack of proper evaluation processes. Recently two modeling approaches integrating ecophysiological knowledge were developed by Andrianasolo (2014, Statistical and dynamic modelling of sunflower (Helianthus annuus L.) grain composition as a function of agronomic and environmental factors, Ph.D. Thesis, INP Toulouse): (i) a statistical approach relating OC to a range of explanatory variables (potential OC, temperature, water and nitrogen stress indices, intercepted radiation, plant density) which resulted in prediction quality from 1.9 to 2.5 oil points depending on the nature of the models; (ii) a dynamic approach, based on "source-sink" relationships involving leaves, stems, receptacles (as sources) and hulls, proteins and oil (as sinks) and using priority rules for carbon and nitrogen allocation. The latter model reproduced dynamic patterns of all source and sink components faithfully, but tended to overestimate OC. A better description of photosynthesis and nitrogen uptake, as well as genotypic parameters is expected to improve its performance.Keywords: Seed oil concentration / sunflower / genotype / crop management / crop model Résumé -Analyse et modélisation des facteurs contrôlant la teneur en huile chez le tournesol. Le tournesol apparaît comme une culture potentiellement compétitive grâce à la diversité de ses débouchés et de la richesse en huile de ses graines. Cependant, la teneur en huile de la graine (TH) -critère commercial pour la trituration -dépend d'effets génotypiques et environnementaux ce qui en complexifie parfois la prédiction. Nous faisons l'hypothèse qu'une meilleure compréhension de la physiologie de l'accumulation d'huile combinée à l'utilisation de modèles de culture permettrait d'améliorer la prédiction et la gestion de la qualité du grain pour différents usages. Les principaux effets de la température, de l'eau, de l'azote, de la densité de peuplement et des maladies fongiques sont revus dans cette synthèse. Les modèles de culture génériques et spécifiques apparaissent empiriques pour ce qui concerne TH et manquent d'évaluation pour ce critère. Récemment, deux approches de modélisation intégrant des connaissances écophysiolo-giques ont été développées par Andrianasolo (2014, Modélisation statistique et dynamique de la composition de la graine de tournesol (Helianthus annuus L...
