Capsicum annuum is among the five domesticated species: Capsicum (frutescens, annuum, baccatum, chinense and pubescens) the most cultivated in the world. It adapts quite well to dry and hot environments. Environmental conditions have a great influence on flowering, self-fertilization and fruiting. Fleshy fruits contain seeds that maintain the diversity of the species. It is of real socio-economic importance, capable of providing a production of fruit consumed fresh or in the form of low-processed products (preserved chilli pepper, dried chilli pepper, spice, etc.) of high nutritional value essential for the survival of farmers. The study of the germination of four varieties was carried out respectively for Piquillo Pepper, Greek Pepper, California Wonder Pepper and Peperone quadrato d'asti Rosso. It begins with imbibition and ends when the percentage of water accumulated in the seed albumens of the four varieties reaches 0.362%, 0.370%, 0.364% and 0.372%, with penetration of the tegument. The latency time for all varieties is long. It is influenced by the albumen mass of the seed and by a slight tegumentary dormancy. A description of the plant of its above-ground and underground parts has been made. The determination of the amount of chlorophyll present in the cotyledonary leaves (playing an important role in the early development and growth of the seedling before the formation of true leaves) of the 4 varieties is different according to the varieties, it is 1.2; 3.6; 1.7 and 1.2.

Abstract
Capsicum annuum is among the five domesticated species: Capsicum (frutescens, annuum, baccatum, chinense and pubescens) the most cultivated in the world. It adapts quite well to dry and hot environments. Environmental conditions have a great influence on flowering, self-fertilization and fruiting. Fleshy fruits contain seeds that maintain the diversity of the species. It is of real socio-economic importance, capable of providing a production of fruit consumed fresh or in the form of low-processed products (preserved chilli pepper, dried chilli pepper, spice, etc.) of high nutritional value essential for the survival of farmers. The study of the germination of four varieties was carried out respectively for Piquillo Pepper, Greek Pepper, California Wonder Pepper and Peperone quadrato d'asti Rosso. It begins with imbibition and ends when the percentage of water accumulated in the seed albumens of the four varieties reaches 0.362%, 0.370%, 0.364% and 0.372%, with penetration of the tegument. The latency time for all varieties is long. It is influenced by the albumen mass of the seed and by a slight tegumentary dormancy.

Abstract: (french)
Le Capsicum annuum est parmi les cinq espèces domestiquées: Capsicum (frutescens, annuum, baccatum, chinense et pubescens) le plus cultivé dans le monde. Il s'adapte assez bien, au milieu sec et chaud. Les conditions environnementales ont une grande influence sur la floraison, l’autofécondation et la fructification. Les fruits charnus contiennent des graines qui assurent le maintien de la diversité de l’espèce. Il est d’une réelle importance socio-économique, capable, de fournir une production de fruits consommés frais ou sous forme de produits peu transformés (piment conservé, piment séché, épice, etc.) de valeur nutritive élevée indispensable à la survie des paysans. L’étude de la germination de quatre variétés a été réalisée respectivement pour le Piment piquillo, le Piment grec, le Poivron california wonder et le Peperone quadrato d’asti Rosso. Elle débute par l’imbibition et se termine lorsque le pourcentage d’eau cumulée dans les albumens de graines des quatre variétés atteigne 0.362%, 0.370 %, 0.364% et 0.372 %, avec percée du tégument. Le temps de latence pour toutes les variétés est long. Il est influencé par la masse d'albumen de la graine et par une légère dormance tégumentaire. Une description de la plante de ses parties aérienne et souterraine a été réalisée. La détermination de la quantité de la chlorophylle présente dans les feuilles cotylédonaires (jouant un rôle important au début de développement et croissance de la plantule avant la formation de vraies feuilles) des 4 variétés est différente selon les variétés, elle est de 1.2; 3.6; 1.7 et 1.2.
Author Keywords: Albumen, Chlorophylle, dormance, feuille cotylédonaire, graine.
