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.
