Maximizing productivity is vital but is not the decisive criterion in the seed production scheme. Maximizing quality is the basis of seed production for the upcoming storage program or to determine the next season's harvest. The quality is exaggerated due to indecent vegetative growth, environmental problems during seed development, accessibility of nutrients in the soil, etc. In the above, environmental stress is vital due to the additional interference of other factors. Environmental stress creates a barrier at different levels like before or after sowing, before or after flowering, before or during harvesting stages, etc. To limit the problem, various studies are underway through the application of treatments at different levels. These treatments can strengthen the source-sink association to improvise optimal seed quality in qualitative or quantitative terms. Therefore, decisive data on the developmental stages of seeds under stress are elements to evaluate the effects of various treatments. Say no to plagiarism.

Get an original essay The process of development or maturation of seeds is genetically controlled and involves a sequence of transformation from fertilization of the ovule to the creation of an independent unit where the environment plays a constructive role. role. But there was no coherent mechanism for understanding the maturation process because of its precise specificity to the cultural and environmental situation. Delouche (1971) specifies that the maturation process includes a series of morphological, physiological and biochemical changes from fertilization of the egg to physiological independence from the parent. Seed development from ovule fertilization to physiological maturity is classified into four phases (Dure, 1975 and Adams and Rinne, 1980), viz. cell division and expansion in phases I and II, accumulation of food mass in phase III, and increased seed moisture loss in phase IV. Maximum effort has been made in determining various seed maturation parameters on crop performance instead of establishing seed performance. The present research focuses on sampling seeds at predefined intervals of developmental stages related to specific seed characteristics in the maturation pathway. This approach identifies the seed based on its physiological maturity, quality, etc. during cultivation. Metabolic and structural association changes will ultimately indicate the production pattern in which a desirable genotype as well as environmental constraints both play key roles. Effort on this characteristic is insufficient, particularly in legume crops. In the new alluvial zone of West Bengal, the most common legumes are lentil (Lens culinaris Medik) and field pea (Pisum sativum L), which are a good source of dietary protein and energy. Field pea (Pisum sativum L.), native to Southwest Asia, was one of the first crops cultivated by humans (Zohary and Hopf 2002). It is a cool-season annual herbaceous crop in the family Fabaceae, grown in many parts of the world for its edible seeds. Pea is one of the oldest cultivated crops. European colonization introduced this culture to the New World and other parts of the world. According to statistics from..
