Changes in Growth Physiology of Vigna unguiculata in Hydroponic System

Abstract

The excessive use of synthetic fertilizers and pesticides in agricultural practices has resulted in alteration of soil pH and decrease in soil fertility. Growth and development of healthy and high yield plants is difficult in less fertile and polluted soils. Therefore, researchers have developed soilless macropropagation methods which can increase growth and yield of plants in controlled environmental conditions. Soilless macropropagation involves use of desired nutrient solution for development of plants and a supporting medium. In present studies, an attempt was done to optimize growth of Vigna unguiculata plants in cellulose based sponge as supporting medium. Nutrient medium used for growth of plants was ¼ strength MS media. Influence of different hormones IAA (Indole 3 acitic acid), BAP (6-Benzylaminopuryne) and GA (Gibberellic acid) on growth physiology of plants at morphological, anatomical and cellular level was studied.
