ABSTRACT

 

Mungbean is an important traditional legume crop of India. Salinity is serious problem for agriculture. The seeds germination was decreased linearly depending on salinity levels have recorded similar responses in different genotypes of mungbean. This corroborates further with the observation in Phaseolus also. The germination reduction could be due to imbalance in osmotic or ionic concentration rendering ionic toxicity, which varies from plant species to species. Germin ability indicates the establishment of seedling and crops production. The environmental condition is much important in the influctuation of gene during growth and development condition. The purpose of present investigation is to describe our work with regard to the dilution of the negative effect of salt stress on mungbean crops by use of growth regulator kinetin. The investigation was carried out by inducing salinity in pot culture with four controls and four under salinity NaCl@1000mM. Next eight pots are treated with two different concentration of kinetin under induced salinity.
