High Temperature Significance of Anthocyanins Accumulation Stress Responses in Chickpea (Cicer Arietinum L.)
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 6, Issue 6
Abstract
A field experiment was carried to evaluate the chickpea genotypes for high temperature tolerance. High temperature stress was imposed by delaying sowing dates i.e. normal and late sowing date. Under late sown conditions, high temperature was experienced by crop starting from flowering stage to maturity. A significant variability was recorded in growth and yield. The late sown high temperature stress condition significantly reduced the crop yield parameters. The plants grown under high temperature conditions were observed for various morphological changes such as stunted growth, chlorosis, leaf tip burning, accumulation of anthocyanins and forced maturity. Under late sown conditions in genotype ICCV 92944 anthocyanins accumulation was observed in the basal part of the stem, branches and leaves while under normal sown conditions no such accumulation occurred, whereas in HC 5 there was no pigment accumulation was observed even under stress and normal conditions. The accumulation of anthocyanin has a positive relation with high yield in ICCV 92944. Under such conditions, accumulation of these pigments may be the reason in response to high temperature tolerance leads to the induction of antioxidant defense system.
