Role of osmolytes in maintaining water balance and photosynthesis under drought and heat in Chickpea (Cicer arietinum L.)

The present investigation entitled “Role of osmolytes in maintaining water balance and photosynthesis under drought heat chickpea (Cicer arietinum L.)” was conducted at Research Farm & labolatory Department Plant Physiology (Division Basic Science), Indian Institute Pulses (IIPR), Kalyanpur, Kanpur, Uttar Pradesh. During the rabi season 2015-16.The L.) various physiological traits which are essential for its adaptation to or limiting environments. Among those, osmotic adjustment is considered be one important conferring tolerance terminal drought. study aimed investigate role improving relation characteristics severe stress. 10 advanced breeding lines (ABLs) [C-7, C-8, C-9(M-51), C-11(M-86), C-16(M-55), C-19(M-93), C-20(M-39), C-21, C-214, C-235] derived from high low (OA) were used experiments. results showed varied degree OA test genotypes response variety Tyson Kaniva other along with yielding varieties DCP 92-3 (heat sensitive) JG 14 tolerant) both lacking as check improved when analysis done using chlorophyll fluorescence imaging. In addition higher retained greater retention subjected stress either field condition polyethylene glycol (PEG) 6000 induced solute accumulation leaves this proved play vital mining deep soil. experiment also positive combindly imposed.
