Experimental study demonstrates reduced seedling elongation and total protein levels in chickpea under cold stress, suggesting temperature-dependent and reversible growth inhibition.
In this study, shocks of cold at the levels of 5,3 and 1oC have been applied to the 6-days old chickpea (Cicer arietinumL.) plants. Next, having been left to grow for 72 hours under long day photoperiod circumstances 25oC, the length of their root and epicotyl have been measured at certain intervals. Moreover, the proteincontents of the plants exposed to low temperature shocks (1oC) have been indentified in connection with their controls. According to the results obtained, the low temperature shocks have prevented the length of the roots and epicotyl to a large extent. It is observed that the lower the temperature is, the more the plant's growth is prevented. It has also been observed that the cold sterss caused by the low temperature application might be reversible. The plants get rid of this stress later in low temperatures than in high ones. The low temperature application (1oC) has also considerably reduced the total protein amount.
