Abstracts

 

The objective of the paper was to evaluate the accumulation of proline content (µg/gFW) in two wheat varieties (Triticum aestivum L. var. KRL-1 and HUW 234) under different concentrations of NaCl stress. Also, evaluated the efficacy of proline accumulation in HUW 234 and KRL-1 under different NaCl concentrations by correlation, regression, anova, residual graphs, residual vs mean plot and matrix plot. The seeds were collected from IAS, BHU Varanasi. The seeds were grown in pots at controlled 12 light/12 dark, humidity (80%) and temperature (28±2ºC) conditions in growth chamber. The seeds were irrigated every day with water as control and NaCl solution as treatment (30-180 mM) and grown upto 60 days. The data was collected at the interval of 15, 45 and 60 days from germination for the analysis of proline accumulation in the varieties. It was observed that proline content accumulation increased steadly upto 150 and 120 mM after that less accumulation of proline has been observed in KRL1-4 and HUW234 wheat varieties respectively. It suggests that proline accumulation may be observed at the extreme condition of stress.
