Abstract

In pot experiment, groundnuts cv. ICGS-1, ICGS-5, ICGS-11, ICGS-44, ICGS-76, ICG (FDRS)-55 and Girnar-1 were water stressed at the flowering stage for 4 d. Water stress increased stomatal diffusive resistance and proline content and decreased transpiration rate, total chlorophyll, carotenoids and polyphenol contents. It was suggested that groundnut plants tend to adapt to water stress by decreasing tissue dehydration. The better performance of cv. ICGS-11, ICGS-44 and Girnar-1 under water stress was related to good stomatal conductance and increased proline level for osmotic adjustment
