| Abstract: | Plastochron index (PI) in two genotypes of cowpea (Vigna unguiculata L. Walp) showed a remarkable sensitivity to water stress. A linear expression PI = 4.6179 + 0.7451 S (r2 = 0.93) summarised the degree of sensitivity and predictability of PI to different stress levels (S). PI could be regarded as a stress sensitive trait in cowpea. |
