Interactive effects of UV-B radiation and salicylic acid on Vigna radiata L
2017
Bano, Chanda | Singh, N. B. | Sunaina,
The present study was conducted to investigate the physiological responses of Vigna radiata L. to UV-B radiation and salicylic acid (SA) alone and in combination. The exposure of the seedlings to UV-B radiation significantly reduced biophysical parameters. The pigments viz., chlorophylls and carotenoids and protein decreased while sugar content increased in the seedlings on UV-B exposure. UV-B stress increased the activities of superoxide dismutase, catalase and peroxidase. SA appears to mitigate the adverse effect of UV-B radiation on the growth and metabolism of Vigna seedlings.
