EFFECT OF INDUCED MUTATION BY UV RADIATION ON COTTON GROWTH, SEEDS AND PROTEASE ACTIVITY

Abstract

The cotton has great economical value. The aim of this study to determine the variation in cotton by induced mutation. As cotton seed treated with ultraviolet rays and sodium azide, it has affected on germination of whole plant. The weight as control 1.34 g/boll, UV 1 hour 1.68 g/boll and UV 2 hours 1.82 g/boll measured from cotton plant. The protease activity also determined from aqueous extract of cotton seed as control 43.7 mg/ml, UV 1 hour 24.36 mg/ml and UV 2 hours 26.7 mg/ml respectively.
