Abstract

Post-harvest chemical treatment of cane stubbles during frosty period revealed that low temperature induced desiccation of subterranean buds, besides retarding nitrate reductase activity, protein synthesis and sprouting of buds under control, thereby creating a type of pseudo-dormancy in most of the buds. The adverse effects of low temperature stress were significantly mitigated with the application of ethrel 0.05%+emisan 0,25%+ gamma BHC 0.4%+urea 4.0% on the stubbles, immediately after harvesting of cane crop of an early maturing cultivar CoJ 64 during low temperature period. Accordingly, the productivity of ratoon crop was enhanced to the extent of 28% over control. The treatment could be exploited in the cultivation of sugarcane ratoon under such an environmental strategy.
