Abstract/OtherAbstract:
|
Low-temperature-induced biochemical changes in bud and root band zone of the sugar cane set suppress sprouting, which is responsible for drastic yield decline in ratoon crops. This study was undertaken to modulate these low-temperature-induced biochemical changes using potassium, zinc, and Ethrel to enhance the sprouting of buds at 5 and 10 degrees C. Potassium, zinc, and Ethrel led to 80, 50, and 40% improvement in bud sprouting at 5 degrees C, respectively. An increase in reducing sugars and a decrease in sucrose contents were recorded with treatment of potassium, zinc, and Ethrel. Acid invertase, adenosine triphosphatase, indoleacetic acid oxidase, and nitrate reductase in vivo activities were also enhanced. However, treatments led to a significant decline in indoleacetic acid, total phenols, and superoxide dismutase activity, which rendered the in situ toxicity buildup in sets at low temperatures. |
