东北地区早霜低温冷害造成的减产很严重,为了战胜低温冷害确保丰收,使用化学催熟药剂,是解决提早成熟、达到丰产优质的重要措施之一。我们应用放射性~(14)C-乙烯利进行示踪试验,以期搞清楚在用不同的使用方法时,乙烯利在植株体内的运转、分配和代谢及其对成熟过程中物质积累速度的影响,总结乙烯利对棉花
Northeast frost damage caused by low temperature chills is very serious, in order to overcome the chilling injury to ensure good harvest, the use of chemical ripening agents, is to solve the early maturity, to achieve high yield one of the important measures. We used radioactive (14) C-ethephon to perform tracer tests in order to clarify the effects of ethephon on plant turnover, distribution and metabolism and on the rate of material accumulation during maturation using different methods of use, Summary ethephon on cotton
