君袖苹果种植后有一个相对较长的不结果期,降低了其经济效益。加拿大奎尔夫大学的研究人员研究了乙烯利对君袖苹果幼树开花、早期产量和营养生长的影响。结果表明,早夏施用乙烯利显著促进了施用后次年苹果树的开花量,供试高浓度或重复施用效果更显著。乙烯利处理后君袖苹果(嫁接于M9砧木上)每株树上的花簇数量提高到
Jun-sleeved apple has a relatively long non-fruiting period, reducing its economic benefits. Researchers at the University of Quelph in Canada studied the effects of ethephon on the flowering, early yield and vegetative growth of young-sleeved apple-sleeved apple trees. The results showed that the application of ethephon in early summer significantly promoted the flowering of apple trees the next year after application, and the effect of high concentration or repeated application of the test was more remarkable. After the ethephon monarch apple (grafted on the M9 rootstock) the number of clusters per tree increased to
