乙烯利用于禾谷类作物防止倒伏、提高作物产量方面已有报道,但对禾谷类作物分蘖和产量构成的影响意见不一,有人认为这与作物种类、采用品种特性、乙烯利喷施时期和施用量有关.为了明确上述观点的正确性,K.R.Foster等人1988-1989年利用3个不同分蘖特性的大麦品种Klages(强)、Leduc(中)和Bonanza(弱)在加拿大的Lacombe,AB进行了喷施乙烯利对灌溉春大麦分蘖和产量影响的研究.乙
Ethylene is used in cereal crops to prevent lodging and increase crop yield. However, it has different opinions on the tillering and yield components of cereal crops. Some people think this is not in accordance with the crop type, the characteristics of varieties, the duration of application of ethephon, In order to clarify the correctness of the above point of view, KRFoster et al. Conducted three larvae of Klages (barley), Leduc (middle) and Bonanza (weak) in Lacombe, AB of Canada with three different tillering traits from 1988 to 1989 Effects of spraying ethephon on tillering and yield of spring barley in irrigation
