测定了冬小麦不同群体条件下主要生育时期不同器官的乙烯释放量,结果表明,乙烯的释放是存在于小麦各生育时期的一种普遍的生理现象,在不同蘖位的分蘖和不同部位的小穗、小花及同位叶片的不同发育阶段,其乙烯释放量存在着较大的差异:起身期退化分蘖明显高于其它优势茎蘖,拔节后迅速下降,高密度下这一过程有所推迟;劣势小穗和劣势小花高于优势小穗和优势小花;功能初期和正在衰老的叶片高于功能盛期的叶片。表明乙烯参与了小麦优劣势器官转化的调控过程。
The results showed that the release of ethylene was a common physiological phenomenon existing in different growth stages of wheat. The tiller at different tillering positions and the spikelets at different positions , Floret and the same position leaves at different developmental stages, there is a big difference in the amount of ethylene released: the onset of degradation of tillering was significantly higher than other advantages of stem tillering, decreased rapidly after jointing, high density this process has been delayed; disadvantage Spikes and inferior flowers were higher than the dominant spikelets and dominant florets; the early and aging leaves were higher than the functional leaves. That ethylene is involved in the regulation of wheat superior and inferior organ transformation process.
