在这项工作中，我们提出的证据表明，在小麦旗叶和穗上，由乙烯的产生（缩短籽粒灌浆期和降低籽粒重量）引起的干旱胁迫综合征，可以通过应用自由基清除剂苯甲酸钠或乙烯合成抑制剂氨基乙氧基乙烯甘氨酸来逆转。通过浇水补充水分也减轻了水分不足的有害影响。结果表明，灌浆期延长，籽粒重增加，总蛋白质含量高于定期浇水植株。
In this work we present evidence that the drought stress syndrome in the flag leaves and ears of wheat plants, provoked by the production of ethylene (shortening the grain filling period and lowering the grain weight) is reversed by the application of a free radical scavenger, sodium benzoate or the ethylene synthesis inhibitor, aminoethoxyvinylglycine. Rehydration by watering also attenuated the detrimental effect of the water deficit. Consequently, the grain filling period was longer, the grain weight increased, and the total protein content was higher than that in plants watered regularly.
