对棉花等作物、蔬菜及一些园林植物等22种进行了乙烯熏气处理试验。乙烯使植物的蕾、花、幼果、叶片等发生不正常的器官脱落现象,危害农作物的产量及影响工厂绿化的效果。棉花的蕾及幼铃对乙烯比较敏感,脱落率随乙烯浓度的增大及熏气时间的延长而增长,日令16天以上的棉铃对乙烯抗性强。叶片的抗性因叶令而异,幼嫩未伸展的叶片及趋向衰老的叶片对乙烯比较敏感,充分伸展的功能性叶片对乙烯抗性较强。乙烯易引起植物的形态异常,这一现象是现场诊断乙烯污染的有价值的指标。如棉花受乙烯侵袭后在蕾铃脱落之前先发生叶片下垂及花蕾苞片张开的现象。
Twenty-two kinds of crops such as cotton and vegetables and some garden plants were tested for fumigation with ethylene. Ethylene leaves plants, flowers, young fruits, leaves and other abnormal organ shedding phenomenon, endanger the yield of crops and plant greening effect. Cotton buds and young bell are more sensitive to ethylene, shedding rate increases with the increase of ethylene concentration and fumigation time increases, day-long cotton boll resistance of more than 16 days is strong. Leaf resistance varies with young, non-stretched leaves and leaves tend to aging more sensitive to ethylene, fully functional leaves extended resistance to ethylene stronger. Ethylene can cause plant morphological abnormalities, a phenomenon that is a valuable indicator of on-site diagnosis of ethylene contamination. Such as cotton by ethylene invasion occurred in the buds before falling off the buds and flower buds bracts open phenomenon.
