The high levels of ethylene in plants are involved in a range of harmful effects, such as the senescence of plants and the rotting of fruits. A series of novel oxime ethers were synthesized to counteract the ethylene effects. Their structures were characterized by IR, MS, and 1H NMR, and their effects on the senescence of cut carnation flowers were investigated. The results show that all of the target compounds extended the vase life of cut carnation, especially for compound 3i, which prolonged the vase life of cut carnation flowers to about 11 days, nearly 75% longer vase life compared to the control groups. Most of them were more effective than AgNO3 and aminooxyacetic acid.
植物中乙烯的高水平参与了一系列有害影响,例如植物的衰老和水果的腐烂。合成了一系列新型的肟醚以对抗乙烯的影响。通过红外光谱(IR)、质谱(MS)和氢核磁共振(1H NMR)对其结构进行了表征,并研究了它们对切花康乃馨衰老的影响。结果表明,所有目标化合物都延长了切花康乃馨的花瓶寿命,尤其是化合物3i,使切花康乃馨的花瓶寿命延长至约11天,比对照组延长了近75%。其中大多数比AgNO3和氨基氧乙酸更有效。
