Abstract

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.
