在叶部应用2—氯代乙基—(2—甲氧基,乙氧基)三聚硅烷(代号:CGA13586),由于它在叶上与水接触即释放出乙烯,能在小范围内导致油橄榄果实脱落。施用药剂以后7—8日发现果实在枝上的附着力降低到最低限度,这种作用的效果似乎直接在果柄离层组织上。药液的 PH 值能影响乙烯释放反应速率,PH 值较高其反应速率增加。较低的 PH 值(约为6)对促进果实脱落的作用更大,在 PH 值较高的情况下药剂可能水解太快,而乙烯释放后才能引起果实脱落。CGA13586与乙烯利[即2—氯乙基膦酸(Ethephon)]相比较具有相当高的乙烯释放效能,但持久力不长。
The application of 2-chloroethyl- (2-methoxyethoxy) tri-silane (code: CGA 13586) to the leaf, which releases small amounts of ethylene as it releases water upon contact with water on the leaf, Olive fruit fall off. 7-8 days after application of the agent, it was found that the adhesion of the fruit to the branches was reduced to a minimum, and the effect of this effect appeared to be directly on the detached tissue of the stalk. PH value of the liquid can affect the ethylene release reaction rate, the higher the PH value of the reaction rate increased. A lower pH (about 6) is more effective at promoting fruit loss, and at higher pH values the agent may hydrolyze too quickly, causing the fruit to peel off after ethylene is released. CGA 13586 has a relatively high ethylene release potency compared to ethephon [ie, 2-chloroethyl phosphonic acid (Ethephon)], but it does not last long.
