荔枝因裂果常使产量造成严重损失。一般认为,荔枝裂果是在果实成熟期间,因严热、干旱的天气而引起的。Prasad和Jauhari观察到低浓度(10PPm)的2,4,5—T和奈乙酸可以减轻裂果数量。本文研究目的是想查明乙烯利对荔枝裂果的影响和树体不同部位的裂果发生率。乙烯利浓度分别为:0.0,0.1,1.0, Litchi often cause serious damage to the production of fruit. It is generally believed that litchi cracking is caused by severe, dry weather during fruit ripening. Prasad and Jauhari observed that low concentrations (10 ppm) of 2,4,5-T and nalacetic acid can reduce the number of fissures. The purpose of this study is to find out the effects of ethephon on the cracking of litchi and the incidence of cracking in different parts of the tree. Ethephon concentrations were: 0.0,0.1,1.0,
