氯酸钾促进龙眼成花的应用及其机理

对某些果树进行催花诱导获得反季节水果生产具有重要的科研价值和现实意义。龙眼(D im ocarpuslong an Lour.)是我国南方重要的亚热带果树之一。近年来研究发现,氯酸钾可诱导龙眼树一年四季成花,有利于龙眼反季节生产。研究还发现,在不同的季节、采用不同的方法、对不同品种的龙眼树进行相同处理,催花效果均有一定差异。文章综述了近年来氯酸钾催花技术在生产领域中的应用概况,并对氯酸钾催花作用的生理及分子机制等研究进行了展望。

Review on applications and mechanism of KClO3 on inducing flower formation of Longan (Dimocarpus longan Lour.) trees

The induction of flower formation for some fruit trees to get off-season fruit is of great value in scientific research and practice significance.Longan(Dimocarpus longan Lour.) is one of the important subtropical fruits tree in the south of China.In recent years,the research found that KClO_3 could induce the flower formation of Longan trees in four seasons,so it is beneficial to the off-season production of Longan.Otherwise,with the same treatment,the effects of flower formation on different Longan varieties were different with different methods in different seasons.The applications of flower formation techniques of KClO_3 in production in recent years were summarized in the paper,and the research on the physiological and molecule mechanism of flower formation of KClO_3 was put forward.
