荔枝胚胎发育研究进展

Research progress in embryonic development of Litchi

就我国园艺学者对荔枝胚乳与胚的发生、发育 ;胚与胚乳生长协调性与座果的关系 ;胚胎发育过程内源激素变化与外源生长调节物质对胚胎发育的影响 ;以及单性结实荔枝的胚胎发育与生长调节物质的关系等 4个方面的研究进展作了综述 ,从中了解荔枝不同类型品种与胚胎发育内在机制的关系 ,供荔枝育种、栽培的参考 ,并对今后的研究方向提出了建议。

The recent advances of the research on embryonic development of Litchi were reviewed as follow four aspects:the process of embryo and endosperm development of Litchi, the relationship between the growth harmony of embryo and endosperm with the rate of fruit set, the influence of endogenous hormone variation and ectogenous growth regulators on Litchi embryonic development,the relationship between growth regulators and embryonic development of parthenocarpy Litchi types. From above,the relationship between different Litchi varieties and the mechanism of embryonic development were suggested. Some suggestions for the future research direction were made.
