荔枝花果发育生理和分子生物学研究进展

Research advances in physiology and molecular biology of flower and fruit development in litchi

摘要: 荔枝Litchi chinensis是原产华南且最具中国特色的果树，花果发育与荔枝产量和果实品质密切相关，是荔枝发育生物学最重要的研究内容。本文主要综述了荔枝花芽分化、果实脱落和裂果、果实品质(包括果实和种子大小、果皮色泽、糖酸代谢)形成生理和分子机制等方面的研究进展，并展望了未来的研究方向。

Abstract: Litchi (Litchi chinensis) is native to South China and is the most distinctive fruit crop in China. Flower and fruit development, which play decisive roles in litchi yield and fruit quality formation, are the main contents of litchi biological research. In this paper, we make an overview on the progress in understanding the physiological and molecular mechanisms of the flower bud differentiation, fruit abscission, fruit cracking and fruit quality (including fruit and seed size, pericarp color, sugar and acid metabolism) formation of litchi, and give the prospects of future research directions.
