荔枝为亚热带特产名果,色艳味佳,营养丰富,在国内外市场享有很高的声誉.但生产上存在着花多实少(俗称“爱花不爱子”),因此,产量较低.过去曾认为主要是由于雌雄花期不遇的缘故.据观察,荔枝雌能花与雄能花期虽有不遇,但同一片果园中也经常存在着不同株或不同枝序的雌雄能花同期开放的现象.为了探明荔枝低产原因,我们拟从荔枝花粉发芽的条件及如何提高花粉发芽率进行研究,以期为提高荔枝产量采取人工授粉和其他农业措施提供依据.
Lychee is a famous tropical fruit of subtropical region with rich color and rich nutrition, enjoying a high reputation both in domestic and overseas markets. However, there are more and fewer fruits in production (commonly known as “Love and Love”), therefore, the output is low In the past, it was mainly because of the lack of flowering periods between male and female.It is observed that although the male and female flowering periods of litchi are not met, the male and female flowers of different branches or branches often exist in the same orchard Phenomenon.In order to find out the reasons for the low yield of litchi, we intend to study the conditions of litchi pollen germination and how to improve the germination rate of pollen, in order to provide the basis for improving litchi yield by artificial pollination and other agricultural measures.
