Abstract

Abstract: The effects of sucrose concentrations（A）, boric acid concentrations（B）, calcium nitrate concentrations（C）and temperature（D）on the pollen germination and growth of Zaosu pear in Vitro were studied by using the orthogonal design. The results show that the order of affecting pollen germination rate and pollen tube length of Zaosu pear was B>A>D>C. The optimum conditions for Zaosu pear pollen germination and growth are as the following, that is, 1.5 g/L sucrose, 0.2 g/L boric acid, 0.2 g/L calcium nitrate and the temperature of 20 ℃.

Key words: Zaosu pear, pollen germination rate, pollen tube length, orthogonal design
