Abstract:
Pear belongs to the cross-pollination plant，it mainly relys on artificial pollination in the production，to explore the influencing factors of pear pollen germination，this experiment selected different varieties of pear pollen，and the condition(sugar，pH，physiological active substances，and other conditions) of pollen germination in different temperature were observed.The results showed that the outside conditions obviously effected the germination of pear pollen，pear pollen germination and pollen tube growth was the most suitable conditions for 150 g·L-1 PEG，150 g·L-1 sucrose,1 g·L-1 sodium fomate，0.1 mg·L-1 pectinase，pH 6.5，culture temperature kept at 25 ℃ or so，under the condition，the pear pollen had the highest germination rate.
