- 摘要:
- 梨树属于异花授粉植物，生产中主要依靠人工授粉，为探索影响梨花粉萌发的因素。试验选择不同品种梨花粉，在不同温度、糖、pH、生理活性物质和抑制剂等条件下，对花粉的萌发状况进行试验观察。结果表明:外界条件对梨花粉萌发存在明显作用，梨花粉萌发和花粉管生长最适宜条件为PEG 150 g·L-1、蔗糖浓度150 g·L-1、甲酸钠1 g·L-1、果胶酶0.1 mg·L-1、pH 6.5、培养温度保持25 ℃左右，在此条件下梨花粉的萌发率最高。
- 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.
