化学和物理因素对兔眼越橘花粉萌发的影响

Effects of Chemical and Physical Factors on Characteristics of Germination and Tube Growth of Pollen in Vaccinium ashei

以5个兔眼越橘品种的花粉为试材,研究了温度、硼砂、硫酸锰、氯化钴、蔗糖和GA3等化学和物理因素对花粉萌发及花粉管生长的影响.结果表明：兔眼越橘品种间花粉的发芽率存在着明显差异;适宜的花粉萌发温度为25～28℃,温度过高或过低抑制发芽;GA3和硼砂、硫酸锰、氯化钴等化学物质可以影响花粉的萌发,但品种间反应差异很大.改善环境条件和化学处理是提高花粉萌发率的有效途径.

The effects of temperatures and treatments with Na2B4OT, MnSO4, CoCl3, sugar and GA3 on germination and tube growth of pollen in Vaccinium ashei were studied . There are differences among the concentrations in every treatment. Suitable temperature for germination of pollen is 25 - 28 %. The results show that chemical treatments may be a way of changing germination and tube growth of pollen in Vaccinium ashei.
