| 摘 要： | 以新疆主栽扁桃8个品种和10个杂交组合为对象,研究其自交以及杂交组合的花柱离体培养花粉管的生长情况,花柱蛋白浓度对不同品种花粉的萌发生长抑制作用的影响,并分析其对扁桃自交不亲和性影响的强度差异。结果表明:在花柱1/3处的花粉管数量差别较小,而在花柱1/2处花粉管数量显著不同。花柱蛋白在低浓度下对花粉萌发和伸长没有抑制作用,蛋白浓度超过2.0μg/μL时才发生轻微的抑制作用,并且随蛋白浓度的升高抑制作用增强,表明高浓度的花柱蛋白比低浓度的花柱蛋白更能诱导不亲和的发生。

| Abstract: | Study on 8 breed and 10 cross-fertilize composes in almond.The growth situation of pollen tube by style isolated culture of self-fertilize and cross-fertilize composes.The results showed that the difference of pollen tube number in 1/3 of style between appetency and un-appetency varieties composes was insignificant,but the difference in 1/2 of style was evident.However the number of pollen tube number in 1/2 of style could not distinguish appetency and un-appetency composes strictly.So number of pollen tube... |
