摘要:

为掌握芦笋杂交授粉最佳时间,选取3个性状优良、雌雄异株型芦笋品种,研究花粉活力和柱头可授性的变化规律。结果表明,不同品种的雄花花粉活力和雌花柱头可授性的变化规律有较大差异。取样时间段一定时,CA FCE2*M256和丰岛1号雄花的花粉活力在开花期2 d时达到最高。在自然开花当天,品种间花粉活力的日变化规律有较大差异:CA FCE2*M256在08:00达到最高值,Grande在16:00达到最高值,丰岛1号在12:00—14:00达到最高值。对于雌花的柱头可授性,品种间差异不显著,且均在开花期1 d时达到最高。由此可知,进行芦笋杂交育种时,应在适宜时间段选取一定开放程度雄花的花粉,对开花期1 d的雌花进行授粉,以获得较高的授粉成功率。

Abstract:

In order to accurately grasp the best time for cross pollination of Asparagus officinalis,the variation law of pollen viability and stigma receptivity of three Asparagus officinalis varieties with good character and dioecious type was studied. The results showed that there were great differences in pollen viability of male flowers and stigma receptivity of female flowers among these Asparagus officinalis varieties. When the sampling time was fixed,the pollen vitality of male flowers of CA FCE2*M256 and Fengdao 1 reached its highest at flowering stage 2 d. At the day of natural flowering,the diurnal variation of pollen viability was different among varieties:CA FCE2*M256 reached its highest value at 08:00,Grande reached its highest value at 16:00,and Fengdao 1 reached its highest value from 12:00 to 14:00. The stigma receptivity of female flowers showed no significant differences among varieties and reached its peak at flowering stage 1 d. It can be concluded that when Asparagus officinalis varieties are used for cross breeding,pollen from male flowers with a certain degree of openness should be selected at an appropriate time to pollinate female flowers at flowering stage 1 d,in order to achieve a higher success rate of pollination.

Key words: Asparagus officinalis, pollen vitality, stigma receptivity
