分析了3个紫薇品种花粉活力及不同贮藏温度对花粉活力的影响,结果表明:3个紫薇品种鲜花粉活力存在极显著差别。低温有效地延长了花粉活力的保持时间,在4℃条件下,花粉活力保持164.278 h;在-20℃条件下,花粉活力保持141.278 h;在室温条件下,紫薇花粉活力仅保持18.444 h。
The effects of pollen vitality and pollen viability of three Lagerstroemia indica cultivars on pollen viability were analyzed. The results showed that there were significant differences in pollen viability between the three Lagerstroemia indica cultivars. Under the condition of 4 ℃, pollen viability maintained at 164.278 h; pollen viability maintained at 141.278 h at -20 ℃; pollen viability maintained at only 18.444 h at room temperature.
