Abstract

OBJECTIVE

To increase the reproduction efficiency of Iris plants.

METHOD

Pollen viability, stigmatic receptivity, the color of anther and stigma of 5 Iris plants were observed during blooming.

RESULT

  1. The highest pollen viability was in 4 hours after blooming; 2. The stigmatic receptivities of I. sichuanensis, I. leptophylla, I. lactea and I. goniocarpa were strong in 4 hours after blooming, while that of I. lactea var. chinensis was strong in 2 hours after blooming; 3. The color of anther could reflect the pollen viability, but could not indicate the viability level; 4. The stigma color could not reflect the receptivity of stigma.

CONCLUSION

The optimum artificial pollination time of these five species were 12:00 -14:00.

摘要

目的

提高鸢尾属植物的繁殖效率。

方法

在开花期间观察5种鸢尾属植物的花粉活力、柱头可授性、花药和柱头颜色。

结果

  1. 花粉活力在开花后4小时最高；2. 四川鸢尾、薄叶鸢尾、马蔺和长果鸢尾的柱头可授性在开花后4小时较强，而白花马蔺的柱头可授性在开花后2小时较强；3. 花药颜色可反映花粉活力，但不能表明活力水平；4. 柱头颜色不能反映柱头的可授性。

结论

这5个物种的最佳人工授粉时间为12:00 - 14:00。
