Study on pollen viability and stigma receptivity of 5 Iris plants / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To increase the reproduction efficiency of Iris plants.</p><p><b>METHOD</b>Pollen viability, stigmatic receptivity, the color of anther and stigma of 5 Iris plants were observed during blooming.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>The optimum artificial pollination time of these five species were 1200 -1400.</p>
