对引种在苏州的9个路易斯安娜鸢尾品种的自交结实性、种子出苗率等进行观察测定。结果表明:人工辅助授粉阶段气温保持在25～30℃,结实率较高,但品种间有差异;用1g/L高锰酸钾溶液对种子进行20min处理能显著提高种子当年的出苗率与总出苗率;人工辅助自交授粉获得的种子比天然结实的种子出苗率高;‘Noble Moment’品种种苗白化苗率达8.69%,3个品种白化苗率1%以下,其余品种无白化苗。
The self-fertility and seed germination rate of 9 Louisiana iris cultivars introduced in Suzhou were observed and measured. The results showed that the temperature during the artificial pollination was kept at 25-30 ℃ and the seed setting rate was high, but there was a difference among varieties. Treating seeds with 1g / L potassium permanganate solution for 20 minutes could significantly increase the seedling emergence rate and the total The seed germination rate of seedlings of Noble Moment was 8.69%, the percentage of albino seedlings of three cultivars was less than 1%, and the rest varieties did not have albino seedling.
