摘　　要：以‘蓝蝴蝶’‘音箱’‘紫褐’3个鸢尾品种的花粉为试材,采用单因素试验设计方法,研究了自然生长状态下鸢尾花粉的活力变化情况,同时探讨了不同贮藏条件和贮藏时间对花粉生活力的影响,以期筛选出不同类鸢尾的花粉贮藏技术,为提高鸢尾杂交效率奠定理论基础。结果表明:随着鸢尾开花时间的延长,‘蓝蝴蝶’‘音箱’‘紫褐’的花粉活力均呈现出先上升后下降的变化趋势,分别在开花后2、6、6h达到最大值88.12%、62.80%、34.97%。低温和干燥均有利于3个鸢尾品种的花粉贮藏,且变色硅胶为最适干燥剂、最佳温度为-18℃。以花粉活力≥20%为标准,‘蓝蝴蝶’‘音箱’‘紫褐’的花粉可分别贮藏17、14、7周。Pollens of Iris tectorum,Iris‘Muisic Box＇and Iris cv.were used as test materials.Using single-factor analysis method,this study investigated the changes of pollen viability in natural growth condition,meanwhile,the effects of different storage conditions and time were also discussed to explore different Iris pollen storage technology.This experiment laid the theoretical foundation for improving Iris hybridization efficiency.The results showed that,pollen viabilities of Iris tectorum,Iris‘Muisic Box＇and Iris cv.increased first and then decreased with extension of flowering time,and respectively after 2hours,6hours,6hours reached maximum of 88.12%,62.80%,34.97%.Low temperature and dry condition were suitable for pollen storage,the silica gel was the best desiccant and the best temperature was-18 ℃.Taking 20% as the standard,the pollens of Iris tectorum,Iris‘Muisic Box＇and Iris cv.could respectively be stored for 17,14,7 weeks.
