摘要
以宁夏地区茴香种子为试材,研究了不同种子灭菌方法、种子大小、浸种时间、浸种温度及催芽温度对茴香种子发芽特性的影响,旨在探求能够满足宁夏地区茴香种子最适宜的萌发条件。结果表明:用0.5%NaClO溶液处理40min种子污染率较低,且发芽率、发芽指数和活力指数较大,为最适宜的灭菌方法;直径为2～3mm的种子的发芽势、发芽率、发芽指数和活力指数均高于直径为1～2mm的种子;20℃避光浸种8h,25℃下暗培养催芽为宁夏地区茴香种子单果萌发的最适条件。
Taking fennel seed as material, the effects of different seed sterilization methods, seed sizes, soaking time, soaking temperature and sprouting temperature on the fennel seed germination characteristics were studied,in order to search the optimum environments for Ningxia fennel seeds germination. The results showed that,fennel seeds which were treated with 0. 5 G NaClO solution 40 min had the lower contamination rate and higher germination potential,germination rate, germination index and vigor index~ seeds as diameter 2-3 mm had higher germination potential, germination rate, germination index and vigor index than seeds as diameter 1-2 mm;soaking seeds under dark and 20℃ for 8 h,then accelerating sprouting under dark and 25℃ were the optimum germination conditions for Ningxia fennel seeds.
