不同贮藏方法对山桐子种子发芽的影响

Effect of Different Storage Methods on Seeds Germination of Idesia polycarpa

本试验以山桐子为材料,通过不同贮藏方式对山桐子种子进行贮藏,以研究不同贮藏方式对山桐子种子发芽的影响。结果表明:低含水量(5.40%)比较利于山桐子种子的贮藏,但是当种子含水量过低时(3.58%以下),会损害种子的发芽能力;用塑料袋贮藏山桐子种子时,4℃贮藏更优于自然温度贮藏;4℃湿沙贮藏效果最好,不仅可以维持,还可能提高山桐子种子的发芽能力,而自然温度干燥器贮藏效果最差,甚至会损害山桐子种子的发芽活力。贮藏时的包装材料(塑料袋和纸袋)以及是否在果实内贮藏对山桐子种子的贮藏效果影响不大。

Using Idesia polycarpa seeds as materials, Germination capability of seeds were studied after they stored in different storage methods. The results showed that low water content （5.40%） was beneficial to Idesia polycarpa seeds storage ,but too-low water content（ lower than 3.58% ）could impair the germination capability of seeds. Idesia polycarpa seeds wrapped with plastic bags, which were stored under 4 ~C, could keep better germination capability than under natural condition. Wet sand storage under 4~ was the most suitable way to store ldesia polycarpa seeds among 6 storage methods, because it could not only maintain the germination capability of seeds but also may promote it. Using dryer to store ldesia polycarpa seeds under natural condition was the worst way and it could damage the germination capability of seeds. However, packing material（ plastic bag and paper bag）used in storage made no influence on storage of ldesia polycarpa seeds. Moreover,whether Idesia polycarpa seeds were stored inside fruit or outside fruit,there would be a same result.
