一、材料与方法木荷种子采自龙泉县凤阳山自然保护区,采种母树位于开阔的溪沟边,中龄。1980、1981年种子平均饱满粒分别为51％,62％,千粒重6.2—7.2克,含水量11.5—13.4％。 (一) 解除种子的休眠方法 1.恒温处理:每日发芽温度不变。 2.变温处理:用4个不同的变温发芽,即每日发芽温度由高低两个温度组成。如20—30℃、16—8小时,表示24小时中8小时为30℃,16小时为20℃。
First, materials and methods Schisandra Seeds collected from Fengyangshan Longquan County Nature Reserve, planting seed trees located in the open edge of the brook, middle age. The average seeds in 1980 and 1981 were 51% and 62% respectively, and the grain weight was 6.2-7.2 g and the water content was 11.5-13.4%. (A) to release seed dormancy method 1 thermostatic treatment: daily germination temperature unchanged. 2. Variable temperature treatment: with four different temperature germination, that is, the daily germination temperature from high and low temperature of two components. For example, 20-30 ° C for 16-8 hours means 30 ° C for 8 hours in 24 hours and 20 ° C for 16 hours.
