一、材料与方法紫椴(Tilia amurensis Ruprecht)种子具有种皮坚硬、致密、种仁含油量高,含水量少的特点,为打破长期休眠状态,人为地提供适宜的水分、温度、空气等条件,促进其提早萌动,完成萌芽前的准备阶段,我们用紫椴种子16市斤,其纯度为85%千粒重为36克,生活力为60%,为了比较采用不同种子处理方法所产生的不同效果,分别用雪藏、冷藏和变温处理三种方法作对比试验。其具体方法如下:
I. MATERIALS AND METHODS Tilia amurensis Ruprecht seed has the characters of hard and dense seed coat, high oil content of seed kernel and less water content. In order to break the long-term dormancy state, artificial seedlings are provided with appropriate moisture, temperature, air and other conditions , To promote its premature germination, to complete the preparatory stage of budding, we use Taring seeds 16 pounds, the purity of 85% of the 1000 grain weight of 36 grams, the viability of 60%, in order to compare the different effects of different seed treatment methods , Respectively, with three methods of snow storage, cold storage and temperature control for comparison test. The specific method is as follows:
