马挂木种子发芽试验简报

对马挂木鲜种子和砂藏咱子进行变温或恒温、浸种呈不浸种等不同处理的室发芽试验，以及砂藏、干藏和不经贮藏而采用早播等马挂木种子的场圃发芽试验表明：测定调制好的鲜种子发芽率必需进行变温浸种处理，有胚种子的萌发效率达８０％左右，良芽率基本一致，测定砂茂个种子发芽率，不为温或中与否，萌发效率基本相同，为８５％左右，因此可按常规方法测定即可，马挂木种子在播种前腚经２个月砂藏处理，方法简便，效果明显，不仅有胚种

Preliminary Report on Seed Germination of liriodendron chinense

Germination experiment in door of fresh and sand stored liriodendron chinense seed treated by Changing temperature, constant temperature, seed soaking and nonsoaking,etc, germination test in nursery with sand stored. dry stored or early sowing without storage seed resulted that determination of germination efficiency of fresh seed which should be treated by changing temperature and seed soaking demonstrated 80% of endosperm seed.The germination efficiency was similar with that in nursery. Determination of germination efficiency of seed stored 2 months in sand could follow the old routine. The germination rate was 85% similar of treated by changing temperature and seed soaking- Lirodendron chinen se seed treated by 2 months storage in sand before sowing had germinahon rate of 89% with endosperm sed, and had an even emergence of seedling-
