很多人认为杜仲的果皮和种皮是其发芽迟缓的主要原因。作者利用在苏联阿勃哈滋橡胶植物研究站和中国河北省采集的种子进行了试验,发现情况并不如此:种子浸泡7-9天后已充分膨胀,含水量几乎增加了9倍,并且小果类型的持水力比大果类型的要强。为了促进杜仲种子发芽和提高场圃发芽率,作者

Many people think that the pericarp and seed coat of Eucommia is the main reason for its slow germination. Using the seeds collected at the Abkhazia Rubber Plant Research Station in the Soviet Union and Hebei Province in China, the authors found that the situation was not the case: the seeds had been fully expanded 7-9 days after immersion, the water content increased almost 9-fold and the fruit size The type of water holding stronger than the type of fruit. In order to promote the germination of Eucommia seed and improve the germination rate of field nursery, the author
