核桃发芽试验通常采用播种发芽法(即土壤发芽法),播种前种子需要预处理,费时,费事。这种方法不能适应生产和科研的需要。根据核桃“取胚方”试验和播种苗鉴定对比试验所得结果,作者认为“取胚方”是快速鉴定核桃种子发芽的好方法。现将试验方法及其结果介绍如下: 试验材料取自1978年秋于北京门头沟采收的核桃种子,分别进行“取胚方”发芽试验和塑料大棚苗床播种对比试验。
Walnut germination test commonly used sowing germination (ie soil germination method), pre-sowing seeds need pretreatment, time-consuming and laborious. This method can not meet the needs of production and scientific research. According to the results of the comparative experiment of walnut “taking embryos” and sowing seedlings identification, the author thinks “taking embryos” is a good method to quickly identify the germination of walnut seeds. Now the test methods and results are as follows: The test material taken from the autumn of 1978 in Beijing Mentougou walnut seedlings harvested, respectively, “take the embryo” germination test and plastic greenhouse planting seedbed contrast test.
