测定种子发芽率和发芽势是苗圃生产、科研和教学上的一个重要环节,而种子发芽装置在苗圃生产、科研和教学中是必不可少的设备之一。过去,我系在园林苗圃种子发芽试验课中,一直使用耶可勃逊发芽装置。1980年我们从辽宁省辽中县林业机械厂购进一台我国自行设计制造的最新种子发芽装置—ZF-32型光照发芽器(此产品系该厂和中国林业科学研究院共同研制成功的)。为了鉴别ZF-32型光照发芽器在试验课中的使用性能,我们于1980年春天使用这两种发芽装置进行了园林树木种子的发芽试验比较。一般说来,测定种子发芽势所用的实际天数是否与测定发芽势所规定的天数相符合(即发芽装置是否为种子发芽创造最合
Determination of seed germination rate and germination potential is nursery production, research and teaching an important part of the seed germination plant in nursery production, research and teaching is an essential device. In the past, I used the Gerber’s germination device in the sprout trials of garden seed nurseries. In 1980, we purchased a new-type germination device-ZF-32 light germination device designed and manufactured by our country from Liaoning Province Central Liaoning Forestry Machinery Factory (this product was jointly developed by the plant and the Chinese Academy of Forestry) . In order to identify the performance of the ZF-32 light germinator in the experimental class, we compared the germination test of the garden tree seeds using the two germination units in the spring of 1980. In general, the actual number of days used to determine the seed germination potential is consistent with the number of days determined by the determination of the germination potential (ie, is the germination unit the most suitable for seed germination
