板栗种子具有两片肥厚的于叶,它是新的板栗植株幼小生命的营养来源。在现代的栽培措施中,为了利于苗期的集约管理,常先将种子催芽然后再进行播种。但发根稍长一点的种栗,在播种时,根很容易被弄断,这对种苗的出土是否会带来不利的影响呢?为此,我们进行了以下的实验(图1)。每种处理有20株幼苗。 Chestnut seeds have two hypertrophy leaves, which is the source of nutrition for the young life of a new chestnut plant. In modern cultivation measures, in order to facilitate the intensive management of seedling stage, the seeds are often germinated and then sown. However, when the root is slightly longer, the root can be easily broken when it is sowed. Does this have an adverse effect on the excavated seed? To this end, we conducted the following experiment (Figure 1). There are 20 seedlings per treatment.
