获得种子垂直生长的初生根,可减少长度测量上的误差。这里介绍一种根据植物向地性生长的特性,设计的玻板直立发芽法。设备简单。(图1):用带盖板的方形或长方形的塑料盒做插置玻璃板的容器,在容器两侧备玻璃板的插座,各玻板之间有1—2厘米距离,玻璃板的大小由容器而定。备用滤纸与玻璃板等宽,长度略大于2倍。先将滤纸对折两半,在一半滤纸上再折2—3个约1厘米的小折,作放种 Gaining primary roots that grow vertically in the seed can reduce errors in length measurements. Here is a description of a plant according to the nature of the growth characteristics of the design of the glass plate upright germination. Equipment is simple. (Fig. 1): Place a square-shaped or rectangular plastic box with a cover on the glass-inserted container, and place the sockets on both sides of the container with a distance of 1-2 cm between the glass plates Depending on the container. Spare filter paper and glass width, length slightly larger than 2 times. First half of the filter paper folded in half on the filter paper 2-3 fold off about 1 cm for planting
