要测定种子的发芽率,种子可以放在滤纸卷里催芽。我们曾在教学方面和在领导学生为集体农庄测定各种作物种子发芽率的有益社会工作时利用这种方法。在纸卷中催芽的方法如下:取滤纸小长条并对折为两重。正如我们的观察所表明了的,小粒种子的作物(车轴草、饲用粟)可用10厘米宽的长条,种子中等大小的作物(黑麦、荞麦)——20厘米宽,大粒种子(豌豆、玉米)——30厘米宽。将小纸条对折后,用普通铅笔沿折线划条线(图1)。
To determine the germination rate of the seeds, the seeds can be placed on the filter paper to induce germination. We have used this approach both in teaching and in helping social work leading students to measure the germination rates of various crop seeds for collective farms. In the paper sprouting method is as follows: take a small filter paper and fold into two. As our observations indicate, the seeds of small seeds (Ophiopogon japonicus, Fodder millet) can be cut with 10 cm wide strips, medium-sized seeds of medium size (rye, buckwheat) - 20 cm wide, , Corn) - 30 cm wide. After folding the small piece of paper, use regular pencil to scribe the line (Figure 1).
