Seed germination potential measuring method

Abstract

The invention discloses a seed germination potential measuring method, and belongs to the field of plant culture. The method comprises the following steps that seeds are selected; the selected seeds are soaked for 24h by clear water; a 0.8 percent agar culture medium is prepared, namely the weighed agar powder is poured into distilled water, and the mixture is decocted until the agar powder is completely dissolved; the prepared culture medium is poured into a culture vessel; planting holes are dug out in the culture medium by a dropper; then, the soaked seeds are removed by a cleaned rubber head and are put into the planting holes; after sprouting, the root length is measured by a vernier caliper; calculation is performed according to the formula that the vitality index (GV)=germination index*seedling root length. When the method provided by the invention is used, the operation is simple and convenient; the seeds can also be enabled to be uniformly distributed in the culture medium; each seed is enabled to be in good environment; further, the measuring result accuracy is improved.

Description

technical field [0001] The present invention relates to a measuring method, in particular to a measuring method of seed germination potential. Background technique [0002] In some herbaceous plants, due to their short stature, short growth cycle, and easy operation, they are often used as experimental plants to study related technologies and theories in the field of botany, especially their short dormant period and fast germination, which are often studied by measuring the germination potential of the period Such as the allelopathic intensity of allelopathic substances, etc., at present, 0.8% agar method is basically used to plant seeds at home and abroad. During the cultivation process, because some plant seeds are small and have sticky substances on the surface after contact with water, they are easy to slip away when placed directly in the medium , leading to uneven distribution of seeds; if the seeds are buried in the culture medium by using tweezers, it is time-consumi...

[0002] In some herbaceous plants, due to their short stature, short growth cycle, and easy operation, they are often used as experimental plants to study related technologies and theories in the field of botany, especially their short dormant period and fast germination, which are often studied by measuring the germination potential of the period Such as the allelopathic intensity of allelopathic substances, etc., at present, 0.8% agar method is basically used to plant seeds at home and abroad. During the cultivation process, because some plant seeds are small and have sticky substances on the surface after contact with water, they are easy to slip away when placed directly in the medium , leading to uneven distribution of seeds; if the seeds are buried in the culture medium by clamping with tweezers, it is time-consuming and labor-intensive, and the conventional method is time-consuming and labor-intensive to measure the germination potential, the root system is bent, and the accuracy is difficult to guarantee
