Relationship between Seed Grain Weight and Seedling Survival Rate

The survival rate of seedling seedlings is affected by the seed's clarity and germination rate. Moisture content and other effects, but people often overlook the seed's grain weight, in general, large seeds have a higher seedling vitality, seed weight is not impossible to carry out a particle to be called generally use the 1000-grain weight to measure, and in When measuring 1000-grain weights, balances and electronic counting instruments are used to operate.

The relationship between grain weight, root length, and shoot length was found to be significantly positively correlated with the length of roots, but not with shoot length. Under light conditions, grain weight was positively correlated with shoot length, but not with root length. Grain weight has a decisive effect on the fresh weight of the seedlings and on their reproduction. In the process of measurement, the major germination of the large-grained seeds was normal except that one or two of the seeds were rotten. The germination rate of small seeds is much lower.

Seed weight is one of the important factors affecting germination characteristics and seedling vigor, and grain weight has a profound impact on the growth of seedlings grown in the field. Large grain seeds with large differences in grain weight use seed germination power and germination rate to express seed vigor, which accurately reflects the actual field production capacity of the seed. Also consider the size of the seed particles.

The 1000-grain weight measurement of seeds can not be separated from the following balance and electronic automatic particle counting instrument, and the seed weight measurement can not be separated from the 1000-grain weight measurement. The 1000-grain weight measurement can not only understand the seed moisture content but also analyze the fullness of the seeds. At the same time, it can also be seen from the above that seed grain weight directly affects the survival rate of seedling seedlings, so the measurement of seed grain weight is even more important.
