To determine whether the fullness of the seeds is accurate or not based on 1000 grain weights?
The detection method of the seed plumpness is measured by the 1000-grain weight of the seed. When the seed count is used, the number of seeds used is measured by the instrument. The professional instrument is a seed particle counting instrument. But have you ever thought of using a thousand-seed weight to make a representative and accurate measurement?
The grain weight of wheat is 23-58 grams, grains per kilogram. However, one disease of wheat can increase the grain weight of wheat, which is wheat black embryo disease. When wheat is infected with the virus, the embryonic part produces black spots. If the infected area spreads along the abdominal groove and occupies a part of the surface of the grain, it will cause dark spots in the grain, making the wheat grain dark brown or black. The virus has occurred in most of the world's wheat areas, and it also occurs to varying degrees in most wheat areas in China. Through the use of a seed counting instrument and a balance measurement, it was found that the 1000-grain weight of wheat black-embryo at different altitudes was higher than that of non-black embryos. If the seed source was 1200 m above sea level, the weight of diseased grains increased by 11.3% compared with the appearance without diseases. The weight gain of 1400m was 7.0%, the weight gain of 1600m was 9.2%, and the weight gain of 1 800m was 8.8%. This will affect the accuracy of wheat plumpness measurement. At the same time, experiments were conducted on wheat seeds containing this virus through the use of a precision seed germination box. Black embryo disease not only severely affected the germination potential and germination rate of wheat seeds, but also increased the incidence of wheat germination with the increase in the grade of wheat black embryo disease. Seed height, seedling fresh weight, root length, root fresh weight decreased.
The virus will cause dark spots in the grains when serious, but there will be no effect on the appearance when it is mild. The effect of this kind of wheat grains on the germination rate, germination potential and emergence rate of wheat is not It will be very large, but there will still be influence. At the same time, the grain weight of wheat will increase. Is this seed a rich seed?
