Why does Brassica napus "flower but not real"?

The phenomenon of "flowering but not realizing" in Brassica napus is a physiological disease caused by boron deficiency in the soil because it is very sensitive to boron. Boron deficiency will cause its anthers to shrink, pollen grains to develop abnormally, pollen germination and pollen tube elongation will be hindered, which will affect the fertilization, resulting in the capsules not inflated or deformed. The ovules in the pods will shrink and the normal kernels will not develop. Therefore, in the case of boron deficiency in Brassica napus L., symptoms of "flowering but not realizing" will occur, with less pods and no seeds, which will have a great impact on yield, and will be severely reduced.

Because boron has a significant impact on the development of crop reproductive organs, the lack of boron is not only extremely harmful to rape, but also causes similar physiological diseases to other crops. Boron deficiency can cause cotton buds without flowers, peanuts with shells without kernels, and spring wheat with no spikes. In addition, sugar beet is also very sensitive to boron, and when it is deficient in boron, its roots are susceptible to "heart rot."

Control measures: (1) Boron applied to the soil. Per acre with about 0.5 kg of borax is appropriate, but also with organic fertilizer or nitrogen, phosphorus, potassium and chemical fertilizer mixed application. (2) Boron spraying. The concentration of the borax solution is 02%, which is sprayed once in the later period of seedling growth and in the convulsive period.
