Why do rapeseed plants need boron supplementation? A detailed explanation of the role of boron nutrition

(Agricultural Wealth Network) Rapeseed requires more boron than other crops; when the boron content in the soil is below 0.4 mg/kg, boron deficiency will appear. When the soil is severely deficient in boron, rapeseed can develop the disease at the seedling stage and bolting stage, and diseased plants wither and die; when the soil is mildly deficient in boron, symptoms appear after the flowering stage, and diseased plants bloom but do not set seed. The boron content of the whole rapeseed plant is 16.8 mg per kg. After rapeseed flowers, boron accumulation increases sharply, and the relative boron content in flower buds and siliques is much higher than in vegetative organs, showing that rapeseed needs more boron during the growth and development stage of reproductive organs. At this time, the amount of boron has an important effect on the formation and development of reproductive organs.
