Symptoms Of Zinc Deficiency In Crops
When the crop is deficient in zinc, the growth is hindered, the plant is short, the growth of internode is seriously hindered, and the leaf vein is chlorotic or albino. New leaves are grayish green or yellowish white. The symptoms of zinc deficiency in vegetables are that internodes become shorter, plant growth is stunted, and leaves lose green. Some leaves can not be expanded normally, root growth is poor, and fruits are few or deformed.
1. Zinc can promote photosynthesis of crops
2. Zinc is the obligate activation ion of carbonic anhydrase in plant chloroplasts
3. Carbonic anhydrase can catalyze the hydration of carbon dioxide in photosynthesis
