Effects of calcium deficiency in plants

Calcium deficiency occurs from time to time in plants, which not only affects yield, but also deteriorates fruit quality and is intolerant of storage.
When crops are deficient in calcium, the tips of new leaves, leaf margins are yellowed, narrow and small deformities form adhesion-like expansion, and leaf veins shrink. Mesophyll tissue is incomplete and accompanied by burnt edges. The terminal buds are yellowed or even withered, the root tip is necrotic, the root system is thin and weak, the root hair development is stagnant, the extension is poor, and the top of the fruit is prone to depression and black-brown necrosis.

 

Physiological role of sulfur

1. The composition of proteins and enzymes, and sulfur is also a component of many enzymes.
2. Participate in redox reactions. Promote plant metabolism.
3. The composition of certain volatile substances in plants, garlic oil and sulfur in Liliaceae onion and garlic are also components of mustard oil in cruciferous crops such as rape, radish, cabbage..
4. It can reduce the toxicity of heavy metal ions to plants.
