Role of Calcium in Plants:- Calcium is an essential plant nutrient. It has many roles:
- Participates in metabolic processes of other nutrients uptake.
- Promotes proper plant cell elongation.
- Strengthen cell wall structure – calcium is an essential part of plant cell wall. It forms calcium pectate compounds which give stability to cell walls and bind cells together.
- Participates in enzymatic and hormonal processes.
- Helps in protecting the plant against heat stress – calcium improves stomata function and participates in induction of heat shock proteins.
- Helps in protecting the plant against diseases – numerous fungi and bacteria secret enzymes which impair plant cell wall. Stronger Cell walls, induced by calcium, can avoid the invasion.
- Affects fruit quality.
- Has a role in the regulation of the stomata.
