◓ Process of transpiration is essential evil by Curtis. Process of transpiration is unavoidable by stewards.
◓ As a result of transpiration process cooling effect is produced on the surface of leaf.
[tex]\large{\underline{\boxed{\gray{\bf Stomatal\:Index = \dfrac{S}{S + E}\times 100 \%}}}} [/tex]
where S = number of stomata per unit area.
E = Epidermal cells per unit area.
◓ Transpiration has been classified into 3 types. Based on position where maximum amount of [tex]\sf H_2[/tex]O
O is lost :-
- (a) Stomatal transpiration (90%)
- (b) Cuticular transpiration (9%)
- (c) Lenticular transpiration (1%)
