Transpiration and Guttation

Assertion: Waxy and cutin coating on plant parts reduce the transpiration.

Reason    : These adaptation are found in xerophytes.

Stomatal movements are influenced by a number of environmental factors. Which of the following statements is/are incorrect regarding this?

(i) Blue light keeps stomata open during the day promoting the movement of $K^{+}$ ions into guard cells.
(ii) Increased ${\mathrm{CO}}_2$ concentration reduces the pH of guard cells which promotes conversion of sugar into starch, ultimately causing closure of stomata.
(iii) Abscisic acid, under stress conditions, causes rapid movement of $K^{+}$ ions into guard cells.
(iv) Highly concentrated sucrose or salt solution when applied over to stomata, results in stomatal opening.
