CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Abscisic acid (ABA) is a stress hormone that accumulates under different abiotic and biotic stresses. A typical effect of ABA on leaves is to reduce transpirational water loss by closing stomata and parallelly defend against microbes by restricting their entry through stomatal pores.

Detailed explanation-2: -Abscissic acid is a mildly acidic growth hormone which functions as a general growth inhibits by counteracting other hormones or the reactions mediated by them. ABA induced bud dormancy, seed dormancy, closure of stomata and stoppage of cambial activity.

Detailed explanation-3: -However, abscisic acid (ABA) is the only hormone known to induce and maintain seed dormancy.

Detailed explanation-4: -Abscisic acid (ABA) is an important phytohormone regulating plant growth, development, and stress responses.

Detailed explanation-5: -Abscisic acid (ABA) is a plant hormone involved in the response of plants to reduced water availability. Reduction of guard cell turgor by ABA diminishes the aperture of the stomatal pore and thereby contributes to the ability of the plant to conserve water during periods of drought.
