Key Concepts

Plant Hormones

Plant hormones, or phytohormones, are naturally occurring organic substances that, even in low concentrations, have profound effects on the growth, development, and responses of plants to environmental stimuli. They act as chemical messengers that regulate processes such as cell division, elongation, and differentiation.

Cytokinins

Cytokinins are a class of plant hormones known primarily for their role in promoting cell division, modulating growth, and delaying the aging (senescence) of plant tissues. They help maintain the vitality of plant cells by regulating processes that counteract the natural aging process of leaves and other organs.

Senescence

Senescence in plants refers to the process of aging, where cells and tissues gradually lose functionality leading to the degradation of chlorophyll and other cellular components. The inhibition of senescence, as achieved by certain plant hormones like cytokinins, is crucial for prolonging the functional lifespan of plant organs and ensuring continued growth and productivity.
