Regulation of chloroplast development and function by ...

A role of the plant hormone cytokinin in regulating the development and activity of chloroplasts was described soon after its discovery as a plant growth regulator more than 50 years ago. Its promoting action on chloroplast ultrastructure and chlorophyll synthesis has been reported repeatedly, especially during etioplast-to-chloroplast transition.

Plant Growth Regulator Use in Apples (A3524)

Plant growth regulators (PGRs) can be used with some preci-sion for thinning fruit, regulating growth and adjusting harvest periods for apples. These products are absorbed by plant cells, primar-ily through the leaves and fruit, where they interact with the bio-chemical “machinery” of the plant. They work by mimicking naturally

Role of Growth Regulators and Phytohormones in Overcoming ...

Phytohormones, also termed as plant growth regulators, are chemical molecules that are produced elsewhere and translocated to various parts, which may function either locally or in distant tissues differing the actual site of synthesis. They act as a chemical messenger often controlling every aspect of plant life, majorly growth and development.
