Opis

This thorough book will give crop scientists and growers the latest information on several growth regulators, or phytohormones, that are used to improve the growth and yield of plants. Examining new approaches, such as molecular genetics, to investigate hormone root physiology, this guide will help you improve the yields of important crops and increase the efficiency of specific plants.
