Plant Growth Regulators in Agriculture and Horticulture : Their Role and Commercial Uses

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.

As agriculture becomes more mechanized and science increases the possibilities for using inputs to enhance production, the role of PGRs becomes more vital. Plant Growth Regulators in Agriculture and Horticulture provides agriculture professionals and researchers with the information needed to effectively tap these versatile resources to enhance crop production.

Through discussions of the “classical five” phytohormones--gibberellins, cytokinins, ethylene, abscisic acid, and auxins--and the growing number of nontraditional PGRs such as oligosaccharins and brassinosteroids, Plant Growth Regulators in Agriculture and Horticulture reviews past and present uses of PGRs in managing crop yield and offers some speculation on future directions.

Detailed discussions on the use of PGRs in, for example, grain, ornamental, and citrus crops, introduce readers to strategies for enhancing crop quantity and quality, for improving the postproduction quality of life of perishable plants, and for crop load management, respectively. The book also includes informative visuals, such as tables of common, chemical, and trade names of different commercially available PGRs; diagrams of various PGR processes; as well as before-and-after pictures illustrating the effects of PGRs.

Plant Growth Regulators in Agriculture and Horticulture is a comprehensive text covering the role of plant growth regulators in:

• root formation
• manipulating yield potential
• plant stress protection
• ornamental horticulture
• postharvest life of ornamentals
• manipulating fruit development and storage quality
• citriculture
• reducing fruit drop
• bloom-thinning strategies
  
  If the history of agriculture, which is over 10,000 years old, was condensed into a twenty-four-hour span, science-based plant breeding would be only about fifteen minutes old. Still, the role of PGRs in agriculture is modest compared to other agrochemicals, such as fungicides, herbicides, and insecticides. Plant Growth Regulators in Agriculture and Horticulture is an invaluable guide to the varied roles filled by PGRs in the attainment of higher-quality, better-yielding crops.
