Plant Growth Regulating Chemicals II. [antikvár]

PREFACEThe need to increase the world food supply substantially by the end of this century poses one of the greatest challenges yet faced by man. Many agricultural scientists believe that this challenge can be met, and it is expected that plant growth regulators will play an increasingly important role in meeting this challenge.Plant growth regulating chemicals are used to modify crops by changing the rate or pattern or both of their response(s) to the internal and external factors which govern all stages at crop development from germination through vegetative growth, reproductive development, maturity, and senescence or aging, as well as post-harvest preservation.The purpose of this two-volume work is to make available both to the investigator and to the user, on a crop by crop basis, the latest information on the use of chemicals to regulate plant growth and development. Emphasis is given to the major crops and to those with which the most success has been achieved. Since the degree of practical success with each crop varies, primary attention is given to chemicals registered for specific use(s) with the particular crop discussed. Also included is information concerning chemicals not yet registered, but for which practical results are available. In some cases information concerning active compounds in the exploratory stages is included. Where known and pertinent, information concerning mode of action is included.The obvious classifications to use in presenting data on effectiveness of plant growth regulating chemicals are (1) by crop, (2) by chemical class, and (3) by plant function or process. Essentially all major summary or survey publications to date have been based on the plant function or process approach. This is primarily an academic approach and is not nearly as useful for practical purposes as a presentation by crops, as is done in this publication.
