Abstract:
Plant growth regulators either synthetic or natural have been found great and wide application in increasing the crop production or when applied in small amount, they bring rapid changes in the phenotypes of the plant and also influences the plant growth, right from seed germination to senescence either by enhancing or by stimulating the natural growth regulatory system. In view of their wide spectrum effectiveness on every aspect of plant growth, even a modest increase of 10-15% could bring about an increment in the gross annual productivity by 10-15 million tonnes. The Plant growth regulatorss (PBRs) have various economic importance in agricultural field. In vegetable growing, growth regulator also become more popular for seed soaking, inflorescence spraying, producing hybrid seeds and making seeds resistant to pest and diseases. Thus, growth regulators improve seed germination power, resistant power against disease and unfavorable growth conditions, increase and produces yield earlier and therefore, the yield become more qualitative and quantitative. Hence, advances in PBR technology will likely to be achieved through a better understanding of the mechanisms responsible for developmental processes and a more comprehensive description of the specificity of substances in mediating key biochemical steps. So, their importance has been boon and advantageous for farmers and horticulturists due to whom they took advantage to earn by the practical implication of these hormones and growth regulators.
