Foliar Spray of Salicylic and Gibberllic Acid on Productivity of Crops: A Review

Plant growth regulators are chemical substances and when applied in small amounts, they bring rapid changes in the phenotypes of the plant and also the plant growth, right from seed germination to senescence either by enhancing or by stimulating the natural growth regulatory system. Plant growth substances are known to enhance the source-sink relationship and stimulate the translocation of photo-assimilates thereby helping in effective flower formation, fruit and seed development and ultimately enhance the productivity of crops. An attempt is made to review the some of the important growth substances like salicylic acid and gibberellic acid on growth and productivity of the crops.
