Role of plant growth regulators in guava (Psidium guajava L.) cultivation: A review

Abstract

Guava is important fruit crop which is grown commercially in tropical and subtropical regions of the world. In India the productivity is low compare to other countries. Hence to overcome this, many technologies have been developed some importance were HDP, Meadow orcharding, crop regulation, use of improved varieties and hybrids and use of growth regulators. Among these technologies application of growth regulators plays an important role in all the stages of growth and development of cropwhich helps toimprove the final yield and quality of produce. The growth regulators are also used to improve theseed germination by breaking seed dormancy, root initiation in cuttings and air layers, to regulate proper canopy, flowering and fruit set. In this review article a detailed information on role of growth regulators in different stages of plant growth and development were given and also the research work was done in different countries on the role of various plant growth regulators in guava production have been incorporated.
