Demand for agricultural crop continues to escalate in response to increasing population and damage of prime cropland for cultivation. Besides, n pli ant tissue culture is traditional practice and have relevant importance. In addition, as energy becomes more difficult and costly to obtain, plant growth regulators will play an increasingly important role in energy conser­ vation as a result of increased yields due to their use.. Plant growth regulators like NAA at 10 to 50 ppm causes early flowering in pine apple. Growth & Development . Flowering can be delayed by 1 to 2 weeks NAA at 200 to 800 ppm application in apple, cherries, pears, peaches, and plums. Plants may be genetically deficient in a specific hormone (endogenous source) and respond to an external application (exogenous source). We also do this in our gardens. In modern agriculture, people have established the benefits of extending the use of plant hormones to regulate growth of other plants. Plant hormones are produced naturally by plants and are essential for regulating their own growth. They control the rate and extent of plant growth starting fromseed germination, after growth, flowering, fruit formation, ripening, wilting, falling of leaves, etc. Plant growth regulators are sprayed on plants to modify their growth and development. Role of Plant Growth Regulators in Vegetable Production: A Review P. Kaur 1* , D. Mal 1 , A. Sheokand 1 , Shweta 1 , L. Singh 1 and S.
