Effect of seed priming with plant growth regulators on physiological changes of Indian mustard (Brassica juncea L. Czern & Coss.)

Abstract

The investigation entitled “Effect of seed priming with plant growth regulators on physiological changes of Indian mustard (Brassica juncea L. Czern & Coss.)” was conducted during rabi season, 2016-17 at the Instructional Farm of Narendra Deva University of Agriculture & Technology, Kumarganj Faizabad (U.P.) in randomized block design with eight treatments, three replications and variety Narendra rai (NDR-8501).Various concentrations of GA3 (100ppm, 150ppm, 200ppm) and SA (50ppm, 100ppm, 200ppm) were taken along with untreated control. Seed was soaked before 6 hrs of sowing. Observations were recorded at 40, 60, 80 DAS and at maturity. Biochemical parameters like, chlorophyll content, in green leaves, oil content (%) in dry seeds were taken. Seed soaking of different concentrations of GA3 and SA influenced on all characters of mustard crop.
