Effect of growth regulators on biochemical attributes, grain yield and quality in pearl millet (Pennisetum glaucum L.R. Br.)

Abstract

The effect of foliar spray of brassinosteroid (BR), triacontanol, salicylic acid (SA), naphthalene acetic acid (NAA) and mepiquat chloride (MC) on pearl millet was studied. These growth regulators, increased chlorophyll, soluble protein, nitrate reductase activity (NRase) indole acetic acid oxidase activity (IAAO) and uptake of nitrogen (N). Grain yield, grain protein and sugar content were also enhanced by these growth regulators. Among the treatments, BR (0.1 ppm) and triacontanol (10 ppm) were found to be more effective.

Keywords: Pearl millet, Brassinosteriod, Triacontanol, Napthalene acetic acid, Salicylic acid, Mepiquat chloride, Soluble protein, Nitrate reductase activity, Indole acid oxidase activity
