Effect of plant growth regulators on biochemical analysis of onion (Allium cepa)

Abstract

A field experiment was carried out during Rabi 2018 and 2019 at RHRS, Navsari Agricultural University, Navsari, Gujarat to study the effect of different plant growth regulators like GA3 and NAA on biochemical parameters of onion. The treatment T1 (GA3 25 mg l-1) recorded highest chlorophyll content of leaves 45 DATP (1.06 mg 100 g-1), 60 DATP (2.64 mg 100 g-1), 90 DATP (2.32 mg 100 g-1), ascorbic acid (10.45 mg 100 g-1), phenols (61.77 mg 100 g-1) and proteins (1072.54 mg 100 g-1) and found significant. The moisture content (83.98%) under T6 (NAA 75 mg l-1) were found significant.
