Cadmium Toxicity Alleviation through Exogenous Application of Gibberellic Acid (GA3) in Mustard (Brassica juncea (L.) Czern.) and Rapeseed (Brassica rapa L.)

An experiment was carried out by considering adverse impact of heavy metals on human health through consumption crops. To alleviate the effects cadmium (Cd) toxicity foliar application gibberellic acid (GA3), two varieties Brassica including Indian mustard (Brassica juncea (L.) Czern.) commonly known as ‘Raya’ and rapeseed rapaL.) ‘Toria’ were studied. The Completely Randomized Design (CRD) used with eight treatments control in four replicates. Treatments following, T0 (control), T1 (150 μM CdCl2), T2 (50 mg/L GA3), T3 (75 T4 (100 T5 CdCl2 + 50 T6 75 T7 100 GA3). Gibberellic a plant growth regulator applied exogenously. concentration µM CdCl2) resulted Cd affected adversely morphological biochemical parameters. Foliar GA3 mg, mg mg) positively influenced various parameters root length (30 cm), shoot (129.75 number leaves (14.5), pods per (88) like total chlorophyll (0.19 mg/g), protein content (0.70 mg/mL), carbohydrates (0.37 mg/mL) CAT (0.56 units/mg). Outcome indicated that reduces harmful stress both varieties. It concluded all yield variety better compared to ‘Toria’, hence Raya recommended for large scale cultivation under stress.
