Abstract
This study was designed to investigate the efficacy of the biocontrol isolates on growth promotion and ability in lowering the metal uptake by rice plant (variety MTU 7029) with two Trichoderma isolates namely MT-4 and UBT-18 both having tolerance towards cadmium. Substantial variations had been found in different treatments. Significant increase in chlorophyll was observed in Trichoderma treated plants at 25ppm stress. Total protein estimation in Trichoderma treated and non-treated rice plants under cadmium stress showed that protein content decreased significantly with increasing metal concentration in Trichoderma non treated plants. Trichoderma isolates helped in construction of significantly more protein with cadmium gradient. Peroxidase activity showed increasing trend up to 25ppm followed by gradual decline. The enzyme activity in Trichoderma treated plants was always lower compared to non-treated plants. In Trichoderma non-amended treatment, cadmium concentration in plant increased with increased in level of cadmium contamination which was equivalent with decreasing biomass of the plants. The cadmium uptake by rice plants increased with increasing cadmium contamination ranging from 6.66 to 6.99 µg g-1 plant biomass. The plant treated with Trichoderma on the other hand gained higher biomass which might be correlated with lower cadmium concentration in plants. It was observed that MT-4 treated plants contained lower cadmium coupled with higher biomass as compared to UBT-18.
