Effects of Gibberellic Acid under Cadmium Chloride Stress on Maize (Zea mays L.)

Abstract

Maize is very essential crop and positioned third in the globe after Triticumastivium and Oryza sativa according to the producing area. Cadmium is the metal that affects various grain crops and gibberellic acid is a useful hormone against a variety of stress. To determine the effect of GA and Cd, pot research was conducted in the OLD Botanical Garden Agriculture University Faisalabad. Two different types of corn were used (Neelam and Desimakai). The concentrations of cadmium chloride were (0 μM and 200 μM) and Gibberellic acid concentration (0mg and 0.25 mg) were applied. Stress was applied after every 10 days, and gibberellic acid was applied once in three leaves stage. After 60 days the plants were harvested. After this different growth, morphological and physiological parameters were evaluated. The investigation was carried out in a CRD with three replicates. The data will be checked statistically using computer analysis.
