Abstract:
Wheat(Triticum aestivum) seeds treated with Gibberellic Acid have shown an increased germination rate and an initial accelerated seedling growth. Potassium plays an important role in the activation of growth related enzymes in plants. A study was conducted to evaluate the effects of GA3, potssium, water, and combined GA3 and potassium on the growth rate of wheat seedlings during their
heterotrophic phase. This triplicate study contained four treatments(n=12). Wheat seeds were placed on filter paper disks soaked in four stock solutions representing the four treatments. There was no difference in seedling growth rate when water alone and potassium stock solution were applied. Both GA3, and combined GA3 and potssium stock solutions equally increased the seedling growth rate when compared with the two foregoing treatments.
