The Effects of Varying Gibberelic Acid (Ga3) Levels on Germination and Seedling Growth in Different Wheat (Triticum Aestivum L) Varieties
- Abstract
-
Wheat (Triticum aestivum .L) is one of the most important crop in the world. Despite global advancement in farming technology, Zimbabwean farmers are still lagging in adopting new systems and the use of new products in wheat production. Gibberellic acid (GA3), an eco- friendly bio regulator that is widely used to enhance the productivity and phenotypic characteristics of multiple crops. A 4x4 factorial RCBD study was conducted at DR&SS to showcase the benefits of using Gibberellic Acid on germination and seedling growth of wheat. The study involved 4 different wheat varieties which were Dande, Runde, Save and Ncema and 4 different GA3 levels which were no GA3, 1ml, 2mls and 4mls, diluted with 2litres of water respectively. The parameters assessed were germination percentage, seedling vigour index, stem height, tiller number and leaf area index. Data collected during the experiment was subjected to statistical analysis of variance using GenStat package 18th Edition version and LSD at 5% level. The results indicated that varied levels of Gibberellic Acid affects different wheat varieties differently. The effective use of GA3 at 4mls is effective to the Save, Dande and Ncema varieties only the Runde variety proved to do well when 2mls of GA3 was applied. The application of Gibberellic Acid can, therefore, be used to enhance germination and seedling growth of wheat and hence combat food insecurity amongst communities of Zimbabwe.
