Abstract

Several physical methods including chemical methods were used as seed priming to enhance seed germination and crop yield. This research proposal explained the enhancement in the germination and growth rate of Tomato by applying laser irradiations and then examined how it affected the quality of seeds. Tomato seeds were irradiated by a semiconductor diode laser having a power of 5 mW. The germination percentage, growth rate, dries and fresh weight, average seedling length, and vigor index were investigated. The experiment was laid down according to the Complete Randomized Design (CRD) method with three replicates for each treatment. To determine the difference between various treatments of treated and non-treated seed an analysis of variance technique with a 5% confidence level of interval was used. The statistical results showed that with increasing laser radiation doses seed germination percentage and seedling shoot, and root length decreased. It was found that laser radiations affected several factors, including seed germination, growth rate etc. The best germination was noticed only in control plant samples as compare to treated seed. On the other hand, treated plant show more resistance against the disease and the environment stresses compare to control.
