Abstract: (43 Views)
Physical treatments such as laser, gamma, and beta rays can act as effective factors in increasing the growth and germination of plants. In this research, the effect of different treatments including laser, gamma, and beta rays on germination, growth rate, seedling length, plant dry weight, leaf area, leaf number, and chlorophyll content of pot marigold were investigated. The results showed that seed treated with laser, gamma rays, and beta rays produced significant increases in germination, growth rate, seedling length, plant dry weight, leaf area, leaf number, and chlorophyll content. The number of days until germination under the influence of priming treatments decreased by almost 4 days compared to the control (10 days), which belongs to the three treatments of hydropriming (7.6), gamma rays for 5 minutes (5.6) and beta rays for 15 minutes (6.6). However, the highest percentage of germination belonged to seed treatment with gamma for 15 minutes and beta for 10 minutes, which seems to improve the germination speed is one of the reasons for the above responses. Despite the above results, laser treatment for 15 minutes produced the highest seedling length, which was not significantly different from gamma treatment for 15 minutes. Under greenhouse conditions, beta treatment for 15 minutes caused the maximum stem length, which was not significantly different from laser treatment for 15 minutes. These two treatments had the highest plant dry weight and leaf surface index. According to these results, laser and gamma treatment for 15 minutes and beta ray treatment for 15 minutes have the most improvement in the mentioned traits.
