| description | The effects of the physical factors on dielectric characteristics of wheat biological parts were studied. Due to the sensitivity of phytochromes to the red light, the activity of the related enzymes as well as the inner energy and seed entropy during germination can be increased through irradiation He-Ne laser light to the plant seed with the wave length of 623nm, which, in turn, leads to the increased energy exchange between the seed and the environment. In this research, wheat varieties as Shiroudi, Zagros, Tajan and Kouhdasht were used under the He-Ne laser (623nm, 0.1 mW/mm-2) in time periods of 10, 15, 20, 25 and 30 minutes. Moreover, in order to investigation the radial effects of laser on the traits of the rootlet and the stemlet length on the fresh weight of stemlet and rootlet, number of seedlings, drought weight of stemlet and rootlet, and seed germination, four cultivars of wheat in five replication with factorial experiment as completely randomized design (CRD) have been studied. The results indicated that Zagros variety and Shiroudi variety had the fastest rate of seed germination, with 0.942(N/d) and 0.910(N/d), respectively. The result of this research indicates that cultivar Zagros with 0.006(grf), had he highest drought weight of rootlet among the cultivars. Also results showed that cultivar Zagros had more growth and drought weight of stemlet among the cultivars. |
