This research was carried out to investigate the effect of using seed treatment bz Carboxin Thiram, Imidacloprid, polymer, GA3 and Trichoderma (Wild and Mutant with 250gy gamma rays) on Germination Rate, Final Germination Percentage, Seedling length and Vigor index performed at the Seed Technology Laboratory of Sugar Beet Seed Institute(SBSI). GA3 alone or with chemical treatments and Trichoderma in seed coating increased the germination. Seeds coated with 2g Carboxin Thiram, 2g Imidacloprid , 2g polymerand 1000ppm GA3 showed the highest percentage of germination (99%).The result showed that the use of polymer increased the germination percentage, vigor index and seedling length. Furthermore, application of seed treatment did not show any adverse effects on germination traits. On the other hand, the use of wild species of Trichoderma reduced germination traits. Reduced effect of seed coating by Trichoderma moderated with mutant species, but there was a germination reduction when compared to the control treatment.

The present study was conducted to investigate the effect of biopriming on a number of selected species of Trichoderma fungi (T. harzianum, T. viride, T. konigii, T. virens and T. atroviridae( on vegetative and morphological traits of seedlings from sweet corn, wheat and sugar beet. Also, the effect of gamma-mutation on Trichoderma genome and its effectiveness was investigated. The experiment was conducted with three levels of inoculation; control, inoculation with Trichoderma mutant and inoculation with Trichoderma wild type in a completely randomized design with three replications at the Nuclear Agriculture Research Institute, done. Germination percentage and length, weight and seedling traits were evaluated based on the ISTA method. The results showed that maize seed biopriming with formulation of Trichoderma species (wild type and mutant) had a superiority in dry weight and Vigor index than control, and in other traits it was also observed improvement. Germination of wheat treated Trichoderma was 100%. Seedling length increased, but other traits had no significant statistical difference. Treatment with Trichoderma fungi in sugar beet had no favorable effect on measured traits. Totally, the results showed that biopriming of seeds with Trichoderma fungi in wheat and maize improved plant growth parameters, especially in the stages of its establishment and its initial growth. but, this method is not generalizable for all plants and should be studied in detail.
