Biopriming with Trichoderma on Germination and vegetative characteristics of sweet corn, sugar beet and wheat
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...

| Summary: | 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. |
