This study investigated the varietal-specific impact of Trichoderma application on wheat germination, early growth, and biomass. The experiment was conducted within a controlled chamber, employing three distinct Trichoderma treatments with six replications: a coating application method applied by carboxymethyl cellulose, liquid application method, and a series of control groups, with each treatment applied to both sterilized and non-sterilized soil samples. The research concentrated on assessing how these Trichoderma treatments influence the germination process, early growth stages, and overall biomass of wheat plants. Seed germination in the Archashon wheat variety exhibited a decline when subjected to Trichoderma applications. In contrast to the control group, where seed germination reached approximately 77%, the application of Trichoderma in liquid form led to a remarkable increase in seed germination for the Cell wheat variety, with rates reaching as high as 90%. Similarly, the Shrek variety exhibited a parallel trend, further emphasizing the variety-specific impact of Trichoderma application on seed germination. While Trichoderma applications had a notable impact on plant height in the Archashon and Shrek wheat varieties, the Cell variety displayed remarkable stability in this regard, showing no significant shift in plant height in response to our treatments. Specifically, for Archashon and Shrek, Trichoderma applications were associated with a decrease in plant height. Regarding shoot biomass, no considerable change was observed in all varieties following Trichoderma applications. However, a very slight increase was noted after employing the seed sticking method. Finally, we measured root extrication biomass, and the data reveal a promising impact of Trichoderma application in terms of stimulating root growth of wheat plant. In conclusion, our initial experiment exhibited a promising impact of Trichoderma as a biostimulator. We are currently extending our research to real field conditions, and future data will provide a more comprehensive understanding of its practical application.
