“…Similar effects were observed in our experiment after root application of T. atroviride to the Panicle Hydrangea roots. This method of application is much more effective than the foliar treatment used by Di Vaio et al [27], who did not observe increased growth of young olive trees cultivated in containers in a nursery. On the other hand, Rakibuzzaman et al [52] observed an increase in the dry weight of tomatoes after inoculation.…”

“…Trichoderma fungi are most commonly applied to soil and leaves. The latter method is more effective, especially in preventing soil-borne diseases [27]. However, these authors did not find any improvement in the growth of young olive trees grown in containers after the foliar application of the Trianum P biostimulant based on T. harzianum fungi.…”

The aim of this experiment was to assess how the interaction of two treatments influenced the growth and flowering of two varieties of Panicle hydrangea shrubs. The first treatment was plant pruning. Simultaneously, the plants received one of the three following treatments: root application of Trichoderma atroviride, root application of BlackJak biostimulant, or foliar application of a multi-component fertilizer. Simultaneous pruning and inoculation of the plants with the Trichoderma atroviride mycelium improved the length of hydrangea shoots the most, as compared with the control plants (18%). These two treatments also increased the number of flowers (16–47%, depending on the variety) and the fresh weight of plants (10–28%) compared with the control plants. T. atroviride alone improved the number of flowers in both varieties (19–24%) and the diameter of inflorescences in the ‘Silver Dollar’ one (17%). The foliar nutrition increased the fresh weight of plants by 7–57%, depending on the cultivar and pruning. It also increased the diameter and number of inflorescences in one of the varieties. Together with pruning, it intensified the growth of shoots in both cultivars (5–10%). The BlackJak biostimulant treatment gave ambiguous results. In combination with pruning, it improved the length of shoots (15%) in one cultivar and the fresh weight in the other (18%). Without pruning, the treatment increased the number of flowers (16%) and the diameter of inflorescences (9%) in one cultivar. It increased the fresh weight of plants in both cultivars (19–21%). Regardless of the other treatments, pruning increased the length of the shoots and the fresh weight of the plants. On the other hand, it reduced the number of flowers and their diameter. In most cases, the biostimulant treatment and foliar fertilization improved the growth and flowering of the plants. In combination with pruning, they improved the growth of the hydrangea shrubs but reduced the number and diameter of flowers. The simultaneous Ta treatment and pruning were the most beneficial for the growth and flowering of the panicled hydrangea plants grown in containers in a nursery.

“…Trichoderma strains exude SM in olive seedlings ( Olea europaea ), which increases height, leaf area, stem diameter, and seedling clearance in nursery conditions [ 79 , 80 ]. One of the most promising functions performed by secondary metabolites refers to the multiplication of plant cells, in which the action performed by Trichoderma strains correlated with higher rates of germination speed and germination percentages and factors for obtaining seedlings with high morphological and physiological parameters [ 81 ].…”

Forest production has great relevance in the Brazilian economy, characterized by several production sectors, including the production of seedlings. With the focus on maximizing the capacity of survival, development, and adaptation of seedlings, Trichoderma is highlighted as a potentially useful genus of microorganisms for promoting growth and higher product quality. In this sense, this review aims to describe the main mechanisms of fungi action in forest seedlings’ production. The different species of the genus Trichoderma have specific mechanisms of action, and the current scenario points to more advances in the number of species. The interaction process mediated by different mechanisms of action begins in the communication with plants, from the colonization process. After the interaction, chemical dialogues allow the plant to develop better because, from colonization, the forest seedlings can maximize height and increase shoot and root development. Fungi promote solubilization and availability of nutrients to seedlings, which show numerous benefits to the development. The use of beneficial microorganisms, such as fungi of the genus Trichoderma, has become a sustainable strategy to enhance seedling development, reducing the use of agrochemicals and industrial fertilizers.

“…These fungi improve plants' resistance to drought stress by increasing the volume of the root system and improving the nutrient and water acquisition [25,26]. Trichoderma is administered both to the leaves and to the soil, but the latter form of application is better in preventing soil-borne pathogens [27]. According to research [27], applying this fungus to the roots in nursery production has a significant effect on root colonization, which increases plants' growth and their resistance to biotic and abiotic stresses.…”

The conducted experiment evaluated the effects of three fungi—Trichoderma atroviride (Ta), Trichoderma harzianum (Th) and Phytium oligandrum (Po)—on the growth of maidens of two apple cultivars, ‘Szampion’ and ‘Topaz’, budded on two rootstocks, M.9 and M.26, in the nursery. The evaluation was based on the number of maidens obtained and their height, trunk diameter and number and length of lateral shoots, as well as the fresh weight of the leaves and the whole maiden. For the weaker-growing maidens of the ‘Topaz’ cultivar, the activity of the photosynthetic apparatus was additionally measured depending on the rootstock and fungal treatments. The number of maidens obtained improved significantly when Th (8.3–9.0%) and Po (8.4–12.8%) were applied, depending on the rootstock and cultivar used. With the best treatment with the Po fungus, on average, for the two cultivars, maiden apple trees budded on the M.9 dwarf rootstock were characterized by a significantly better height of 6% and trunk diameter of 13% compared to the control. In contrast, trees grown on the M.26 rootstock did not have significantly increased growth after the same treatments, with the exception of the Po fungus, which improved the stem diameter by an average of 10%. The use of fungi stimulated an increase in the number and length of the lateral shoots of maidens of the more easily branching ‘Szampion’ apple tree cultivar. Based on the fluorescence parameters obtained, it can be assumed that the ‘Topaz’ cultivar on the M.26 rootstock is less susceptible to stress conditions, especially those related to high temperatures and drought. All fungi used had a positive effect on the activity of the photosynthetic apparatus. Significantly worse values of the fluorescence parameters were obtained for the control combination compared to the fungal treatments.
