Positive Effect

The effect of Trichoderma harzianum and T. longibrachiatum in promoting plant growth was studied in acacia, alder, cypress, and eucalyptus. As variables associated with the growth and development of forest plants, the height, stem and root length, number of leaves and roots and fresh weight of the plants were evaluated. The two Trichoderma species used had a positive effect, improving most of the variables evaluated in all the forest species studied, demonstrating that this genus of fungi is a good alternative as plant growth promoters.

Soil Borne Fungi

The genus Trichoderma is multicultural soil-borne fungi found in different ecosystems. They are highly successful colonizers of their habitats. Genus Trichoderma is capable of dealing with various environments such as compost, agricultural soils, rhizosphere, and waste material. Therefore, different strains of Trichoderma have been applied in agriculture, bioremediation, waste management, and biotechnology. Many Trichoderma species act as biological control agents and plant growth promoters. Additionally, the genus Trichoderma is a new fungal source for the production of cyclosporin A as well as various hydrolytic enzymes with industrial importance.

New solutions allowing for the shortening of the growing cycle and improvements in plant quality are constantly sought in order to improve the efficiency of bedding plant production under covers. Biodegradable polysaccharides and their derivatives have become increasingly popular in horticulture as plant growth promoters. A greenhouse pot experiment was conducted to evaluate the effects of depolymerized gellan of different molecular weights (MW 56 kDa and 77 kDa) on the growth and physiological parameters of ornamental bedding plants Rudbeckia hirta L., Salvia splendens Sellow ex J.A. Schultes, Scabiosa atropurpurea L., and Tithonia rotundifolia (Mill.) S.F. Blake. The results showed that the application of depolymerized gellan accelerated flowering and stimulated the growth of all assessed species, regardless of MW. The plants treated with depolymerized gellan grew higher and had greater fresh weight of their above-ground parts, higher leaf relative chlorophyll content (SPAD; soil and plant analysis development), and higher stomatal conductance (gs). The use of 56 kDa gellan fraction resulted in the formation of inflorescences with the greatest fresh weight in S. atropurpurea. Leaves of R. hirta treated with this fraction showed the highest values of SPAD and gs. This study demonstrated that gellan derivatives of low MW may be used for the production of innovative plant biostimulants.

Plant Growth Promoters

Recently, there have been many exciting new developments relating to the use of Trichoderma spp. as agents for biocontrol of pathogens and as plant growth promoters. Several mechanisms have been proposed to explain the positive effects of these microorganisms on the plant host. One factor that contributes to their beneficial biological activities is related to the wide variety of metabolites that they produce. These metabolites have been found not only to directly inhibit the growth and pathogenic activities of the parasites, but also to increase disease resistance by triggering the system of defence in the plant host. In addition, these metabolites are also capable of enhancing plant growth, which enables the plant to counteract the disease with compensatory vegetative growth by the augmented production of root and shoot systems. This review takes into account the Trichoderma secondary metabolites that affect plant metabolism and that may play an important role in the complex interactions of this biocontrol agent with the plant and pathogens.
