Development of Forestry Species Inoculated with Trichoderma spp. Fertilized with Rock Phosphate

Abstract

The study aimed to determine the effects of inoculation of Trichoderma spp. on the development and extraction of nutrients from Eugenia pyriformis Cambess. (uvaieira) and Myrcianthes punges (O.Berg.) (guabiju) subjected to fertilization with rock phosphate. The treatments used at planting were: Control; Trichonat PM  ; Trichoderma sp. FS1; Rock phosphate; Trichonat PM  + Rock phosphate; and Trichoderma sp. FS1 + Rock Phosphate. The following characteristics were evaluated at 540 days after planting: plant height, crown diameter, branch insertion points, biomass, and nutrient content. The uvaieiras inoculated with Trichonat PM  and Thrichoderma spp. showed higher vegetative growth and higher values of N, P, K, Ca, Mg and S, respectively. For guabijuzeiros, the treatment with Trichoderma spp. presented the highest insertion point of the branches without phosphorus fertilization However, the treatments did not affect nutrient extraction. Thus, Trichoderma spp. inoculants have the potential to promote vegetative growth and nutrient extraction in plants.

Trichoderma Contributes to the Germination and Seedling Development of Açaí Palm

“…In the literature, there are numerous other studies evaluating fungi of the genus Trichoderma as a biocontrol agent of diseases, as promoter of growth of agricultural, or forest species, presenting promising results [25,[50][51][52][53][54][55][56][57][58]. The results for E. oleracea found in this work show that Trichoderma can contribute to the growth of plants of this palm tree, allowing that sustainable practices can be adopted in the preparation of seedlings of this species.…”

Trichoderma spp. on treatment of Handroanthus serratifolius seeds: effect on seedling germination and development

“…Carvalho Filho et al [56] tested the effects of T. asperellum CEN 162 and T. harzianum CEN 262 on seedling growth for a hybrid eucalyptus clone, and they recorded an improved average plant aerial portion and root dry weight in seedlings treated with these fungi. Soldan et al [55] also reported increases in biomass when they tested an isolate of Trichoderma spp. and Trichonat PM in the development of Eugenia pyriformis and Myrcianthes pungens seedlings.…”

“…That said, many isolates are thought to increase nutrient absorption and thus biomass production, resulting in better seedling growth outcomes [32]. Although the effect of indole-3-acetic acid, a metabolite commonly produced by Trichoderma isolates, is not evaluated in this study, some authors attribute observed growth benefits in seedlings treated with Trichoderma species to improved nutrient solubility imparted by this compound [55,56,58].…”

“…isolate FS1 and Trichonat PM (a Trichoderma based product) on the development of Eugenia pyriformis (uvaieira) and Myrcianthes pungens (guabijuzeiro) seedlings, both of which are native species to southern Brazil. The authors reported positive effects on plant growth (height) for Eugenia pyriformis, with Trichonat PM treatment resulting in greater plant height when compared to the control group [55]. Machado et al [22] also observed increases in plant height when using T. harzianum isolates to promote the growth of Gochnatia polymorpha (cambar a) seedlings, a native tree species from southern Brazil.…”
