“…The fact that most application modes of Trichoderma have increased the height of African mahogany seedlings for at least one of the fungus isolates, is a promising result, since if the objective is gain in height, the producers could use the best suited method to their conditions, with no losses in that variable. Amaral et al (2017) also found significant gains in seedling biomass with the inoculation of Trichoderma in substrate. The promotion of plant growth by Trichoderma isolates may be associated with the production of hormones or other factors, and with the availability of nutrients in the substrate and their facilitated absorption (Lucon, 2009).…”

“…Although Trichoderma isolates did not influence the root collar diameter of African mahogany seedlings, there are reports of the this fungus beneficial effect on this structure, as indicated by Amaral et al (2017), when evaluating isolates of T. asperellum and Trichoderma virens on J. micrantha (Caroba). They observed a significant increase in the root collar diameter of the seedling at 90 days after planting.…”

Trichoderma is a beneficial fungus that can be used in both the control of phytopathogens and in promoting germination and plant growth. Thus, this study aimed to evaluate the effect of five Trichoderma isolates (T09, T12, T52, Tc and Tce) in seven different application modes on seeds and seedlings of the Khaya ivorensis A. Chev. (African mahogany). Fungi applications were tested by microbiolization of the seeds, in the pre-planting substrate, by monthly applications in the seedlings and in four combinations of these three treatments. Under laboratory conditions, the germination, germination speed index (GSI), and radicle and hypocotyl lengths were evaluated in seeds, treated and untreated, with Trichoderma. In the nursery, it was evaluated the height, root collar diameter, number of leaflets, root length, and the dry weight of root system and aerial part in seedlings with different forms of Trichoderma application. Trichoderma isolates did not influence germination percentage, GSI and radicle length. The fungus application methods in the K. ivorensis seedlings increased the height and leaflets number of the plants by at least one of the Trichoderma isolates tested in this study.Trichoderma spp. e seus efeitos na qualidade fisiológica das sementes e no desenvolvimento de mudas de mogno africano RESUMO: Trichoderma é um fungo benéfico que pode ser utilizado tanto no controle de fitopatógenos como na promoção da germinação e do crescimento de plantas. Assim, objetivou-se avaliar o efeito de cinco isolados de Trichoderma (T09, T12, T52, Tc e Tce), em sete modos de aplicação, sobre sementes e mudas de Khaya ivorensis A. Chev. (mogno africano). Foram testadas aplicações dos fungos via microbiolização das sementes, no substrato pré-plantio, em aplicações mensais nas mudas e, em quatro combinações desses três tratamentos. Em condições de laboratório foram avaliados a germinação, índice de velocidade de germinação (IVG) e, o comprimento da radícula e hipocótilo, em sementes tratadas e não tratadas com Trichoderma. Em viveiro, avaliou-se altura, diâmetro do coleto, número de folíolos, comprimento da raiz e, a massa seca da parte aérea e sistema radicular em mudas com as diferentes formas de aplicação de Trichoderma. Os isolados de Trichoderma não influenciaram a porcentagem de germinação, o IVG e o comprimento da radícula. Os modos de aplicação dos fungos avaliados nas mudas de K. ivorensis aumentaram a altura e o número de folíolos das plantas, por pelo menos um dos isolados de Trichoderma testado neste trabalho.Palavras-chave: tratamento biológico; sementes florestais; fungos; promoção de crescimento; Khaya ivorensis Trichoderma spp. and its effects on seeds physiological quality and seedlings development of African mahogany Rev.

“…Although the biological treatments THE, TTA, TAI, THP and the chemical fungicide SCO did not show significant differences from the control, the former are still more advantageous, since these microorganisms can promote plant growth, as already evidenced in several studies (Amaral et al, 2017;Chagas et al, 2017;Gonçalves et al, 2018). Carvalho Filho et al (2008) concluded that the isolate CEN 262 of Trichoderma spp.…”

One of the main diseases occurring in clonal nurseries of Eucalyptus spp. is powdery mildew caused by the fungus Oidium eucalypti. This work evaluated the efficiency of biological products based on Trichoderma spp. and Bacillus spp. applied as preventive and curative treatments for the control of Oidium eucalypti in clonal seedlings of E. benthamii Maiden et Cambage. Treatments were: Trichoderma harzianum (THP), T. atroviride (TAI), T. harzianum (THE), Trichoderma spp. (TTA), Bacillus spp. (BNE), Sulfur (KUM), Difenoconazol (SCO) and distilled water (AD). Treatments were applied preventively by spraying seven days before inoculation of the pathogen, and in curatively, ten days after inoculation. Weekly evaluations of the incidence and severity of the disease were done. The analyzed variables were: Disease Index (ID) and Incidence (I), calculating the area under the disease curve (AUDPC) for each treatment. The results pointed BNE (Bacillus spp.) and TAI (isolate T. atroviride) as effective preventive treatments and BNE (Bacillus spp.), applied curatively for the control of O. eucalypti in E. benthamii seedlings, proving that treatments based on biological products may be effective for controlling eucalyptus powdery mildew in clonal nurseries.

“…in producing native forest species and its effects on the growth process are concentrated in a limited number of species, such as Theobroma cacao (Bae et al, 2009;Tchameni et al, 2011), Gochnatia polymorpha (Machado, Tavares, Lopes, & Silva, 2015), Prunus sp. (Sofo, Milella & Tataranni, 2010), Myrcianthes punges, Eugenia pyriformis (Soldan, 2014) and Jacaranda micrantha (Amaral, Steffen, Maldaner, Missio, & Saldanha, 2017). Given this gap, the objective of this study was to evaluate the effect of Trichoderma on the germination and initial growth of M. ilicifolia seedlings, aiming to develop production technologies compatible with the final use of the raw material.…”

The interest in using biotechnology tools that contribute to reducing the need for chemical inputs in agroforestry production has increased in recent years, aiming at higher quality for the environment and for society. This interest is also applied to medicine species consumed in natura. The objective of this study was to evaluate the effect of Trichoderma spp. on germination and initial growth of Maytenus ilicifolia seedlings. Laboratory and greenhouse tests were carried out using Trichoderma spp. isolates obtained from three different strains identified as Trichoderma asperelloides (T1 & T2 strains) and Trichoderma virens (T10 strain). In laboratory, M. ilicifolia seeds without aryl were inoculated in solutions containing fungal spores and distributed in substrate paper in four replicates of 25 seeds/treatment. The first germination count, accumulated germination, percentages of accumulated dead seeds and firm seeds were evaluated at 7, 14, 21 and 28 days of incubation. The same isolates were used to evaluate the effect on the initial growth of seedling in a greenhouse through a completely randomized design with 40 replicates, considering a seedling as each replicate. Trichoderma spp. isolates were inoculated on the substrate used as the basis for seeding. Seeds of M. ilicifolia were used from the same batch of the laboratory test, but without removing the aryl. The variables of total height, diameter at root collar and number of leaves were evaluated at 90, 120, 150 and 180 days after seeding. A positive effect of Trichoderma inoculation on seed germination and vigor was observed in the laboratory, with emphasis on the T2 isolate. Growth promoting effects on the M. ilicifolia seedlings were not observed in greenhouse. We suggest to better investigate the interaction between the tested Trichoderma isolates and M. ilicifolia seeds in the presence of aryl.
