“…The stimulatory and positive effects of scarification on germination as well as growth traits had been reported for some tree species of the Fabaceae as Tamarindus indica (Muhammad and Amusa, 2003), Prosopis juliflora (Zare et al 2011), Centrosema pubescens (Rusdy, 2015) and Gleditsia caspica (Nourmohammadi et al, 2019). The pre-germination methods of mechanical scarification positively influenced the growth and quality of T. indica seedlings (Gomes and de Sá, 2019).…”

The present study was conducted during two successive seasons of 2020 and 2021 to determine the effect of some pregermination treatments on germination and seedling growth of Tamarindus indica and Melia azedarach. In this study, seeds of the two species were subjected to seven treatments i.e. soaking seeds in GA3 at 1000, 2000 and 3000 ppm for 24 h.; immersing seeds in concentrated sulphuric acid for 10 and 20 min.; seed scarification by steel file and untreated (control) seeds. Seeds were sown in poly ethylene pots (25 x 30 cm) under normal environmental condition for germination. The highest germination percentage was recorded in seeds of the two species treated by mechanical scarification, followed by immersion in concentrated sulphuric acid (98%) for 20 and 10 minutes. Meanwhile, the lowest values of germination percentage were obtained with the control, followed by soaking seeds in GA3 at 1000 ppm compared to other treatments. Mechanical scarification, followed by concentrated H 2 SO 4 for 20 and 10 min. led to highly significant reduction in time to attain 50% germination as well as the highest values of vigor index for the tested species in the 1st and 2nd seasons compared to other treatments. Also, the results showed that the pregermination treatments have a significant effect on the growth performance (shoot and root length, number of leaves, fresh and dry weight of shoots and roots as well as chlorophyll content) of M. azedarach and T. indica. The highest values of the growth parameters were obtained from applying scarification and concentrated sulphuric acid for 20 and 10 min., respectively. The study recommended mechanical scarification and sulphuric acid for 20 minutes for the best seed germination and seedling growth of these tree species.

“…In the biological control of phytopathogens, Trichoderma spp. stands out due to its bioprotective action against the attack of pathogens during germination, promoting initial seedling growth, as well as the solubilization of insoluble micronutrients in the soil, increasing the vigor and yield of plants (Missio et al, 2016;Gomes et al, 2019).…”

Microbiolization of cowpea seeds with commercial strains of Trichoderma asperellum and T. harzianum

Microbiolization of cowpea seeds with commercial strains ofTrichoderma asperellum and T. harzianum 1 Seed microbiolization has been increasingly contributed to researches due to its beneficial action in the initial growth of seedlings and control of phytopathogens. Thus, the aim of this study was to evaluate the initial growth and control of fungi associated with cowpea seeds by the seed microbiolization with commercial strains of Trichoderma spp. Seeds of cowpea cultivar 'BRS Gurguéia' were analyzed in a completely randomized design, with four replications, using five commercial strains based on Trichoderma asperellum and T. harzianum (Trichodermax®, Quality®, Trichodermil®, Agroguard® and Ecotrich®) and two control treatments, represented by untreated seeds (negative control) and the fungicide carbendazim (positive control). Sanity, germination, emergence and electrical conductivity tests of seeds were carried out to confirm the hypotheses. Seed microbiolization with Trichoderma asperellum and Trichoderma harzianum are effective in reducing the incidence of fungi and have antimicrobial activity similar to synthetic fungicide. The strains T. asperellum T-211 (Trichodemax®), T. asperellum URM-5911 (Quality®) e T. harzianum ESALQ-1306 (Trichodermil®) promote increases for seed vigor. The percentage of seed emergence is maximized with the application of strains T. asperellum (Quality® and Trichodemax®). The commercial strains of Trichoderma tested increase the initial growth of cowpea seedlings cv. 'BRS Gurguéia'.
