“…Stimulate ® has been used in several crops with satisfactory results regarding shoot growth, as observed for Hymenaea courbaril L. (SMIDERLI et al, 2022). Hormonal treatment in seeds positively contributed to germination and seedling formation of Myrtaceae species (HOSSEINI et al, 2020;PIROLA et al, 2021), which is similar to what was observed for M. glomerata.…”

“…Physiologically, the balance of these hormones act on starch hydrolysis (BEWLEY et al, 2013), which favors the availability of reserves for formation of roots and hypocotyl (SKUBACZ; DASZKOWSKA, 2017;TAIZ et al, 2017). This was likely responsible for the higher values of shoot length and shoot and root dry weights, as Stimulate ® increases plant growth and development by stimulating cell division, differentiation, and elongation (SANTOS et al, 2013;SMIDERLI et al, 2022), making it a tool for the improvement of seed and plant physiology. This product can usually be used in the treatment of seeds, but there are also studies on the management of application using other products.…”

Myrciaria glomerata O. Berg. (Myrtaceae) is a fruit tree native to the Brazilian Atlantic Forest with potential for use as food and medicine, besides having good ecological potential. However, this species is limited by low germination rates. Thus, this study aimed to evaluate different methods to overcome dormancy in seeds of M. glomerata and to improve seedling vigor. For this, two experiments were conducted. In Experiment 1, seven treatments were tested: a control treatment, immersion in water at 100 ºC for 30 seconds, immersion in concentrated sulfuric acid (H2SO4) for 1 and 5 minutes, immersion in an aqueous solution of gibberellic acid (GA3) at the concentrations of 250 and 500 mg L-1 for 24 h, and seeds homogenized with an aqueous solution of Stimulate® at a concentration of 5 mL kg-1 seed. In Experiment 2, six doses of Stimulate® were tested: 0, 5, 10, 15, 20, 25, and 30 mL kg-1 seed. The immersion of seeds in 250 and 500 mg L-1 GA3 contributes to increase germination rates, seed length, fresh mass, and dry mass compared to the control and the other methods tested. Immersions in water at 100 ºC and in H2SO4 are not recommended for M. glomerata. The treatment with Stimulate® at 15–25 mL kg-1 seed increased all characteristics analyzed. Immersion in 250 mg L-1 GA3 and Stimu-late® at 20–25 mL kg-1 seed efficiently stimulated seeds to overcome dormancy in M. glomerata, as well as improved seedling vigor.

Objective: This study aimed to describe a methodology that involves obtaining a temporal scale in days, along with the technical information necessary to obtain maximum vigor of Pochota fendleri seedlings when sown in containers and/or Gerbox boxes, as well as their quality. Method: The experimental design was completely randomized, with four replicates, composed of 25 seeds of medium size and light brown color. Result and conclusion: Emergence of Pochota fendleri seedlings grown from freshly harvested seeds of medium size and light brown color sown was 97% at 10 DAS, with emergence speed index of 13.2. Freshly harvested seeds of medium size and light brown color sown are recommended for the production of Pochota fendleri seedlings. Research implications: Obtaining knowledge that guides appropriate practices and the temporal scale is essential for the production of seedlings of native forest species. These seedlings can enhance the success of planting forest stands for timber or non-timber purposes, besides ensuring the establishment and survival to programs for restoration of degraded areas.
