“…& Hook.f. ex S.Moore (Souza and Freire, 2018) and Cojoba arborea (L.) Britton & Rose (Carvalho et al, 2021) etiolate under higher shading levels due to their hormonal relationships (Pinho et al, 2022). This fact is also associated with the ecological group of each species, which becomes a negative factor, especially for seedlings in the initial phase.…”

Depending on the intensity and ecological successional classification of plants, light availability can become an unfavorable condition for producing high-quality seedlings. We hypothesized that applying silicon sources might contribute to inducing tolerance to different shading levels for Peltophorum dubium (Spreng.) Taub. seedlings. Two independent experiments were developed: I) the application of five doses of silicon oxide (SiO2: 0.0; 1.0; 2.0; 4.0; and 6.0 g L-1); and II) the application of five doses of potassium silicate (K2SiO3: 0.0; 5.0; 10.0; 15.0; and 20.0 mL L-1 of water). Both were associated with three shading levels: 0% (direct sunlight), 30%, and 50%. In experiment I, we observed that seedlings were more responsive to shading levels and had little influence from foliar application of SiO2, with higher growth, biomass, and quality values when grown under direct sunlight (0% shading). In experiment II, the foliar application of 20.0 mL L-1 of K2SiO3 contributed to greater heights under 0% and 30% shading. Meanwhile, under 50% shading, the dose of 5.0 K2SiO3 favored the species' growth. The application of K2SiO3 favored the increase in the dry mass of the aerial part (DMAP). The highest biomass production and seedling quality occurred under 0% and 30% shading. The 50% shaded environment was most unfavorable to the growth and quality of P. dubium seedlings. Even though the seedlings were not very responsive to silicon sources, K2SiO3 provided a greater response than SiO2. High-quality seedling production is favored when the seedlings are grown under direct sunlight (0% shading).

“…The use of the commercial substrate is quite common, based on the assumption of easy availability and its reputation for being suitable for seedling development. Carvalho et al [29], when evaluating the production of Cojoba arborea seedlings in different substrates, also observed positive results for fresh ground and root mass when using the commercial substrate.…”

Seed germination is considered the crucial phase in the establishment and development of plants. Knowledge about the appropriate conditions for seed germination is of fundamental importance, mainly due to the influence and different responses that they can present depending on several factors such as seed viability, light, water, oxygen, temperature, and substrate, among others. Therefore, the main objective of the work was to evaluate the germination and the initial development of the A. macrocarpa in the function of different substrates. The experimental design adopted was completely randomized, where six different substrates were used in four replications. The treatments consisted of S1 (Commercial Substrate); S2 (Washed Sand); S3 (Commercial Substrate 50% + Vermiculite 50%); S4 (Commercial substrate 50% + Rice straw 25% + Pine bark powder 25%); S5 (Black Soil); S6 (Black Soil 75% + Sawdust 25%). The evaluated characteristics were germination percentage (%), emergence speed index, shoot and root length (cm), shoot and root fresh mass (gram), and shoot and root dry mass (gram). The use of commercial substrate + vermiculite stood out for most of the analyzed characteristics, being germination (78.57%), aerial part fresh mass (0.1187g), root fresh mass (0.0263g), aerial part dry mass (0.0689g) and root dry mass (0.0149g). The lowest averages observed for all characteristics were with the use of black soil substrate.
