“…Dry matter is a critical quality parameter that indicates the degree of development of a plant, as it indicates the increase in matter accumulation over time in the nursery without considering the water present in the plant. The shoot, root, and total DM of the plants, in the different ways and concentrations applied in the present study, agree with the results of Fe doses applied via nutrient solution (Moschini et al, 2019). Low Fe concentrations decrease shoot (Da Silva et al, 2011;Khan et al, 2020) and roots DM (Li et al, 2019), factors that were not verified in the present study with the forms and doses applied.…”

Iron (Fe) is shown to be of great importance in some specific functions, and without it, the plant can experience a nutritional imbalance, thus affecting its development. The present study aimed to evaluate the effects of the application of Fe doses in coffee (Coffea arabica L.) 'Obatã IAC 1669-20' seedlings via foliar, previous fertilization of the substrate, and aqueous solution on the substrate and identify the best management. The experiment was carried out in a completely randomized design, with seven treatments and five replicates. The treatments were five Fe concentrations via foliar (0.30, 0.45, 0.60, 0.75, and 0.90 g of Fe L -1 ), previous fertilization on the substrate (0.372 g Fe m -3 ), and aqueous solution on the substrate (0.30 g Fe L -1 ), totaling seven treatments. Fertilization with Fe via foliar at 0.45 g Fe L -1 in the production of coffee seedlings showed significant influence on seedling height, stem diameter, and leaf area, in addition to having one of the highest values of Dickson quality index. Thus, coffee seedlings with the application of 0.45 g Fe L -1 via foliar had the best results, with 11.2 cm height, 4.1 mm diameter, 17.3 cm 2 leaf area, and 0.32 Dickson quality index. It promoted seedlings with more significant gains in the foliar area (24.2%) and stem diameter (27.4%), allowing a shorter time in nursery. The treatment aqueous solution 0.30 g Fe L -1 on the substrate is a second option for the Fe application in coffee 'Obatã IAC 1669-20' seedlings. The treatment with the previous fertilization of the substrate with 0.372 g Fe m -3 is the less recommended.

“…The presence of the boron, which is in bigger quantity in the MS medium, promote synthesis of indolacetic acid (AIA) and acts translocation of natural auxin, promoting the rooting. The bigger dry biomass values were found in the MS medium that is more concentrated in salts and nutrients, being an important attribute of growth (Moschini et al, 2019).…”

The objective of this work was to evaluate asepsis protocols, composition and concentration of culture media in the in vitro establishment of three physalis species. In experiment I, seeds of 3 species were used x 3 asepsis protocols. In experiment II, 3 culture media and explants 3 species were used. In experiment III, explants of 2 species x 4 concentrations of MS culture medium were used. In experiment IV, explants of 2 species x 4 sucrose concentrations were used. For experiments II, III and IV after 30 days were evaluated some phytotechnical parameters. The experimental design was completely randomized, in a 3 x 3 (experiments I and II) and 2 x 4 (experiments III and IV) factorial scheme. Protocols II and III were appropriate for P. peruviana germination, and I and III for P. minima, the three protocols were efficient for controlling fungi and bacteria. The MS is the most suitable for the in vitro establishment of three species. The culture medium at 100% concentration obtained better values in the in vitro development parameters evaluated for the species P. peruviana and P. minima. Sucrose concentrations close to 50 and 20 g L -1 favored the establishment of P. peruviana and P. minima.
