“…Other species have shown different DM distributions than those observed in the present study, for example, for papaya seedlings (Carica papaya), an average of 67% for the shoot and 33% for the root system were observed (Cabral et al, 2020) and for achachairu (Garcinia humilis) seedlings, 68% were found for shoot and 32% for root system (Silva et al, 2021); both surveys in 1.8 L polyethylene bags, different from the present study tubes that can restrict root growth and influence this distribution.…”

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 positive influence of the reflective material on the number of fruits is in line with the results found by Santos et al (2017) for passion fruit seedlings (Passiflora edulis Sims f. flavicarpa Deg. ), Salles et al (2017) for Java plum seedlings (Syzygium cumini), Mortate et al (2019) for paricá seedlings (Schizolobium amazonicum), Costa et al (2020b,c) for baru seedlings (Dipteryx alata), and Cabral et al (2020) for papaya seedlings (Carica papaya). According to Salles et al (2017), this material reflects part of the photosynthetically active radiation that reaches the benches to the leaves, which provides higher availability of light energy (Figure 2), improving its use to perform photosynthesis.…”

Plant ambiance studies the environmental condition favorable to plant growth at the initial stage of seedlings or the complete production cycle. This study aimed to evaluate the cultivation of the ornamental pepper 'Pyramid' under protected environments and growing benches with and without reflective material. The protected environments consisted of a greenhouse covered with low-density polyethylene film and 42/50% shading thermo-reflective screen under the film, structure with 35% shading thermoreflective aluminized screen, and structure with 30% shading black screen. The growing benches were tested in environments without and with reflective material made of aluminized screen. The environment of the agricultural greenhouse covered with lowdensity polyethylene film and 42/50% thermo-reflective screen under the film favored the growth of ornamental pepper plants regarding height and diameter and provided early flowering and high fruit production. The use of the reflective material showed no significant results for plant height, stem diameter, and the number of leaves. The use of reflective material increased the number of fruits in plants under the environments with 35% shading aluminized screen and 30% shading black screen.

“…The responses of different species to reflective benches may vary. Thus, it is noteworthy that the literature comments that the use of reflective material on the growing benches increases the photosynthetically active radiation, making it possible to increase photosynthesis in papaya seedlings [17], however, for baby leaf kale these results were only significant on the white bench favoring the development and quality of baby leaf kale.…”

Background: Several environmental factors can strongly influence the accumulation of glucosinolates and plant pigments. This study aimed to evaluate the growth and bioactive compounds production of baby leaf kale on colored reflective growing benches with different wavelengths; Methods: In an greenhouse, five types of growing benches were assessed without and with bright reflective colored materials: control and reflective bright (white, yellow, red, and blue); Results: The growing bench with laminated white reflective material increased the photosynthetically active radiation the most. The use of growing benches with laminated reflective material increased the production of baby leaf kale, in which the white, yellow, red, and blue laminates increased the number of leaves by 35.5, 26, 25, and 20.8%, respectively, and the shoot fresh mass by 132, 112, 112, and 109%, respectively. Using the growing bench reflective bright blue laminate increased the bioactive compounds of baby leaf kale plants, increasing chlorophylls A, B, and total by 72, 67, and 70% respectively, and carotenoids by 55%; Conclusions: The use of reflective materials is an alternative method that provides plants with better conditions for assimilating photosynthetically active radiation, increasing the development, yield, and production of bioactive compounds that promote human health.
