“…The incidence of photosynthetically active radiation is the micrometeorological factor that most influences plant growth inside protected environments [16], and the reflectance of the light generated by the growing benches with white reflective material inside the protected environment favored the growth, and photosynthetic activity of baby leaf kale, although the characteristics evaluated showed some different responses depending on the color of the bench.…”

“…The wavelengths provided in the reflection were efficient in activating the photosynthetic pigments components of photosystems I and II (chlorophylls and carotenoids), providing sufficient light energy for photophosphorylation and production of ATP and NADPH2 necessary for the next stage of photosynthesis, with a production of photoassimilates for accumulation of leaf dry mass and bioactive compounds. Furthermore, the reflection of the colored sheets provides greater availability of light energy and an increase in the number of leaves of baby leaf kale, improving their use for photosynthesis [16].…”

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.

Background Oiti (Licania tomentosa[Benth.] Fritsch) is an option for urban forestation and rural environments that require shading by plants, so studying the plant environment to obtain quality seedlings is essential. The present study aimed to evaluate oiti seedlings in different protected environments with or without reflective material on a cultivation bench. Methods The following protected environments were evaluated: an agricultural greenhouse covered with a low-density polyethylene film and a thermo-reflective screen with 42%/50% shading under the film; an agricultural screenhouse with an aluminized screen with 35% shading; an agricultural screenhouse with a black screen with 30% shading; and an agricultural screenhouse with a black screen with 18% shading. Production systems with and without photosynthetically active radiation-reflecting material (aluminized screen, Aluminet®) on the cultivation bench were assessed in each protected environment. Results There was no interaction between the environmental factors; however, the environments influenced height, stem diameter, root dry matter, and total biometric relationships and growth rates. The reflective material did not improve the quality of oiti seedlings. The ratio of shoot and root dry matter was, on average, 71% for the shoots and 29% for the roots. The photosynthetically active radiation received by oiti seedlings ranged from 600 to 1,100 μmol m−2s−1. Conclusions The greenhouse with 42%/50% shading screen under the film and the black screen with 30% shading were the best environments for the formation ofLicania tomentosaseedlings. The reflective material on the cultivation bench did not result in better quality oiti seedlings.
