“…Guaco plants grown in light environments show results contrary to this research, as those grown under aluminet and red meshes had higher values of chlorophyll a, b, and total (BRITO et al, 2020). However, plants grown in full sun generally have higher chlorophyll contents because the amount of solar radiation influences plants' metabolism and the quality of light that reaches the photochemical reaction center to excite chlorophyll.…”

“…The positive performance of the root dry mass of plants grown under mesh suggests that light environments contribute to the displacement of photoassimilates inside the plants, stimulating cell division, favoring the growth of the root system and, consequently, the absorption of water and nutrients. by the roots (BRANT et al, 2009;SOUZA et al, 2010;OLIVEIRA et al, 2017;LIMA et al, 2018;BRITO et al, 2020). However, Martins et al (2008), studying Ocimum gratissimum L., found a contrasting result to this research, in which plants grown under full sun showed greater allocation of dry mass to the root.…”

“…The quality of light potentiates the photosynthetic process. For example, modifications of the incident radiation stimulate the increase in total dry mass of guaco (Mikania glomerata), showing the phenotypic plasticity of this species (BRITO et al, 2020).…”

“…On the other hand, these indices did not differ between the two types of shading. Direct solar radiation in plants ensures greater efficiency in the absorption and transfer of energy for the photosynthetic process (BRITO et al, 2020).…”

Growth of Basella alba under different light environments

et al. 2022

Basella alba L. (Malabar spinach) is a non-conventional food plant (PANC) with high nutritional value and economic potential. Light is a critical factor in plant growth, acting directly on the photosynthetic process. The photoselective meshes combine the physical protection of plants with the selective filtering of solar radiation to promote physiological responses. This work evaluates the growth of B. alba under different light environments. The experiment occurred in a greenhouse at the Center for Agrarian, Environmental and Biological Sciences of the Federal University of Recôncavo da Bahia in a completely randomized design with plots comprising one useful plant and five replications. The plants were grown in three light environments: red ChromatiNet mesh, aluminet-thermo reflective mesh (both with 50% irradiance), and under full sun. The red mesh increased the root dry matter mass and stem diameter. The aluminet mesh increased the average number of leaves by about 50% compared to the plants cultivated under full sun. The results show that the cultivation of B. alba in different light environments promotes morphophysiological changes with positive increments in growth.
