Powly Mathew, Sranya J, Anitta M George, Abin Sebastian
The growth and phytochemical constituents of Amaranthus cruentus L. and Amaranthus palmeri S. Wats. under light and shade conditions were studied. It found that growth of plants in light result more height, number of leaves, and biomass. It also noticed that the plants grow in shade accumulate less soluble protein, sugar, phenolics, anthocyanin and malonyldialdehyde. However, more accumulation of photosynthetic pigments was found in plants grow in shade. The results shows that Amaranthus varieties grow in open field will have better vegetative growth, biomass productivity and phytochemical constituents. Therefore, an optimized light management practice should be adopted to ensure the successful cultivation of Amaranthus cultivars in vertical farming.
