Growth conditions trigger genotype-specific metabolic responses that affect the nutritional quality of kale cultivars.

ABSTRACT: Kales (Brassica oleracea convar. acephala) are fast-growing, nutritious leafy vegetables ideal for year-round indoor farming. However, selection of the best cultivars for growth under artificial lighting necessitates a deeper understanding of leaf metabolism in different kale types. Here we examined a curly-leaved cultivar, Half Tall, and a lacinato-type cultivar, Black Magic, under moderate light (130 µmol photons m-2 s-1/22 °C) and high light (800 µmol photons m-2 s-1/26 °C) conditions. These conditions induced genotype-dependent differences in nutritionally important metabolites, especially anthocyanins and glucosinolates (GSLs), in kale cultivars. In the pale green Half Tall, growth under high light conditions did not induce changes in either pigmentation or total GSL content. In contr
