Effects of Growing Cycle and Genotype on the Morphometric Properties and Glucosinolates Amount and Profile of Sprouts, Microgreens and Baby Leaves of Broccoli (Brassica oleracea L. var. italica Plenck) and Kale (B. oleracea L. var. acephala DC.)

Some new foods (sprouts, microgreens and baby leaf) of the brassica genus are appreciated for their nutritional nutraceutical values. The aim this experimental trial was to improve traits these by evaluating effects climatic condition, genotype, plant growth stage on development greater quality in relation foods. morphometric glucosinolates (GLSs) three traditional Italian cultivars Brassica oleracea crops, such as broccoli (B. var. italica), namely Sicilian landrace ‘Broccolo Nero’ (BN) commercial ‘Cavolo Broccolo Ramoso Calabrese’ (CR), well kale cultivar Laciniato Nero di Toscana’ (CL) acephala DC.), were evaluated an unheated greenhouse Catania during end 2019 beginning 2020. Plant studied at different phenological stages—from seeds sprouts, microgreens, leaves—over two growing cycles, one autumn–winter other spring–summer. showed more rapid biomass production than (i.e., weight, hypocotyl length, leaf width). GLS profile varied significantly (p < 0.05), both plant’s genotype. highest amount glucoraphanin detected BN leaves, about 8 µmol g−1 d.w., whereas glucobrassicin its related derivatives 14 d.w. leaves CL 15 10 CR, respectively. These can also be produced home with simple cheap equipment
