Raman spectra analysis of leafy vegetables at high density planting. a Phenotype of Kai Lan and Choy Sum in low to high density conditions (plants/pot). Scale, 5 cm. b Ratio of petiole length to leaf blade area of leafy vegetables in a (n = 3). c Carotenoid Raman peaks of Kai Lan and Choy Sum (leaf blade: n = 6, petiole: n = 4). Bars denote average ± SE. Statistical significance between control (1 plant/pot) and high density planting was determined by two-tailed Student’s t-test: *P < 0.05; **P < 0.01
