Emission of monoterpenes of four individual plants of P. Meidarland Bellina Age ‘LM128’. The plants were treated with 100 μmol m⁻² s⁻¹ white light (WL), and 270 μmol m⁻² s⁻¹ blue light (BL) conditions. The replicate number for each plants was listed as following: a No. 1 plant: n = 3 for white light (WL), and n = 4 for blue light (BL). b No. 2 plant: n = 1 for WL, and n = 4 for BL. c No. 3 plant: n = 3 for both WL and BL. d No. 4 plant: n = 3 for WL, and n = 1 for BL. Different letters on the column indicate significant difference by Student’s t test (p value < 0.1). Scale bar = 1 cm
