Fig. 6

Chloroplast ultrastructure of Welsh onions under different light conditions. Transmission electron microscopy observations of mesophyll cells in Welsh onion leaves exposed to W Light (w1-w3) and B, G, Y, R Light (b1-r3). The bars shown are 10 μm, 2 μm, 1 μm, respectively. The size and arrangement density of chloroplasts could be clearly seen at 10 μm and 2 μm, and the grana lamella and stroma lamella of chloroplasts could be clearly seen at 1 μm. Ch: chloroplast; GL: grana lamella; SL: stroma lamella; white arrow: osmiophilic particles; W: white light; B: blue light; G: green light; Y: yellow light; R: red light
