Effects of Blue and Red Light Treatments on the Growth and Leaves Development of Apple seedlings. a Growth status of apple seedlings after 30 days of different light quality treatments. Scale bars = 10 cm b Plant height, c stem thickness and e leaf area after of apple seedlings after 30 days of different light quality treatments. Values are means ± SD of three independent biological replicates. The uppercase letter indicates a very significant difference at the 1 % level (P < 0.01), and the lowercase letter indicates a significant difference at the 5 % level (P < 0.05). d Comparison of apple leaf morphology after 30 days of different light quality treatments. The leaves were taken from the third to fifth functional leaves, as shown by the arrows in Fig. 2a. Scale bars = 2 cm. f Leaf anatomy of apple leaves treated with different light quality. E: epidermis; PT: palisade tissue; VB: vascular bundle; W: white light; B: blue light; R: red light. Scale bars = 100 μm. g Chloroplast ultrastructure of apple leaves under different light conditions. The bars shown are 10 μm, 2.5 μm, 1 μm, and 0.5 μm from left to right respectively. M: Mitochondria; S: Starch grain; O: osmiophilic granules; SL: stroma lamella
