Effects of exogenous sucrose on leaf morphology and ploidy levels in the wild type. The wild‐type seedlings were cultured on MS plates supplemented with a series of sucrose concentrations (0.1–2.0% w/v) under low light (LL) and high light (HL) conditions. The first pairs of foliage leaves were collected at 21 days after sowing (DAS) to quantify anatomical parameters and ploidy profiles. (a) Leaf thickness, (b) the number of cell layers in palisade tissue, (c) total number of cells in palisade tissue per leaf, (d) cell height of palisade tissue, and (e) palisade cell area counted from transverse sections. Significant differences (P < 0.05) are indicated by different letters (Tukey's test). (f) Ploidy profiles. The percentages indicate the sucrose concentrations in each medium. Values represent means ± SDs (n = 6 leaves from three plants).
