Fig 3. Comparisons of vein length per unit area (VLA) (a), area (b) and perimeter (c) of jujube leaves of 21 representative jujube varieties sampled in 33 sites in northern China.

Fig 3

The jujube varieties are represented by different capital letters for the sake of clarity. The error bars are standard deviations of the variables concerned. The least significant difference (LSD) multiple comparison tests were conducted for VLA (df = 62, F = 21.10, p<0.05), leaf area (df = 62, F = 112.472, p<0.05), and leaf perimeter (df = 62, F = 8.016, p<0.05), respectively. Different lowercase letters above error bars for each component indicate statistically significantly different mean values (p<0.05).
