^†DMC, dry matter content; SLA, specific leaf area; LT, leaf thickness; SL, stomatal pore length; SD, stomatal density; SPI, stomatal pore index; CTR, cell tense ratio; SR, spongy tissue ratio; AB, abaxial cell thickness.
^‡The numbers of samples are shown in the upper right section of the matrix. The correlation coefficients (r) are shown in the lower left section of the matrix. *P < 0.05; **P < 0.01.
