Bottom Line: Griff), is ideal material for identifying leaf features associated with K leaf and gas exchange.We conclude that leaf morpho-anatomical traits and N content per leaf area strongly influence K leaf.Our results suggest that more detailed anatomical and structural studies are needed to elucidate the impacts of leaf feature traits on K leaf and gas exchange in grasses.

Correlation of leaf N content per leaf area and Kleaf. Values shown are mean ± SD, and data were fitted by power adjustment. Regression coefficients and significance are shown when P was <0.05 (**, P < 0.01).

Figure 4: Correlation of leaf N content per leaf area and Kleaf. Values shown are mean ± SD, and data were fitted by power adjustment. Regression coefficients and significance are shown when P was <0.05 (**, P < 0.01).

Mentions: Across all cultivars, Kleaf was positively correlated with leaf area (r = 0.80, P < 0.01), leaf length (r = 0.62, P < 0.05), and leaf width (r = 0.66, P < 0.05) (Fig. 1). No significant correlation was observed between Kleaf and VLA, VLAmajor, or VLAminor. However, a positive correlation (r = 0.86, P < 0.01) between the proportion of minor vein length and Kleaf was observed (Fig. 2). In addition, Kleaf was positively correlated with LMA (r = 0.83, P < 0.01), IVD (r = 0.92, P < 0.01), Tleaf (r = 0.67, P < 0.05) (Fig. 3), and leaf N content per leaf area (r = 0.86, P < 0.01) (Fig. 4). IVD and Tleaf were positively correlated with leaf N content per leaf area, while VLA was independent of leaf N content per leaf area (Fig. 5). In order to identify the direct effects of leaf N content per leaf area on Kleaf, a multiple regression analysis was performed between Kleaf and leaf N content per leaf area, Tleaf, and IVD. Our results show that Kleaf tightly correlated with N content per leaf area (P = 0.015) compared with Tleaf (P = 0.673) and IVD (P = 0.052).
