muscari As shown in Figure 3 , there was a highly significant ( p < 0.001) quadratic relationship between nitrogen application rate and photosynthetic performance of L. muscari leaves.
muscari As shown in Figure 3 , there was a highly significant ( p < 0.001) quadratic relationship between nitrogen application rate and photosynthetic performance of L. muscari leaves.
The Chl (a/b) ratio showed a decreasing trend in the N0–N3 nitrogen application range and rebounded to 3.388 ( p < 0.05) in the high nitrogen level range of N3–N5.
muscari leaves showed a trend of first increasing and then decreasing, reaching their maximum values in N3, which were 77.04%, 42.59%, and 24.94% higher than in N0, respectively.
muscari rose significantly ( p < 0.05), while the crown width, number of leaves, and number of tillers exhibited an overall trend of first increasing and then decreasing.
