Table 2. N and K on growth, N content, and root architecture of moso bamboo seedlings.
Analytical results are means ± SE (n = 36). Mean values followed by the same letter (a, b, c, d, e, or f) are not significantly different within the same column according to a Duncan’s multiple comparison test at P < 0.05.
