图2 不同养分处理下臭椿、翠菊和加拿大一枝黄花第4天、8天、12天的侧根数、一级侧根长和总根长比较(用Duncan多重比较法)。不同小写字母表示同一观察时间不同养分处理之间差异显著(p < 0.05); 不同大写字母表示同一养分水平下不同观察日期之间差异显著(p < 0.05)。

Fig. 2 Comparisons of number of laterals, length of 1st order roots and total root length of Ailanthus altissima, Callistephus chinensis, Solidago canadensis on day 4, 8 and 12 under different nutrient treatments with Duncan’s multiple comparison. Different small letters indicate significant differences among nutrient levels on each sampling date (p < 0.05). Different capital letters indicate significant difference among sampling dates at the same nutrient level (p < 0.05).
