Nutritional composition of plantain (<i>Plantago lanceolata</i> L.) plants cut at three frequencies (15, 25 and 35 cm extended leaf length) and at two intensities (5 and 8 cm).

abc: Different letters within a row under the frequency columns indicate differences in mean values (least significant difference (LSD), p ≤ 0.05). SEM: Standard error of the mean. Degrees of freedom of ‘Frequency’ effect: 2; Degrees of freedom of ‘Intensity’ effect: 1; Degrees of freedom of the ‘Interaction effect’ (F × I): 2; Degrees of freedom of the Residual: 18.abc：频次列下同一行中的不同字母代表均值存在显著差异（最小显著差异（least significant difference, LSD），p ≤ 0.05）。SEM：均值标准误（Standard error of the mean）。“频次”效应的自由度为2；“强度”效应的自由度为1；“交互效应（F×I）”的自由度为2；残差的自由度为18。
