Table 2.

Correlations among C:N, C:P, and N:P in leaves of differently aged lucerne stands.

	Cut	C:P			N:P
		4	5	Average (age)	4	5	8	11	Average (age)
C:N	First			0.881∗∗					0.714∗∗
	Second								–0.660∗
	Third			0.741∗∗
	Average (cut)	0.983∗∗	0.892∗∗	0.799∗∗	0.941∗∗				0.476∗∗
C:P	First			1					0.958∗∗
	Third			1					0.940∗∗
	Average (cut)	1	1	1	0.986∗∗	0.924∗∗	0.928∗∗	0.844∗∗	0.907∗∗

The data of all cuts are used for analyzing the correlations in a row and the data of all ages are used for analyzing the correlations in a column. Only the cases with significance are shown in the table. 4, 5, 8, and 11 refer to stand age in year and first, second, and third refer to the cut of one age. The asterisk (^∗) shows significant correlations at P < 0.05 and double asterisks (^∗∗) show significant correlations at P < 0.01.
