Plasticity index
F, N, C and their interaction (W × N × C) had significant effect on the plasticity index of both the species (Table 3). Dry weight, LN were non-significant under W × C, C and W × N. While F, N, C and their interactions i.e. W × N, W × C, C × N and W × N × C had significant effect on the plasticity index of plant height, DW, SLA, chlorophyll content and leaf nitrogen (Table 3). Out of the five traits, SLA was the most plastic (F = 118.712, P<0.01) with a range of 0.13 to 0.325 (Fig. 3g). The plasticity index was higher in all traits of WT as compared to WC, except LN and CHl (P<0.05, Fig.3f).
