Fig. 3.

(A) ABA content in the aerial organs and (B) in the proximal and distal rhizophore segments (as indicated in the key), and (C) IAA content in the aerial organs and (D) in the proximal and distal rhizophore segments of plants of Chrysolaena obovata at different phenological phases. Values are the means ± s.e. (n = 3). Upper case letters indicate a comparison of proximal segments and lower case letters indicate a comparison of distal segments during the experimental period (P < 0·05). An asterisk (*) denotes a comparison of the segments (proximal and distal) within each harvest date (P < 0·05). nd, no data.
