Fig. 5. (a) Top and root weight of Brown Loam (BL), and the Al-resistant Cycles 1 and 2 (BL-AlR-C1, BL-AlR-C2) and susceptible Cycles 1 and 2 (BL-AlS-C1, BL-AlS-C2) white clover populations derived from it, when grown at two levels of soil pH and resistance index, indicating acid-soil resistance, of those characteristics at pH 4.2. (b) Top and root weight of Huia (H), and the Al-resistant Cycle 1 (H-AlR-C1), the susceptible Cycle 1 (H-AlS-C1), and the acid-soil resistance Cycle 1 (H-ASR-C1) white clover populations derived from it when grown at two levels of soil pH and resistance index, indicating acid-soil resistance, of those characteristics at pH 4.2. Symbols within characters followed by the same letter are not significantly different at the 0.05 probability level. Vertical axis scales have been adjusted so that standard error bars for both characters are approximately equal in size.
