Fig. 2.

Gas exchange patterns for Y. aloifolia, Y. filamentosa, and Y. gloriosa across all days of the growth chamber dry-down. Filled circles indicate the clone kept under well-watered conditions, open circles indicate clones which were subjected to dry-down starting after day 1. The open bar indicates hours under light; the filled bar indicates time when lights were off. Points represent averages across all genotypes measured for a given species, with standard errors (too small to be visible for some points).
