The later graph falls more rapidly than the earlier one, however, which suggests, as in the case of Coleus, that incipient drying was more pronounced in the second series. The lower maximum for the second series may denote lower transpiring power, perhaps partly due to hardening, etc., of the older leaves and partly to incipient drying and actual wilting, which occurred with hours 12 to 16, as sh
