Abstract
Abstract:The photosynthetic capacity of mature leaves of the epiphytic orchid, Dimerandra emarginata, was studied in plants of different size. There was a linear increase of both area‐based and dry weight‐based rates of O2‐evolution with size by more than 100% from the smallest (1 cm tall) to the largest (50 cm tall) individual. Similar size‐related changes were observed in the leaf nitrogen content but not in the chlorophyll content. The results are discussed in the context of the optimal partitioning theory.
