Chloroplast Distribution in the Stems of 23 Eucalypt Species.

Small diameter branchlets and smooth barked stems and branches of most woody plants have chloroplasts. While the stems of several eucalypt species have been shown to photosynthesise, the distribution of chloroplasts has not been investigated in detail. The distribution of chloroplasts in branchlets (23 species) and larger diameter stems and branches with smooth bark (14 species) was investigated in a wide range of eucalypts (species of , and ) using fresh hand sections and a combination of bright field and fluorescence microscopy.
