Functional relationship between leaf/stem pseudobulb size ...

Mar 09, 2022 Water storage has been commonly cited as an important function of orchid pseudobulbs, and it is reasonable to assume that orchids which utilize crassulacean acid metabolism (CAM) photosynthesis have larger pseudobulbs than those of C 3 orchid taxa, because these foliar (or stem) structures may reflect another type of succulent tissue in CAM …
