Abstract
Seedlings of Brassica oleracea var. gemmifera DC. (Brussels sprouts) were grown in four pot sizes over a 4-week period. Whole plant, stem, root and foliage d. wts and foliage area, together with specific leaf area, leaf area ratio and number of leaves initiated were reduced by restricting rooting space. Individual leaves showed similar reductions in d. wt and area, with the effect being more pronounced in later-formed leaves. Cell counts and measurements on the epidermis and palisade mesophyll layers of the first four leaves showed that the reduction in growth was due to reduced cell division. Cell numbers in the first-formed leaf were halved over the range of pot sizes used, and there was a progressively greater reduction in cell numbers in later-formed leaves. There was some tendency for cell size to decrease with decreasing rooting space, but this was not general and was most marked between plants grown in the two smallest pot sizes.
