SUMMARY Supplementary carbon dioxide increased the growth rate of cucumber ( Cucumis sativus , variety Butcher's Disease Resister) in pots in a glasshouse, by increasing both net assimilation rate and leaf expansion. It increased areas of individual leaves by increasing their growth rate before they emerged from the terminal bud. Growth rate after emergence was unaffected by CO 2 concentration. When the pots became full of roots, increasing CO 2 concentration had less effect on leaf growth, probably because of indirect effects of restricted root growth.
