TULIP ROOT BEHAVIOUR AND AERATION REQUIREMENTS

L.K. Wiersum
Experiments to investigate the minimum aeration requirement of tulip roots were performed in cylindrical vessels. Aeration was regulated by altering the composition of the gasmixture above the soil. Oxygen supply at different depths in the soil column was checked by oxygen diffusion rate (O. D. R.) measurements. Tulip roots were found neither to require an extra high aeration level nor to be especially sensitive to a short period of anaerobiosis. Depth of root penetration downwards was affected both by O. D. R. -level and soil density.
