Entrance of Water Into Suberized Roots of Trees

Results of several investigators (1,2,3,4) suggest that the absorbing area of root systems may not be restricted to young roots and the young terminal portions of older roots, but that older suberized portions may account for a considerable amount of the water absorbed.By means of potometers HAYWARD, BLAIR, and SKALING (2) demonstrated an appreciable amount of absorption by suberized roots of sour orange.KRAMER (3) has made a comparative study of rate of absorption by suberized roots of several different species.The present experiment was undertaken to determine the avenues of entrance of water into suberized roots.
