Show FALL PLANTING IS ADVISED Tree Is Capable of Responding to Call for Quick Establishment of New Ront System. (By PROF. WHITTEN, Missouri.) It seems to me that the tree is capable cap-able of responding to the call for quick establishment of new root system when it is transplanted in the fall and that the available plant food, which is stored and carried over in a 6table condition con-dition in the roots, is partly used in the autumn to meet the demand for a new root syste-m or for the healing of wounds. Observations made on spring transplanted trans-planted trees showed that they do not quickly begin to make new roots in spring. They are out in full leaf and apparently making good progress above ground before any root growth could be detected below ground. It seemed a6 if the readily available stored food in the trees was carried to the growing points above ground and utilized to make new growth there more readily than it was carried to the wounds of the roots, to make calluses or to make new roots. Root growth did not begin in spring transplanted trees until the soil got quite warm tomewhat late in the season. In fact, root growth below ground did not begin be-gin to form abundantly until June, about two months after the trees had been ' transplanted. Pairs of trees taken up each month during the summer sum-mer showed those transplanted in autumn had much larger root growth than those transplanted in spring. Trees transplanted during the fail of 1909 made a much better growth than did corresponding trees transplanted during the spring of 1910. |
