10 Gooseberry 658 D. B. Carrick The state of maturity and the diameter of the roots were the important factors in determining the resistance to freezing of all species tested in these experiments. The French pear stock seems more tender than the Kieffer stock. Both roots are less resistant to freezing than is the apple. Peach roots on which the variety Elberta had been budded proved les? hardy than the apple and about equal to the Kieffer pear. The order of hardiness of the four cherry stocks t...ested is as follows: Mahaleb, Prunus Besseiji, Primus pennsylvanicum, Mazzard. The Mahaleb stock is considerably superior to the apple, while the Mazzard is about equal to the French pear. Myrobalan plum roots are quite as easily killed by low temperature as are the French pear and the Mazzard cherry. In the six varieties of grapes studied, the roots of the Clinton and the Concord are as hardy as the root of the Mahaleb cherry. The Diamond is slightly less hardy. The roots of the varieties Lindley, Norton, and Cynthiana are more resistant than the root of the Mazzard cherry but less resistant than the apple root.
