The resistance against drying of mulberry (Morus alba L.) graftages lifted in the fall and spring was examined by measuring water loss, survival, and regrowth. The graftages were exposed on the ground an4 covered with 2 sheets of straw mat for 0, 1, 3, 6, 10, and 15 days. 1. Temperatures in the mat ranged from 13 to -6.5$^{circ}C$ in fall and 24 to -2.8$^{circ}C$ in spring. Relative humidity was 37 to 100% in fall and 20 to 100% in spring. 2. Water loss from the graftages was less than 10% after 10 days exposure in fall, whereas there was 9.8% loss with 1 day exposure in spring. 3. Six days exposure in the spring caused the root hairs to dry and the root surface to become wrinkled longitudinally and turn yellowish-red. 4. Maximum exposure which allowed 100% survival and regrowth after planting was 6 days in fall and 3 days in spring under 2 sheets of straw mat.
