1. this experiment was made in order to know of the influence of temperature on sprouting and elongation of stem cuttings and runner cuttings of various characters in hop plants. 2. Sprouting process varied with temperature and characters of cuttings. Stem cuttings sprouted earlier than runner cuttings at high temperatures on the whole. But this difference was not so large. Both sprouted at very low temperature. 3. Elongation of sprocets varied remarkably with temperature. At the temperatures below 15°C elongation fell behind, and at higher temperatures above 25°C it was speedy and stems became slender. The temperatures between 17-20°C seemed most suitable for their growth. Stem cuttings grew earlier and stronger than runner cuttings on the whole. 4. At the temperatures lower than 15°C the roots did not grow, while at 17°C and above the root grown were first found. Runner cuttings gave better results in growth of root.
