Fruit-culture. ipl/ Assuming that an insutlicient mois- ture supply to the fruit, accompanied by great transpiration, may bring about these diseases, it is suggested that the exact method of their occurrence may be through the leaves robbing the fruit of water. Leaves have a higher cell- sap concentration than green fruits and can remove water from the fruits by the process of osmosis. Chandler has called attention to this fact and demon- strated it with detached twigs bearing fruits and leaves. Following Chandler's method fruits have been rapidly wilted, and then, by placing the twigs in water, caused to regain their original state of turgor. In many such fruits spots re- sembling those of drouth spot, and occasionally of cork, were produced. One experiment indicated that a re- duction of the leaf surface of the tree during the critical period might pre- vent the drouth spot, but this is not sug- gested as a practical means of control. The only control method which offers promise of results is one looking to conservation of soil moisture, and an even distribution of the moisture sup- ply throughout the season. Clean culti- vation is not sufficient. From certain suggestions of benefit in the Champlain Valley, and from results secured in the Pacific Northwest, clean cultivation followed by a leguminous cover crop, or the planting of a leguminous crop such a alfalfa in the orchard, seem methods which should be tried. Cer- tain growers in the Champlain Valley are testing them. BETTER FRUIT Page ii The Sun Fruit Drier transforms sunlight into heat, power and motion. A bruised apple is a ruined apple.
