EFFECTS OF ENVIRONMENT OF PARENT AND GRANDPARENT GENERATIONS ON TUBER PRODUCTION BY POTATOES

Abstract

W ent , F. W. (Missouri Botanical Garden, St. Louis.) Effects of environment of parent and grandparent generations on tuber production by potatoes. Amer. Jour. Bot. 46(4): 277–282. Illus. 1959.—Potato tubers have very different potentialities of producing tubers on plants of the next generation, according to the growing conditions of the parent plants. When these were grown at cool temperatures, the tuber yield not only of these plants, but also of the following generations, was much higher than when they were grown under warm conditions. Differences in morphology and taste of the tubers as a result of differential temperature treatment of the parent generation are described as well.
