- W2028196457 abstract "1. Studies were made of the effects of photoperiod and light intensity upon flower formation in plants of several genetically different populations of castor bean. Plants were grown in soil in the greenhouse, field, or controlled-environment rooms. The node position of the first flowers and the total number of nodes on nonflowering plants were the criteria used for measuring the responses of plants to duration and intensity of light. 2. In experiments concerned with photoperiod alone, marked variation in degree of flowering response was observed for a number of varieties. Some failed to flower on either long or short photoperiods, while those of other varieties flowered on both photoperiods. In the case of one variety, flowers developed only on plants grown with long photoperiod. 3. Plants of two parents and their F1 and F2 progenies, the last of which contained plants that remain flowerless when grown under normal field conditions at Beltsville, Maryland, were grown with controlled photoperiod. Plants of both parents and the F1 progeny flowered at relatively low node positions, the F1 plants being intermediate between the parents in this character. The node position of first flowers on most of the F2 plants was within the range of that of the parents and the F1 progeny, but 10% of the F2, plants remained vegetative under the several treatments given. 4. Flowerless F2 plants remained vegetative when grown with several different photoperiods and likewise when grafted either as stock or as scion with vegetative parent plants which subsequently were induced to flower. 5. Earliness of flowering of parent plants whose F2 populations contain the flowerless character was significantly affected by variation in photoperiod or in light intensity. In the case of one parent, flowering was markedly controlled by a light-energy factor. In this case flora initiation occurred only on long photoperiods applied during spring, summer, and fall. During the short days of winter, flowers failed to form even under a continuous 24-hour photoperiod in which supplementary artificial illumination was supplied." @default.
