Werner, H.O. (1931) The effect of maturity and the ethylene chlorhydrin seed treatment on the dormancy of Triumph potatoes (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 57)


ISSN 0097-1388


Western Nebraska dry-land Triumph potatoes (Solanum tuberosum L.) vary in maturity at the time of harvest, from some that are very immature to others with vines which are entirely ripe. Variations in maturity may be due to such factors as early frost, drouth, destruction of vines by hail or early blight, time of planting, and strain type (whether early or late maturing). The question of seed maturity and its influence upon duration of the dormant period is of considerable commercial importance, since these potatoes are annually being planted in south Texas as early as December 26 and in southern Florida, Bermuda, and the West Indies as early as September and October. In order to supply the most satisfactory seed to these regions it is necessary to determine the facts concerning the duration of the dormant period and the sprouting habits of tubers of varying maturity as well as the influence of such factors as time of harvesting and method of storage upon dormancy. Furthermore it is necessary to know how such tubers respond to the more important chemical methods of terminating the dormant period and how the efficiency of said treatments may be increased or impaired by the method of application.
