Popis: The excellent review by Joyet-Lavergne1 of the earlier work on this problem obviates the need of recapitulation here. It may be stated, however, that the formative responses of the sexes in dioecious plants under various conditions have been much more thoroughly recorded than their concomitant physiology. This investigation was undertaken in an attempt to secure comprehensive data concerning normal staminate and pistillate metabolism in typical dioecious plants. For comparison of long and short day photoperiodic responses, data are presented for spinach and hemp as representative of these two types.Plants were grown in the greenhouse in the early spring and summer in triplicate series which were thinned to between 50 and 100 plants each, depending upon the age at which they were to be analyzed. The vegetative-reproductive cycle was controlled by supplementing daylight with electric light as needed at the rate of two 100-watt lamps per square yard at the height of one foot above plants. It was necessary to...
