• Temperature and photoperiod effects on floral bud growth rates, between detection of a primordium with a dissecting microscope and an open flower, need to be quantified for plant growth and yield models. Plants of several crop and weed species were grown in controlled environment chambers at several daylengths. Degree-day values for bud growth were determined; bud growth rates were much slower under long days in long day sensitive plants. The node at which the first floral bud appeared and total nodes at first flower were also recorded. The soybean strains most sensitive to photopreiod initiated floral buds in a reasonable length of time (50 days, 29/19℃ day/night temperatures), but their floral buds had not opened by the end of the experiment (over 125 days) and it seemed likely they never would. Large floral buds were produced on such plants, but these plants were too large to prevent shading in the growth cabinet.
