In this study, flowers varying in level of pod set were obtained from the semi-determinate, many-flowered line IX93-100 and analyzed for total soluble sugars, transported N compounds, starch and total N. Correlations between percent pod set and chemical composition varied with method of sampling for some substances. Little evidence of nutrient shortage in aborting flowers was seen. Analysis of raceme tissues separately from flowers revealed little evidence of restricted nutrient removal from raceme into the aborting flower except possibly for the transported N compounds. The best association with abortion appeared to be slow growth of the flower.
