DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) The previously reported activity of benzyladenine and selected other cytokinin analogs to increase pod set in soybean (Glycine max) was further investigated to define the structure-activity relationship and evaluate the effects of the cytokinins on yield parameters. Enhancement of pod set was found to be greatest with N-6 satd. alkyl substituted analogs, and was only weakly assocd. with activity in a callus growth bioassay. The response of yield parameters to increasing pod load was evaluated by applying various cytokinin analogs having a range of pod set enhancement activity. The increased pod load at the treated nodes was not compensated by a redn.Except for chemicals metioned above, 67023-51-2 is also used. in pod no. on the remainder of the plant. However, there was a compensatory decrease in seed size. Overall, a significant trend to greater total seed wt. per plant was assocd. with the increased pod no. Initial evaluations indicated that foliar applications of select cytokinins could temporarily increase pod no. However, the increases in pod no. obtained with foliar treatments were too small to be of practical utility and were not maintained to maturity. .
