Abstract
Commercial value of soybean sprouts should be affected by their morphology includingthe lateral roots. This study was carried out to determine the effect of benzyladenopurine(BA) concentration on growth and morphology of soybean sprouts in order to compare themwith the selling products collected from the markets. Four cultivars (cv. Eunhakong,Pungsannamulkong, Sowonkong, and Junjery) were cultured for 6 days after imbibed for 5hours into different BA solutions (0, 1, 2, 4, and 8 ppm). On the 6th day, hypocotyl lengthwas measured to calculate the composition rate of > 7 ㎝ (A), 4 to 7 ㎝ (B), < 4 ㎝ (C) andnon-germination (D), and the ratio of hypocotyl to root length (H/R ratio) on the base ofhypocotyl length as well as lateral root, hypocotyl diameter, and fraction fresh and dryweights. The composition rates classified with hypocotyl length showed big differencesbetween 4 cultivars in class A and C; Class A, in which cv. Sowonkong and Junjery hadhigher rates than cv. Eunhakong and Pungsannamulkong, was decreased with BAconcentration of higher than 4 ppm, but class C showed the reverse result to class A. Anylateral root was not formed in higher than 4 ppm BA solutions although fewer in cv.Pungsannamulkong and Junjery than in the two other cultivars. Hypocotyl and root lengthswere decreased with increased BA concentrations, and in all BA concentration, hypocotyllength of cv. Junjery was the longest. Hypocotyl diameter, hypocotyl and total fresh weightswere thicker and heavier in 2 to 4 ppm BA concentrations than in the other ones, althoughin case of BA application, cv. Eunhakong and Sowonkong were heavier. The H/R ratios wereincreased with increased BA concentration. The ratios of nearly all the selling productsranged from 1 to 2 ppm when compared to them from our experiment.
