  • Soybean, azuki-bean and mungbean were cultivated at different growing conditions, May 10, June 9, July 9 seeding, and May 10 seeding-short day treatment, to investigate the distribution of flowering date and the variation of pod/flower ratio. The growth habit type of the soybean variety used was determinate, but the azuki-bean and mungbean varieties used showed indeterminate growth habit. The pod/flower ratio ranged 38 to 48% for soybean, 23 to 34% for azuki-bean and 46 to 60% for mungbean along with growing conditions. Flower abscission for soybean and mungbean, and pod abscission for azuki-bean affected more on the number of matured pods. Soybean showed once full blooming period, but azuki-bean and mungbean showed two or three times full blooming period except July 9 seeding plot through the whole growing period. Flowers bloomed just after every full blooming period showed lower value of pod/flower ratio and higher pod/flower ratio was obtained from flowers bloomed before or far after full blooming at plots seeded May 10 and June 9 in three pulse crops. Most full blooming period of soybean coincided within 5 days near the terminal leaf appearance date, and number of flowers bloomed before terminal leaf expansion and matured pods from these flowers were major in every soybean plant at all growing codition plots. No relations were found between terminal leaf appearance and flowering or pod setting patterns of azuki-bean and mungbean.

  • The purpose of this study was to evaluate the yield, antioxidant content, and antioxidant activity of adzuki beans according to germination time. Cultivated varieties were Vigna angularis var. Nipponensis cv. Chungju-pat (CJP), and Yeonduchae (YDC), and Vigna radiata (L.) R. Wilczek cv. Dahyeon (DH). The moisture, crude protein, calcium, and magnesium contents of YDC significantly changed with increasing germination time, whereas potassium, natrium, and aluminium contents did not significantly change. Sprout yield, total polyphenol, flavonoid, and tannin contents of ethanolic extracts from adzuki and mung beans significantly increased with increasing germination time. Total polyphenol contents of ungerminated CJP, YDC, and DH were 1.96, 2.68, and 2.02 mg/g, and those of CJP and YDC germinated for 144 h were 3.33 and 3.47 mg/g, respectively. Total flavonoid content of adzuki beans substantially decreased with increasing germination time. Total tannin content substantially increased with increasing germination time, and YDC showed higher contents (0.85 mg/g) sample germinated for 120 h. DPPH radical scavenging activities of CJP and YDC substantially decreased with increasing germination time, whereas that of DH increased. ABTS radical scavenging activities of ungerminated CJP, YDC, and DH were 4.57, 6.51, and 2.82 mg/g, respectively, and increased after germination for 72~120 h.

  • Some minor Korean beans including red bean, mung bean and kidney bean were subjected to proximate analysis, fractionation by the solubility method and polyacrylamide gel disc electrophoresis of proteins to obtain the following results. 1) Proximate composition of the beans showed that fat content was less than 1%, carbohydrate was about 60% and protein content was in the range of $20{\sim}25%$. 2) Total globulin content of the proteins was $46{\sim}59%$, a little lower than in soybean, in the order of mung bean> kidney bean> red bean. Albumin content was comparable in kidney bean, and lower in red bean and mung bean as compared with that in soybean. Glutelin content was relatively higher, being in the range of $10{\sim}19%$ and in the order of red bean> mung bean> kidney bean. 3) According to the electrophoretic pattern, total protein fractions extracted with pH 7.6 buffer from red bean, mung bean and kidney bean showed 9.12 and 11 bands, respectively, whereas those extracted with pH 4.8 buffer showed 13, 13 and 12 bands, respectively. Water extracts of red bean, mung bean and kidney bean showed 10, 8 and 9 bands, respectively, while albumin fractions showed 8, 9 and 7 bands and globulin fractions, 4 bands in all of three beans. The band having a Rm value of $0.5{\sim}0.7$ in the globulin fraction from three beans was not observed in the water extract and appears to be specific to water insoluble globulin.

  • Among the seven taxa of the genus Vigna, Leguminosae vegetated in Korea peninsula, only two taxa, V. unguiculata subsp. unguiculata and V. vexillata var. tsusimensis, are recognized in Vigna. The rests are still remained in the genus Phaseolus in many floras and illustrations of Korea although they were placed into the genus Vigna by Verdcourt in 1970. There has been misidentification between V. angularis var. nipponensis and V. nakashimae because of their similar morphological characters and habit. It was also found that V. nakashimae has not been recorded in many floras. Objectives of this study are 1) to discuss the taxonomic differences between Vigna and Phaseolus, 2) to have a recommendation for using correct scientific names of Vigna taxa, 3) to discuss the taxonomic characteristics of the subgenus Ceratotropis, and 4) to provide a simple taxonomic key of V. angularis var. nipponensis and V. nakashimae.

  • Artificial interspecific matings between Matsumuraeses phaseoli and M. falcana (Lepidoptera: Tortricidae) were conducted to know the possibility of hybridization of the two sympatric species. Reciprocal crossings successfully produced F1 hybrids. Most of F2 crosses yielded progenies except all mating trials with females of F1 hybrid obtained from M. phaseoli female. Inbreedings of the F2 hybrids produced F3 progenies. In backcrossings between F1 hybrids and parent lines, all the two mating trials with females of F1 hybrid obtained from M. phaseoli females did not produce any progeny, while other 6 backcrosses produced the next generations. Inbreedings of the backcross lines also produced subsequent progenies. These results indicated that F1 females produced from hybridization between M. phaseoli females and M. falcana males were sterile. Conclusively, it suggested that a partial reproductive isolation at a postzygotic stage can occur between the two sympatric species.

  • We evaluated the antioxidant properties of adzuki beans and the quality characteristics of sediment using various cultivation methods. There were significant differences in total polyphenol and flavonoid contents in beans grown using different methods of cultivation (p<0.05). Also, DPPH and ABTS radical-scavenging activities were significantly different depending on cultivation method (p<0.05). The sediment yield before drying of Chungju-pat, Hongeon, and Arari was 296.64~339.01, 271.36~282.24, and 268.21~292.32%, respectively, and the sediment yield after drying was 71.68~85.41, 77.90~85.19, and 74.15~78.65%, respectively. The L-value of Chungju-pat and Arari sediments revealed a significant difference given different cultivation methods (p<0.05), but Hongeon sediment did not show a significant difference. There was a significant difference in the a- and b-value of adzuki bean sediments cultivated using different methods (p<0.05). The particle size of Chungju-pat, Hongeon, and Arari sediments was 66.21~98.80, 61.62~97.07, and $82.96{\sim}106.71{\mu}m$, respectively, and all were significantly different depending on cultivation method (p<0.05). There were also significant differences in the water absorption index, water solubility index, and swelling power when different cultivation methods were used (p<0.05).

  • Physicochemical properties of milled rice, brown rice, pearled barley, wheat, sorghum, foxtail millet, soybean, and adzuki bean were evaluated for the production of extrusion formed multi-grain. Grain flours showed large differences in chemical composition including starch, protein, fat, ash, and total dietary fiber contents. Grain flours were brighter in the following order of milled rice>pearled barley>soybean>brown rice>wheat>sorghum>adzuki bean>foxtail millet, and most of the grain flours showed red-yellowish color. Mean particle sizes of grain flours were different among various grains, and whole grain flours tended to have coarser particle size than milled grain flours. The amounts of damaged starch in cereal flours were varied from 5.4 to 10.9%, and limited amount of damaged starch was present in legume flours. Water absorption index of grain flours was, in decreasing order, adzuki>bean>milled rice>brown rice>sorghum>wheat>foxtail millet>pearled barley>soybean. Water solubility index was higher in legume flours containing high protein content.

  • In order to compare physicochemical properties of aqueous extract in 3 beans (small red bean, mung bean, black soybean), proximate composition, free sugars, free amino acids, minerals, absorbance and surface refractance color were investigated. Regardless of raw materials composition, the 3 beans extracts had similar proximate compositions. Free sugar analysis showed that fructose, glucose, sucrose, maltose, raffinose and stachyose were varied among the extracts. Raffinose and stachyose were the major sugar and fructose was measured only in black soybean and glucose was merely found in small red bean. Seventeen free amino acids in beans extract were analysed in the extracts. Among the free amino acids, arginine, aspartic acid, glutamic acid and serine were the main amino acids. Black soybean extract had maximum absorbance at 460 nm and 540 nm. L value of black soybean extract was lower than those of small red bean and mung bean.
