고구마 품종 '율미'를 이용해 2,4-D 1.0 mg/L가 첨가된 MS 배지에 정단분열조직배양을 통하여 발생된 배발생 캘러스를 실험재료로 여러 가지 동결보호제를 처리하여 2-step method 에 의해 동결보존을 실시하였다. ABA 10m/L가 포함된 배지에서 전처리된 배발생 캘러스는 ABA 1.0mg/L 처리구보다 액체질소에 저장 후 생존율이 더 높게 나타났다. TTC방법과 FDA 염색법을 통해 초저온 보존 후에 생존을 확인한 결과 10mg/L의 ABA를 전처리 한 0.4M sucrose가 포함된 1.28M DMSO 처리구에서 46.8%의 가장 높은 생존율을 나타냈다. 캘러스를 1.0mg/L 2,4-D가 포함된 MS 고체배지에서 암배양한 결과 배양 4주일 후부터 1.28 M DMSO 단독처리구에서 캘러스가 생장하는 것을 육안 관찰할 수 있었으며 배양 8주일 후에는 배가 발생하였고, 0.1 mg/L 2,4-D+0.1 mg/L kinetin 혼용구에 2주일간 계대배양한 다음 MS기본배지에서 완전한 식물체로 재생되었다. Cryopreservation of embryogenic callus derived from apical meristem culture was attempted by slow prefreezing method (two-step method) with various cryoprotectants in sweetpotato cv. 'Yulmi' Precultured embryogenic calli on medium containing 10 mg/L ABA prior to slow prefreezing in liquid nitrogen indicated higher survival rate than 1.0 mg/L ABA preteatment. The cryoprotectant comprising 1.28 M DMSO in 0.4 M sucrose solution gave the best survival (over 46%) of sweetpotato cells exposed to liquid nitrogen as determined by TTC reduction and FDA staining method. Cryopreserved calli cultured on MS medium with 1.0 mg/L 2,4-D were grown for 4 weeks in the dark and induced embryos after another 4 weeks. They were subcultured on MS medium supplemented with 0.1 mg/L 2,4-D+0.1 mg/L kinetin for 2 weeks and regenerated into normal plantlets in MS basal medium.

Acoustic telemetry is used to obtain a relatively continuous record of fish movement. This method has several advantages for studying migrating fish populations that are moving from large rivers. The Nakdong River is the longest river in South Korea and the main stream has faced a change, which consists of the installation of the large weirs. In this study, we applied acoustic telemetry to monitor the movement pattern of Erythroculter erythropterus (family Cyprinidae) and identified home range and movement distance in the Nakdong River. A total of fourteen individuals were released at three different locations and around 80 km section from the estuary barrage was investigated. Eight individuals were tagged and released at estuary barrage (N02) utilized up to 15.9 km (home range) upstream from the release site as home range. Four individuals were tagged and released at Samrangjin (N07), most fish moved and stayed within 9.7 km (home range) downstream area, except E12, which did not show any movement. Two individuals were tagged and released at Changnyeong- Haman weir (N10), and all individuals migrated downstream from the release site. Especially, E14 recorded the longest accumulated detected distance, 36.7 km downstream during 32 days after release. There was no correlation identified between movement (accumulated detected distance and home range) and standard length (Spearman rank correlation, p¤0.05). Although, this technique could be an available method to monitor behavior and ecology of freshwater fish effectively, increment of number of receivers and tags are required for more detailed results of fish migration.

Visual monitoring is hard to apply on fish because they are living in a water system. To overcome this problem, acoustic telemetry, which is effective for underwater monitoring, is often used for studying fish behaviors, such as movement distance, route and patterns. In this study, in order to monitor the movement pattern of Squaliobarbus curriculus (family Cyprinidae), we used acoustic telemetry and identified the home range and movement distances. A total of nine individuals were released at two different locations: one is at the estuary barrage (Sc1~~3) and the other is at the lower part of Baekjae Weir (Sc4~~9), located in Geum River. Approximately, a 70 km section from the estuary barrage was investigated. Fish, which were released at the estuary barrage, utilized up to 12.7 km upstream as home range from the release site. At the lower part of Baekjae Weir, most of the fish moved and stayed within a 7.2 km downstream area, except for Sc6, which moved 53.4 km (linear maximum distance from release site) downstream from the release site. Relatively small sized fish (Sc7~~9) did not show any movement. Accumulated movement distance significantly correlated with the standard length of S. curriculus (rs=0.715, p=0.03). Moreover, the standard length of moving fish was significantly larger than that of not moving fish (Mann- Whitney U test, p=0.024). Therefore, the movement distance of S. curriculus has been correlated with fish size; movement distance was increased with the standard fish length. Although the sample size of monitored fish was small, various meaningful data were collected by acoustic telemetry. Consequently, this technique could be a method available for effectively monitoring the behavior and ecology of native Korean and endemic species.

Karyotypes of four Lycoris species, L. aurea, L. squamigera, L. koreana and L. radiata, was studied. The basic chromosome numbers of the diploid plants, L. aurea and L. koreana were x=8 and x=11 and those of triploids, L. squamigera and L. radiata were x=9 and x=11, respectively. The chromosome complement of L. aurea was composed of 3 pairs of large metacentrics, 1 pair of submetacentrics and 4 pairs of telocentrics. The karyotype of L. squamigera was 2 pairs of large metacentrics, 3 pairs of subtelocentrics and 4 pairs of telocentrics. The karyotype of L. koreana was 7 paris of subtelocentrics and 4 pairs of telocentrics and that of L. radiata was 3 pairs of subtelocentrics and 8 pairs of telocentrics. No large chromosome was found in L. aurea and L. koreana Supernumerary segment was found in chromosome 1 of L. koreana. Chromosome 4 of L. radiata carries satellite.
