산지(영천군 청통면 신원리), 평지(영천군 신령면 연정리) 강변지(영천군 금호읍 냉천동)의 과수원에서 각각 '후지'과실을 채취하여 대구시 인근의 과실품질을 조사하였다. 결과는 다음과 같다. 1 각 지역 공히 품질이 평균적인 과실을 채취하였고 강변지 과실 중량이 40g정도 작았고, 과실종경 최소치가 다른 지역에 비해 작았다. 평지 과실의 횡경은 최대치, 최소치 모두 산간지보다 큰 것으로 나타났다. 과형지수는 강변지 과실이 다른 지역에 비해 편원형이었다. 이러한 과형의 차이는 온도, 토양수분함량 등에 의한 것으로 생각된다. 과실 착즙률은 각 지역간 유의한 차가 인정되지 않았다. 2. 각 지역 공히 후지과실 전당의 50%정도가 프락토즈인 것으로 나타났고, 산지의 슈크로즈, 프락토즈, 솔비톨 함량이 다른지역에 비해 높은 수치를 나타내었으나 글루코즈는 다른 지역에 비해 낮은 수치를 나타내었고, 당도는 전당함량과 거의 같은 수치를 나타내었다. 3. 각 지역 공히 후지과실 전산의 98% 정도가 능금산이었고 시트르산이 2%를 차지하였다. 산지과실의 능금산 함량이 다른지역에 비해 높은 수치를 나타내었고 적정산은 전산함량과 거의 같은 수치를 나타내었다. This investigation was attemped to know fruit quality of apple 'Fuji' grown at three different areas of Taegu. Fruits were gathered from hill side area : Kyungsangpookdo yongchongun chongtongmynn synwonri, flat area : Kyungsangpookdo yongchongun synyoungmyun youujeongri and river side area : Kyungsangpookdo yongchongun kewmhoyeub naenhchundong. Results were as follows: 1. In fruit sampling, we made an effort to select the same size of fruit from all areas, However, the size at river side area was about 40g lighter and minimum length was shorter than those of the other areas. On the other hand, maximum and minimum diameter of the fruit at flat and river side areas were longer than hill side area. Accordingly, shape index of the fruit in river side area was flatter than the other areas. This difference may be due to temperture, soil moisture content, etc. In squeeze rate of the fruit, no significant difference was recognized among areas. 2. Though, rate of fructose in total sugar was almost 50% in all areas, sucrose, fructose and sorbitol concentration of hill side area were higher than the other areas. however glucose was reverse amd brix was almost same as total sugar concentration. 3. Rate of malic acid in total acid was almost 98% and citric acid was only 2% in all areas. Malic acid concentration of hill side area was higher than the other areas and titratable acid concentration was almost same as total acid.

Five autotetraploids of the cultivated rice were crossed to diploid varieties, Lead rice, Tetep, TKM-6, Carreon, IR747 and Mudgo which were resistant to blast, bacterial leaf blight, stem borers and plant hoppers. Twenty one triploids from above crossed were investigated cytogenetically. The average rate of successful crossed between the resistant cultivars and autotetraploids was 1.61 percent. From the morphological point of view awn, giant spikelet, roughness of stem and leaf which reflect polyploidy and hybridization were observed in triploids. The pairing modes of chromosome in the first metaphase (MI) in P.M.C. depended on the lines; two lines had a mode of 11 III+1 II+1 I, eleven lines 10 III+2 II+2 I, six lines 9 III+3 II+3 I, and two lines 8 III+4 II+4 I. The average number of trivalent per cell was in the range of 8.08 to 10.06. Lagging chromosome, abnormal tetrad and non-simultaneous division mere also observed.

The authors studied on the germination of hard coated pyracantha seed. The seeds were treated with gibberellic acid, concentrated sulphuric acide, chilling, hot water soaking and soaking in water. The results obtained are summarized as follows: 1. Germination rate were increased by hot-water soaking, gibberellic acid treatment and concentrated sulphuric acid treatment, while decreased by chilling and soaking in water. 2. Decreased germination rate by chilling and water soaking can be increased by concentrated sulphuric acid treatment. 3. Maximum germination rate was 19-24% in control, 28%in gibberellic acid treatment, 52% in sulphuric acid treatment and 91% in hot-water treatment. 4. Most effective temperature and duration for hot-water treatment was 30 to 90 minutes at 40℃. 5. Germination rate was lowed at 30℃ than 20℃ at seed bed.

Coast forest vegetation of west side in Choongnam province was studied to explain the structure, quantity of vegetation and differential species for vegetational classification. 1. 5 observed areas were physiognomically devided. 2. QS between the areas were about 60, but were not similar cut-over area and mixed stand among them. 3. Major parts of life form spectrums were Macrophanerophyta and Geophyta. 4. Differential species of the areas were as follows; 1) Pinus densiflora-type: Lespedeza cyrtobotrya, Quercus acutissima, Festuca ovina, Peucedanum terebinthaceum, Aster scaber. 2) Mixed stand: Lespedeza thunbergii, Cocculus trilobus, Quercus aliena. 3) Hardwood stand: Juniperus rigida, Lespedeza cyrtobotrya, Spiraea prunifolia, Carex lanceolata. 4) Cut-over area: Lespedeza maximowiczii, Prunus sargentii, Vaccinium oldhami, Corylus heterophylla, Rhus trichocarpa, Styrax obassia, Viburnum erosum, Lindera obtusiloba, Zanthoxylum schinifolium, Stephanandra incisa, Aster scaber, Scutellaria indica, Polygonatum humile, Platanthera metabifolia, Melampyrum roseum, Vicia nipponica, Hemerocallis minor, Lysimachia barystachys. 5.
