本 實驗은 施設園藝地帶인 光山郡, 順天市, 康津郡 等에서 葉菜類와 果菜類의 育苗用 床土를 試料로 22点 分讓받아 수행하였으며 結果는 다음과 같다. 1.床土의 助成과 性質에 關與하는 가장 重要한 因子는 有機物含量인데 有機物含量이 높아짐에 따라 假比重과 眞比重은 낮았고 空隙率, 水分含量, 全窒素, 置換容量은 높아진다. 2. 葉菜類의 床土는 有機物含量이 많은 반면 果菜類床土의 경우는 그보다 낮게 나타났다. 봄결구배추床土의 有機物含量은 8.85~9.19%의 範圍로 別變化가 없었다. 3. 床土의 pH는 4.9~7.2의 範圍에 있었으며 大部分이 pH 7±1로서 中性에 가까웠다. 4. 置換性 K는 7点이 1.0m.e. 以上이었고 15点이 1.0m.e. 以下로 나타났다. 5. 苗의 바람직한 生育을 위해 P.K.의 量을 規定짓기는 어려우나 床土의 試料內에는 相當量의 養分이 含有되 있는 것을 알 수 있다. This experiment was intended to know the effects of physical and chemical properties of the excellent composts. Twenty two samples were collected from plastic covered greenhouse zone in chonnam province. The results obtained are as follows; 1. One of the most important factors in relation to the texture and other properties of the composts was the organic matter content. The higher the organic matter content were the lower the specific gravity and the apparent specific gravity and the higher the porosity, moisture content, total nitrogen and exchangeable capacity. 2. The composts for raising leaf vegetable seedlings contained higher levels of organic matter while the ones for fruit vegetable contained rather less. The organic matter contents in the composts for spring heading Chinese cabbage were not variable ranging from 8.85 to 9.19 percent. 3. Hydrogen-ion concentrations of the composts were in the range of pH 4.9~7.2 but most of them were in pH 7±1 or nearly neutral in their reaction. 4. Seven samples contained more than l.0m.e. of exchangeable potassium, and fifteen of them contained lower than l.0m.e. of it. 5. It was not clear how high of P or K levels were sufficient for the excellents in some of the samples, at least, were so high, that they seemed to contain surplus amounts of fertilizers.

In order to produce better quality of gladiolus corm, one of the cultivar, Red Beauty was used to find out the effect of plant spacing, planting depth and the levels of nitrogen application on the leaf growth and growth of new corm. 1. Additional 2 cm deep planting required another 2 days to emerge and resulted in 5 cm shorter plant height. 2. Rate of emergence investigated at 25 days after planting showed 100% when planted 5 cm deep. 3. Rate of new leaf production was not affected by planting depth. 4. Leaf area growth, fresh and dry weight and growth of new corm was best when planted 7cm deep. 5. Plant height, leaf area and new corm development showed was best when planted in 20×25 cm dencity with 30 kg / 10a nitrogen.

1. Stem height was 60~65㎝, when the plants were pruned to 1 cluster regardless of cultivar and plant density. Plants with two clusters were 80㎝ high in the density of 4.800 plants/l0a, and 100㎝ high in the densities of 7,200 plants and 1,000 plants/10a. Plants with three clusters were about 100㎝ high in the sparce plantings and 110㎝ in the dense plantings. Plants with four clusters were 120~130㎝ high in all the plant densities. Cultivar Ycungkwang had shorter stems than Daehyung-Boksoo #2 under dense planting. 2. Period of field occupation by tomato plants was 65 days in the plots of 1 cluster harvest and 75, 85 and 110days in the plots of 2,3 and 4 cluster harvest, respectively. 3. The time of first flower was June 23, July 3, July 15, and July 23 in 1,2,3. and 4 cluster cultivation respectively, that is, there was almost one month difference between 1 and 4 cluster cultivation. Difference due to cultivar and plant density was not significant. 4. Total period taken for harvest was 20 days in 1 cluster cultivation compared to 25 in 2 cluster, 35 in 3 cluster and 50 in 4 cluster cultivation. 5. Optimum plant density for highest yield was found to be 7.800/l0a in 1 cluster cultivation and 4,800/l0a in 2 and 3 cluster cultivation and 3,600/10a in 4 cluster cultivation.

서양계 Cymbidium의 경정배양에서 protocorm을 분화시키고 protocorm의 계대배양에서 shoot와 root의 기관 분화와 새로운 protocorm의 형성에 미치는 생장조절제, 영양인자와 비영양인자의 영향에 대하여 실험한 결과를 요약하면 다음과 같다. 1. Cymdidium의 경정조직배양에서 protocorm의 형성까지는 MS기본배지에서 8∼10주가 소용되었다. 2. MS의 기본배지에서 NAA 0.5 ppm과 BA 1.0 ppm를 혼합첨가한 것이 protocorm의 형성에 가장 효과적이다. 3. protocorm의 계대배양에서 기관분화는 NAA 0.5ppm과 BA 1.0ppm을 첨가한 배지에서 양호하였다. 4. glucose 2%와 sucrose 3%를 첨가한 MS기본배지에서 기관분화가 양호하였다. 5. NO₃-N태 질소원이 부정아와 부정근 분화와 생장에 유리하였다. 6. 활성탕의 첨가량은 1%수준이었고 경정 pH는 5.8이었다. 7. 부정아 형성에서 24시간 명배양이 유리하였고 부정근과 protocorm형성에는 12시간의 조명이 효과적이었다. Shoot tip culture of orchids is mainly practised to rapidly propagate homogeneous clones rather than the production of virus-free stocks. In the shoot tip culture of Cymbidium, the protocorms obtained was used to investigate the effects of growth regulators, nutritive and non-nutritive factors on the organogenesis. The results obtained are as follows. 1. In the shoot tip culture, the formation of protocorm required 8∼10 weeks and MS medium supplemented with NAA 0.5 ppm, BA 1.0 ppm was most effective. 2. The concentration of 0.5 ppm NAA and 1.0 ppm BA resulted in good organogenenesis from protocorm. 3. Out of sugars tested, glucose 2% showed the best result in terms of organogenesis . In addition, the sucrose concentration of 3% appeared to be optimum. 4. There was no effect of different nitrogen sources on the protocorm formation. However, the formation of adventitious shoots and roots was facilitated by the addition of NH₄NO₃or NaNO₃at 5 mM, respectively. 5. Activated charcoal was effective in the formation of adventitious shoot with the concentration at 1%. 6. Optimum pH of medium for organogenesis was 5.8. 7. Photoperiod effects on the differentiation of organs. Results showed that 24 hours for adventitious shoot and 12 hours for protocorm was effective.
