本 試驗은 몇가지 韓國産 무우品種을 供試하여 이들의 生態的인 反應을 生長解析法을 利用하여 檢討하므로써 適正栽培法 및 品種改良을 爲한 基礎資料를 얻기 爲하여 遂行한 結果를 報告한다. 1. 葉面積指數는 發芽後 繼續 增加했고 진주대평무우가 0.34㎡/㎡로 가장 높게 나타났으며 알타리무우가 0.20㎡/㎡로 가장 낮게 나타났다. 2. 最大個體生長率은 2.29g/㎡/day였고, 미농조생무우와 太白무우가 他 品種보다 높게 나타났다. 이들 값은 穀類作物의 個體生長率보다는 훨씬 낮게 나타났다. 3. 純同化率은 生育初期에 높게 나타났고 生育後期에는 낮게 나타났으며 太白무우와 쥐꼬리무우는 Water Stress와 같은 不適環境條件에 대한 適應力이 높은 것으로 나타났다. 4. 相對生長率은 純同化率과 同一한 傾向이었다. 5. 葉面積重量比에서 쥐꼬리무우와 太白무우가 他 品種보다 낮게 나타나 葉이 두꺼워짐에 따라 乾物生産能力이 높게 나타났다. 6. 葉面積指數와 個體生長率, 純同化率은 Watson의 法則과 一致했으며 太白무우의 適正葉面積指數는 0.23㎡/㎡이고, 쥐꼬리무우는 0.19㎡/㎡로서 쥐꼬리무우가 더 빨리 適正葉面積指數에 도달했다. In order to investigate the suitable cultivating practices and varietal improvement in the selected Korean radishes, the analysis of its growth and statistical observation of its growth functions were carried out means of growth analysis. The results obtained are summarized as follows; 1. Leaf area index(LAI) was sharply increased after germination. LAI was highest in Jinjudaepyong radish of 0.34㎡/㎡, but in Altari radish was shown to be the lowest of 0.20㎡/㎡. 2. Maximum crop growth rate (CGR) was 2.29g/㎡/day. Minongjoseng and Taebaek radish were high than the other cultivars. These values were by far lower than those of gramineous crops. 3. Net assimilation rate (NAR) was high in early stage and low in late stage of growth Tabaek and Juikory radish were considered to be more adaptive to unfavorable conditions, especially in water stress. 4. Relative growth rate (RGR) was shown to the same trend with NAR. 5. In specific leaf area (SLA) Juikory and Tabaek radish were lowered than the other cultivars so that the dry matter production showed increases according as the leaf became thicker. 6. The relationships between LAI and CGR, NAR was agreed to the watson's law. Optimum leaf area point(LAI opt.) of Taeback radish was 0.23㎡/㎡, and Juikori radish was 0.19㎡/㎡. Accordingly, Juikori radish was reached at the optimum leaf area point rapidly.

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.

收穫特性이 相異한 園藝作物中 根葉類인 당근과 果采類인 고추를 利用하여 耕耘深度別로 4個處理를 하여 耕耘深度의 差異가 采蔬作物의 生育特性變化에 影響하는 程度를 檢土해서 園藝作物栽培의 省力化 및 經營의 合理化를 期하기 爲하여 試圖되었다. Tractor를 利用한 深耕區, 쟁기를 利用한 慣行區, 耕耘機에 依한 Rotary區 및 除草劑 paraquat를 利用한 無耕耘區로 處理하였다. 그 結果를 要約하면 다음과 같다. 1. 당근은 耕耘深度가 깊을 수록 葉面積, 葉重의 增加를 보였고, 無耕耘區에서는 耕耘區에 比해서 減少하는 傾向이었다. 2. 당근의 根長. 根重은 耕耘深度가 깊을 수록 增加되었다. 無耕耘區에서는 根長과 根重이 極히 減少했고, "hairy root"가 많은 것이 特徵이었다. 3. 당근의 根徑 및 Core徑은 全生育期間을 通해 直善的인 增加를 보였으나 耕耘深度에 따라 有意差가 認定되지 않았다. 4. 耕耘深度別 고추의 側技分化, 莖長, 莖重 및 莖直徑에는 有意差가 認定되지 않았다. 5. 고추의 葉面積, 葉重은 耕耘深度에 따라 有意差는 認定되지 않았으나 無耕耘區에서 生育初기에 增加된 것은 無耕耘의 利点인 土壤水分維特와 養分吸收에 有利하기 때문인 것으로 생각된다. 6. 고추의 根重은 耕耘深度가 깊을 수록 根系發達이 不良하게 나타났고, 收量은 處理間에 有意差가 없었다. 따라서 比較的 淺根性인 果采類栽背에 無耕耘의 利用可能性이 認鄭되었다. The study was conducted to know the compatibility of carrot(Daucus carota L. var. sativa DC.) and pepper(Capsicum annum L.) culture under the various tillage systems as no-tillage(NT), rotary only(RO), conventional tillage(CT), and deep tillage(DT). The DT system seemed to obtain higher index of leaf area and leaf weight than NT. Also the root length and weight of carrot increased with the depths of tillages. This was caused by some advantages in DT system making better conditions for root growth and proliferbtion. Excessive "hairy" root on carrots was detected mainly in the RO and NT systems. However, the stem diameter and core diameter of carrot plants have not showed any significant differences among the tillage depths. Number of branch differentiated of pepper also showed no significances but the early incremint of leaf area and leaf weight from the NT system was considered to be appropriate the soil moisture retention and nutrient uptake as an advantage of NT system. Being a shallow rooted crop, the root weight of pepper plant was readily decreased in DT system where is unfavorable for the proliferbtion of root system. Pepper yields from the treatments with tillage depths showed no significant differences to be concluded for the shallow rooted fruit vegetables have feasibility in use of NT system. Further studies should be followed to know more detailed mechanics on the nutrient uptake, soil type and other problems.
