張田益,金龍湖 濟州大學校 亞熱帶農業硏究所 1992 亞熱帶農業硏究 Vol.9 No.-

재배면적의 증가될 것으로 예상되는 방울토마토에 있어서 그 종자구입의 어려움을 덜고, 또 육묘기간의 단축을 위하여 揷木苗의 이용이 중요과제라 생각되어 Pepe, Pico, Yellow Pico 및 Petit 4품종의 측지를 삽목육모하고, 火山礫인 송이를 培地로 한 養液栽培方法으로 실시한 시험결과를 요약하면 다음과 같다. 1. 養液의 給液水位에 따른 방울토마토의 收量, 形質에는 영향을 주지 않았고 특히 糖度(Brix)도 水位에 따른 差異가 인정되지 않았다. 2. 방울토마토 品種은 Pepe와 Pico가 早熱이면서 多收性이었고 Yellow Pico와 Petit는 다소 늦게 收穫期에 이르렀으며 收量도 적은 편이었다. 3. 糖度 (Brix)는 Pepe와 Picod에서 높은 數値를 보였고 Yellow Pico와 Petit는 낮은 경향이었다. 4. 당도를 높이기 위해서는 송이 培地의 理化學的 特性을 면밀히 조사 분석하고 이를 고려하여 養液의 排液間隔을 조절한다면 可能할 것으로 思料된다. The cuttage seedlings could be used for production of cherry tomato whose acreage was expected to increase. Considering seed cost and reduction of nusery period, evaluated the effects of flooding height of nutrient solution in Scoria medium culture on yield and the other characteristics of cherry tomatoes grown using cuttage seedlings. The results obtained are summarized as follows; 1. The fruit yield and sugar concentration (Brix Scale) including the other characteristics were not by the flooding height of nutrient solution. 2. Compared to "Yellow pico" and "Petit", "Pepe" and "pico" matured earlier and high yielding cultivars. 3. Sugar concentration in "Pepe" and "Pico" was higher than in "Yellow pico" and "Petit". 4. Sugar concentration of fruit juice could be increased by controlling drainage interval of nutrient solution considering physical and chemical characteristics of Scoria

The effects of KCl and NaCl levels on early growth of 'Aomori' garlic plants grown in nutrient solution at the Agricuture and Forestry Center, Tsukuba University were determined to obtain basic information for fertilization method. The results obtained are summarized as follows. 1. The levels of KCl and NaCl did not significantly affect the number of roots and leaves. 2. Length of roots and leaves was greater in plants grown in the nutrient solutions of less than 15mM KCl and 20mM NaCl. 3. Growth of roots and shoot was greater in plants grown in the nutrient solutions with less than 4.0 mmho concerning the EC value. 4. Fresh and dry weights were greater in plants grown in nutrient solution with lower levels of KCl and NaCl. There was no difference among treatments for the dry matter ratio. 5. Shoot growth of garlic was harmless without application of KCl and NaCl in nutrient solution.

마늘에 대한 KCl과 NaCl 의 效果를 究明하여 施肥方法의 基礎資料를 얻고저 寒地型靑森마늘을 가지고 Tsukuba大學 農林쎈타에서 養液栽培方法을 利用하여 試驗栽培를 하였으며 植物體內몇가지 無機性分과 葉綠素를 分析한 結果는 다음과 같았다. 1. 마늘 地上部의 N과 P의 含量은 KCl이 없거나 낮은 濃度에서 많았다. 2. K와 Na의 含量은 KCl과 NaCl의 處理水率에 관계없이 吸收蓄積이 되었는데 KCl과 NaCl을 전혀 施用하지 않은 區에서도 含有되어 있었다. 3. NaCl 施用은 Ca와 Mg의 吸收蓄積에 영향을 주지 않았다. 4. 뿌리의 Na含量은 葉中含量보다 훨씬 많았으며 KCl水準이 높은 區에서 오히려 많았다. 5. 葉綠素는 NaCl 高農度區에서 그 含量이 많은 것으로 보아 마늘에 있어서는 K代身에 Na를 施用해도 栽培가 可能할것으로 期待된다. 本試驗は養液栽培方法を利用して二ソ二クの施肥法改善の基礎資料を得るたぬ寒地型靑森二ソ二クを使用, KClとNaCl組成比率の差異影響に對して, 日本のTsukuba大學農 林セソタ一で1989年7月かち1990年1月まで遂行したものである.試驗遂行にあたり直接設計して下さいました Tsukuba大學農林學係の池田英男先生 ならびいろいろ測定と分析を擔當協力をした留學生池性韓氏 に厚かく感謝を表します. The effects of KCl and NaCl levels on the contents of several elements and chlorophyll in 'Aomori' garlic plants grown in nutrient solution at the Agricuture and Forestry Center, Tsukuba University were determined to obtain basic information for fertilization method. The results obtained are summarized as follows. 1. Nitrogen and phosphorus contents in the top were greater in plants grown in nutrient solution without KCl or with lower KCl levels. 2. Potassium and sodium were absorbed and accumulated in garlic plants regardless of KCl and NaCl levels. Plants grown in nutrient solution without KCl contained KCl and Na. 3. Appication of NaCl in nutrient solution did not affect absorption and accumulation of Ca and Mg in plants. 4. Sodium content was much higher in roots than in leaves and Na content in roots was rather at the higher KCl levels. 5. It is espected that garlic can be grown by application of Na instead of K considering that chlorophyll content was greater at the higher levels of NaCl.

1. In this study, I found that 75cm×18cm (7,200pieces/10a) was the best planting distance of fall-potato between 75cm×18cm (7,200pieces/10a), 75cm×24cm (5,400pieces/10a) and 75cm×30cm (4,320pieces/10a). The species of fall-potato that I examined were Irish Cobbler, Tachibana and Shimabara. 2. In my view for the fall-planting potato, there's no need to fertilize more than N, 14.4kg, P₂O??, 16.8kg and K₂O, 8.8kg per 10a. (for this study I used Tachibana only) 3. The better seed-time of Tachbana and Shimabara for the fall-planting was from 20 to 30 of August. (about August 25).

This study was conducted to evaluste effects of cold storage of seed bulbs and light break on secondary growth and seasonal changes of endogenous ABA and GA like substances in "Sanghai Early" garlic. Before witering, cold storage increasecd activities of GA like substances in garlic. At the middle of April, the growth in bulb diameter, activities of GA like substance were higher but percentage of secondary growth was lower under normal temperature storage than under cold storage plots. Activities of ABA like substances were higher under cold strorage plots than under normal temperature storage plots.

This study was conducted to evaluate the efficacy of soil heating treatment for the control of cabbage yellows. The results obtained are summarized as follows ; 1.The density of Fusarium oxysporum was not changed with time at room temperature while it was not isolated 25 and 5 days after the heating treatment of 35 and 40℃, respectively. However any of it was not detected above 45℃. 2.When cabbage was grown in the soil inoculated with the pathogen after the inoculated soil was incubated for 1, 3, 5 and 7 days at 45℃, Fusarium oxysporum wilt was not observed for cabbage grown in the soil incubated for more than 3 days. 3.Pseudomonas sp. and Bacilus sp. antagonists that show antifungal activity to were Fusarium oxysporum in petri dish assays were isolated. The growth temperature of Bacillus sp. was higher than that of Fusarium oxysporum.

The present experiment was conducted during the period from August 27, 1979 to June 5, 1980, in order to examine the suitable planting time in Jeju Island. The results are as follows : 1. Top part growth increased continuously into the middle of May. After that, it decreased. The earlier the garlic was planted, the higher the plant height, leaf height and leaf width in each plant. 2. In the underground part growth, the earlier the garlic was planted the higher the plant weight, bulb weight, bulb diameter and neck diameter. However, bulb height and neck diameter also showed good growth by 30, October. 3. Because the bulb index was below 0.5 in the bulb formation, no difference showed during the seeding period. 4. The number of primary cloves per bulb (out layer+inner layer) appeared to be similar until 30, Oct, but in the number of secondary cloves there was little difference during the seeding period. 5. The plot of cut seedstalks more than uncut seedstalks increased bulb height, bulb diameter and neck diameter. Both of them appeared similar in bulb formation ratio.

This study was conducted to investigate the influence of Na compounds-such as NaCl, sea water, NaNo_(3), atonic, and borax on the growth of Cheju native garlic (a kind of Southern garlic, short stem) which was grown on Cheju Island. The results of this study were as follows: 1. No influence of Na compounds on the growth and the emergence of Cheju Native garlic after seeding was observed. 2. In the latter part of the growth period, the garlic which had been treated with Na compounds showed the tendency to grow earlier than those which had not been so treated. 3. The results of the analysis of garlic's inorganic substances showed the tendency that the garlic which had been treated with Na compounds contained more salts than those which had not been so treated. Therefore, the writer of this paper could confirm the fact that garlic is one of the crops which needs Na. 4. A more minute investigation and experimentation on the physiological influence of Na on garlic's growth is expected to be conducted in the future.
