Table4. 5 : 二十日무우와 Burpee White' French Break Fast를 根重 葉重 收量에서 比較한 結果 品種間의 有意性이 없으므로 Burpee White' French Break Fast는 二十日무우와 別差없이 端境期 栽培 品種으로서 可能性이 있다고 본다. From an experimental growing of the Early Deep Scarlet Radish during the unproductvc summer season, and a comparison in productivity between the Early Deep Scarlet Radish and some imported varieties the following results are known; 1) Table3. Even though the Early Deep Scarlet Radish cultivated during the unproductive summer season is a little inferior in the length of its leaf and root to that raised during the proper season it is worth raising during the unproductivesea son to meet the demands when vegetables are scarce. 2) Table4. 5. Theccmparison of the Early Deep Scarlet Radish, Burpee White, and French Break fast in their weights of their leaves, roots, and harvest has indicated that there is not significant difference between the species. So, Burpee White and French Break Fast, as well as the Early Deep Scarlet Radish, may be profitably cultivated durng the unproductive interval summer season.

As a result of the Test conducted to studs the exact training and topping method on the PRINCE MELON, I have obtained some data. The following is the summing-up of those results : 1. In the length & diameter of the fruit, the topped item with one leaf left from the sub-main branch, which was out of the topping,20 nodes of the main branch, has been the highest. And there was a positive correlation between the length and the diameter of the fruit. 2. The minute spots in the fruit have been revealed to be the minimum in the topped item with one leaf left from the sub-main branch, which had been out of the topping, 20 nodes of the main branch. 3. The amount of sugar contained in it was 15%, which was the highest for the topped item with six leaves left from the sub-main branch, which had been out of the topping, 20 nodes of the main branch. 4. In the cracked fruit, the topped item with one leaf left from the sub-main branch, which had been out of the topping,8 nodes of the main branch, was higher in number. The size of the hilum had nothing to do with the training method. 5. The average weight of the fruit indicated that there was a significant difference of 5% level, as compared with the topped item with 3 leaves left from the sub-main branch which had been out of the topping,20 nodes of the main branch. 6. The topped item with 6 leaves left from the sub-main branch, which had been out of the topping, 8 nodes of the main branch, was a little bit higher in the total amount of the quantity.

Ethephon과 Gibbrellin 處理가 오이의 性發現과 이에 따른 蛋白質含量, Peroxidase活性 및 Isoperoxidase Pattern에 미치는 影響

具禹書,金暎來 충남대학교 농업과학연구소 1985 農業技術硏究報告 Vol.12 No.1

This experiment was conducted to study sex expression and subsequent changes in protein and peroxidase after three cultivars of cucumber plants were treated with ethephon and gibberellin. The three cultivars of cucumber used in this study included 'Sayeup' (monoecious type), 'Sinrokdadaki' (gynoecious type), and 'Seonghowon' (intermediate type). The ethephon at 250ppm and gibberellin at 100 ppm were treated at the 2-leaf and 4-leaf stages, and subsequent sex expression and changes in protein contents, peroxidase activities and isoperoxidase banding patterns by disc polyacrylamide gel electrophoresis were studied. The results can be summarized as follows: 1. Ethephon treatment slightly increased number of pistillate flowers and significantly decreased number of staminate flowers in the three cultivars, while gibberellin treatment significantly increased number of staminate flowers in both gynoecious 'Sinrokdadaki' and intermediate 'Seonghowon' and did not increase number of staminate flowers in monecious 'Sayeup' 2. There were some differences among three cultivars in protein contents, protein banding and isoperoxidase banding patterns of seeds and germinating seeds, However, it was not obvious to differentiate monoecious from gynoecious cultlvars by these characters. 3. Protein contents in the leaves and stem apex after ethephon and gibberellin treatment increased gradually at the 2-leaf stage, but decreased at the 4-leaf stage. Protein contents in stern apex at the 4-leaf stage without treatment were much higher in 'Sinrokdadaki' and `Seonghowon' than in monoecious 'Sayeup'. Protein contents in the stem apex at the 4-leaf stage were increased in the ethephon-treated monoecious 'Sayeup' and decreased in 'Sinrokdadaki' and 'Seonghowon' compared with untreated plants. 4. Peroxidase activities in the leaves and stem apex gradually decreased at the 2-leaf stage, but increased at the 4-leaf stage. Peroxidase activities in stem apex at the 4-leaf stage were significantly increased by ethephon treatment. 5. The number of protein bands in the three cuitivars after treatment gradually decreased in leaves and stem apex at the 2-leaf stage, but increased in the 4-leaf stage. The protein banding pat terns of stern apex of the ethephon- treated monoecious ' Sayeup' at the 4- leaf stage were gradually shifted to the banding

Gibberellin 處理時期를 앞당기고 cellophan紙 袋覆를 하면 無核率이 높은 反面 果粒數 果重이 減少되고, Gibberellin 處理時期를 늦추고 新聞紙 覆袋를 하면 果粒數 果重은 增加하지만 無核率이 낮아졌다. The results obtained by the Gibberellin and bagging treatment on the Campbellearly grape are as follows: 1. The suitable period of treatment for cluster weight and number of berry are to be before 8 days of full bloom. The cluster weight was 76.4% and number of berries were 80.6% compared with control. 2. The ratio seedless berries of 92% per cluster, and number of 12 seedss in 100 beries were showed the best on before 18 full bloom at the bagging plots of Gibberellin treatment+cellophane paper. 3. Number of berry and number of seed (r=0.826) also were showed mutual relation of plus between the number of seed and fruit weight. 4. Soluble solid was showed higher of 9.3% at the cellophane paper bagging plot and 9.34% at the parchment paper bagging plot than the control. Juice content and ash were showed high at the conthol and newspaper bagging plot, and low at the cellophane paper bagging plot. 5. The content of vitamin C was showed low tendency at the higher of the seedless ratio with the quick Gibberellin treatment period. At the betweentreatment, the control and parchment paper bagging plot were showed much, and showed less content at cellophane paper bagging plot. 6. In advance the period of Gibberellin treatment and had cellophane paper bagging then the ratio of seedless would be high, but on the contrary, the number of berry and fruit weight decreased, and had delay the period of Gibberellin treatment and had the newspaper bagging, the number of berry and fruit weight would be increased but the ratio of seedless was low.

오이는 性發現에 관한 基礎資料를 얻고져 飛節成種인 四葉과 節成種인 신록다다기, 그 中間形인 聖護院을 공사하여 種子와 崔芽종자의 蛋白質含量의 品種간 차이와 子葉展開期의 ethephon(250ppm)과 Gibberellin(100ppm)處理에 의한 蛋白質 含量과 peroxidase活性의 變化, 蛋白質 banding pattern 및 perosidase isoenzyme의 banding pteern의 變化 關係를 調査하여 다음과 같은 結果를 얻었다. 1) 種子와 崔牙種子인 蛋白質含量, 蛋白質 banding pattern 및 peroxidase의 banding pattern에서 飛節成과 節成品種간에 뚜렷한 차이를 볼 수 없었다. 2) 子葉期의 蛋白質 含量과 蛋白質 banding pattern에서는 3品種 모두 ethephon處理區에서 蛋白質含量이 높았고, 蛋白質 banding pattern에서는 處理 後 日數가 지남에 따라 變異를 보이다가 處理後 5日째 四葉의 ethephon 處理區의 Rf 0.33-0.34의 位置에 强度높은 band가 形成되었으며, 聖護院, 신록다다기의 無處理區에서 形成된 band의 位置와 强度가 同一하였다. 3) 子葉期의 peroxidase 活性 및 peroxidase banding pattern에서는 ethephon處理區에서 3品種 모두 peroxidase activity가 높게 나타났으며, ethephon 處理後 1일째는 3品種 모두 거의 같은 band의 樣相을 나타내었고, 處理 後 3일째는 變化의 樣相을 보이다가 處理後 5일째는 四葉의 ethephon 處理區와 聖護院, 신록다다기의 control區가 거의 같은 banding pattern을 나타내었다. This experiment was conducted to obtain the basic information the patterns of change in protein contents, peroxidase activity and of sex expression between three cucumber varieties(monoecious type;Sayeupl gynoecious type; Sinrokdadaki, intermediate type; Seonghowon) by treating ethephon with 250ppm and gibberellin with 100ppm at the maturing stage of their cotyledons. The patterns of changes in protein contents and peroxidase activity were analyzed using disk polyacrylamide gel electrophoresis and the results are summarized as follows. 1. No difference was found in changes of the protein contents, band pattern of peroxidase and iso peroxidase activities between mature seeds and germinating seeds of Sayeup(monoecious type) and Sinrokdadaki(gynoecious type). 2. High protein contents were obtained in cotyledons of all varieties treated with ethephon, and a variety of band patterns of protein isolated were shown on the gel during the initial stages after ethephon treatment. After 5 days of ethephon treatment, however, a strong band was observed at the Rf value of 0.33-0.34 on the gel analyzed from the proteins isolated from Sayeup cotyledons with etyephon treatment and the band intensity of their proteins was similar to ones from Seonghowonand Sinrokdadaki with no ethephon treatment. 3. As a result of gel analysis, high activity and strong band of peroxidase isolated from ethephon treated carieties was examined. Similar band patterns of proteins isolated were observed in the cotyledons of all carieties used after one day of ethephon treatment. After 3 days of ethephon treatment, all varieties showed various band patterns, while after 5 days, the band pattern of proteins isolated from ethephon treated Sayeup similar one of proteins from both Seonghowon and Sinrokdadaki with no ethephon.
