Ethrel과 CaNO_3의 處理가 포도 Campbell Early의 熟期에 미치는 影響 = Effects of Ethrel and CaNO_3 treatment in Promoting the ripening time of grape, Campbell Early

국문 초록 (Abstract)

本 調査는 Ethrel 單用 및 硝酸칼슘加用 Ethrel 處理가 葡萄 Campbell Early 果實의 熟期 및 品種向上 等에 미치는 影響을 調査하기 위하여 實施하였던 바 다음과 같은 結果를 얻었다.
1. Ethrel과 CaNo_3의 處理가 葡萄 Campbell Early의 時期別 完熟果 收量에 미친 效科를 比較한 바 無處理區에 比하여 熟期促進의 效果가 認定되었고, 特히 熟期促進의 效果가 있었던 것은 Ethrel 500×CaNo_3와 E. 1000×CaNo_3加用이 葡萄의 熟期促進에 有效한 것으로 나타났다.
2. Ethrel과 CaNo_3가 葡萄의 糖度에 미친 影響을 比較한 바 無處理區에 比하여 糖含量이 높으나 着色度에 比하여 顯著하게 糖含量이 뒤 따르지 못하였다.
3. Ethrel과 CaNo_3가 葡萄 pH에 미친 影響을 調査한 바 無處理區에 比하여 酸度가 增加하여 5% 水準의 有意性이 있게 增加했고, 藥劑撒布한 區間의 差는 大同少異하게 나타났다.
4. Ethrel과 CaNo_3가 葡萄 着色度에 미친 效果를 比較한 바 Hormone加用區가 單用區보다 脫粒이 크게 防止되었다.
5. Hormone類別에 種類가 時期別 송이數에 미친 影響을 보면 無處理區에 比하여 顯著히 송이 數에 增加를 보였는데 이는 熟期促進과 收量增加에 기인한 것으로 생각된다.

These experiments were carried out to clarity the effects of Ethrel and CaNO₃on the ripening time and the quality improvement of grape.
The results are as follows.
1. We camparing the effect that the treatment of Ethrel and CaNO₃had an effect on the ripened grape quanitity, it was admitted that there is effect promoting ripening time. Specially it was appeared that to add Ethrel and CaNO₃and E. 1,000 x CaNO₃was very effective.
2. We camparing the effect that Ethrel and CaNO₃had on influenced upon the sugar degree of grape, sugar content was very high in camparision with being not reated, but apparently sugar content could not be followed in comparision with color degree.
3. We investigating the effect that Ethrel and CaNO₃had an effect on pH of graph, acidity was increased to 5% degree and the difference of sprinkled section was practically the same in camparision with being not treated.
4. We investigating the effect that Ethrel and CaNO₃had ad effect on color degree it was appeared that the section of E. 1,000 x CaNO₃and E. 500 x CaNO₃was effective.
5. We investigating the effect that a kind of hormone had an effect on falling of grape grains, adding the hormone was more effective than simple in preventing it.
6. We investigating the effect that each kind of hormone had an effect on grape bunch numbers, and it is considered that this resulted in promoting grape ripening time and increasing grape bunch numbers.
