Stevia의 揷大部位別 試藥處理가 發根 및 收量에 미치는 影響 = Effect of Cutting Type and Clone Type on the Yield and its Germination Root With Stevia

국문 초록 (Abstract)

揷木圃에서 生育한 Stevia의 根群의 形態形成을 알기 위하여 生育部位別 및 發根素處理에서 裁倍된 stevia의 根群을 揷取하여 比較·檢討한 結果를 要約하면 다음과 같다.
1. 天揷穗에서 發根數는 無處理에 比하여 IBA處理區 生育이 2倍 促進되었다.
2. 試藥의 效果에서 IBA處理區는 IAA·NAA處理區에 비하여 揷木된 揷穗에 더 效果的이다.
3. 發根長 및 發根數에 있어서 天揷穗의 IBA處理區가 다른區에 比하여 가장 效果的이었다.
4. 生育 및 收量에서 揷木上部는 揷木下部에 比하여 播種期에 關係없이 約 0.5倍나 增收되었다.

다국어 초록 (Multilingual Abstract)

The formations of root system in Stenia plants was studied by means of an improved monolith method in relation to cutting type: At each growing stage and clone type treatment steuia field.
The following results were obtained:
1. The number of root and length of root of the top stem cutting in IBA growing was to times accelerated at compared with no treatment.
2. The effect of a reagent of IBA treatment plot were effectual to stem cutting than IAA and VAA treatment plot.
3. Length of root and number of root shown IBA plot was most effective than each plot.
4. Growth and yield was about 0.5 times more in the top part cutting plot than the lower part cutting plot regardless of sowing dates.
