  • 꽃은 종에 따라 모양이 크고 작고 뾰족하고 넓으며 색깔도 노랗고 빨갛게 다양하다. 세포액이 산성이면 진달래처럼 붉은 색이 되고 알칼리성이면 도라지처럼 푸른 색을 띈다. 그리고 개나리처럼 노란 꽃은 세포액이 중성일때 나타나며 화청소가 없으면 흰꽃이 된다.

  • This study was carried out to examine the effects of cutting dates and rooting promoters on rooting of the Rhododendron mucronulatum Turcz. The rooting percentage in greenwood cutting was high in June and decreased after July 3, when reproductive growth began. The best rooting percentage(92.5%) occurred when cutting was completed on June 12. There was no difference in rooting potentials between the greenwood straight cutting and the greenwood heel cutting. Cuttings of R. mucronulatum for. albiflora showed high rooting percentage(85%) similar to the cuttings of R. mucronulatum. Dipping cuttings in NAA $2,000mg{\cdot}L^{-1}$ solution for 15 sec increased the rooting percentage up to 97.5%, and also promoted root growth.
