Abstract

In this study, the morphological characteristics of flower and fruit in five varieties (Hancho 915ho, 930ho, 10ho, 1020ho, 1030ho) from Zanthoxylum schinifolium were investigated as new varieties with different fruiting seasons. Qualitative and quantitative characteristics were investigated, spectively. For quantitative characteristics can be measured numerically, such as size and number, the varieties were identified using ANOVA and Scheffe's multiple range test. In addition, the validity of whether the quantitative characteristics of five varieties can be explained by factor analysis was reviewed. Using UPGMA, the relationship between the five varieties was confirmed by dendrogram. As a result of ANOVA and Scheffe's multiple range test there was significant difference in inflorescence width and female flower length. It had a high contribution to distinguishing varieties, which was similar to the PCA results using factor analysis. As a result of dendrogram using cluster analysis, Hancho 915ho, 1020ho and 1030ho were similar, but there was a distinct difference in the characteristics of different flowering and fruiting periods, confirming that they were different varieties.

산초나무 5개 품종의 꽃과 열매에 대해 형태적 특성을 조사한 결과, 화서의 너비와 암꽃잎의 길이는 품종에 따라 유의적 차이가 있었다. 또한 각 특성에 대한 기여도 확인을 위해 주성분을 확인한 결과, 제3주성분까지의 누적 설명력은 71.0%였고, 화서의 크기, 열매 송이의 크기, 암꽃잎의 크기, 종자의 무게, 종자 수는 높은 상관관계를 보였으며, 이러한 특성들은 품종을 설명하는데 있어 중요도가 높다고 사료된다. 분산분석 결과와 주성분 분석결과에서 화서의 너비, 암꽃잎의 길이 특성이 공통적으로 유의한 결과를 보였으며, 이 특성들은 품종 특성을 설명하는 데 있어 중요 형질이라 판단된다. 유집분석 결과 거리 수준 15를 기준으로 I그룹은 한초 915호, 1020호와 1030호로 가장 근접하였으며, 나머지 930호, 10호는 각각의 그룹으로 구분되었다. 그러나 질적 특성 결과에서 개화기와 결실기 차이가 확연하게 나타남으로 품종 간 구별되는 것을 확인할 수 있었다. 본 연구를 통해 산초나무의 꽃과 열매의 형태적 특성에서 품종 간 유연관계를 확인하였으며, 산초품종 육성을 위한 기초자료로 이용될 수 있을 것으로 사료되며. 향후 다양한 품종에서 유연관계를 설명을 위해 데이터 처리에 대한 기초자료로 이용될 것을 기대한다.
