- 摘要:
- 以12个引自美国的藤本月季品种为试材,测定了不同品种植株的超氧化物歧化酶(SOD)活性、过氧化物酶(POD)活性、叶绿素a(Chl-a)含量、叶绿素b (Chl-b)含量、叶绿素总量(T-chl)、可溶性糖含量和可溶性蛋白质含量等7个与适生性相关的生理指标。采用主成分分析、隶属函数分析以及聚类分析法对相关变量进行分析,对引种藤本月季原株适生性进行评价和筛选。结果表明:利用主成分分析将7个相关指标可转化为3个主成分,累计贡献率达到82.626%;并通过聚类分析将12个供试藤本月季品种的适生性分为适生性强、适生性中等和适生性较弱3个等级。初步筛选出‘Super Excelsa’‘Eden Rose′88’‘Handel’‘Alchymist ’‘Aloha’ 等5个适生性较好的品种,可为藤本月季引种和园林应用提供借鉴。
- Abstract:
- Twelve climbing rose varieties from the United States were used as materials.Seven physiological indexes related to the adaptability were measured,including SOD activity,POD activity,chlorophyll a (Chl-a),chlorophyll b (Chl-b),total chlorophyll (T-chl),soluble sugar content and soluble protein content.The adaptability of the introduction of the original plant of climbing rose varieties were evaluated and selected by principal components analysis,membership function analysis and clustering analysis.The results indicated that principal component analysis was used to transform the seven related indexes into three principal components,and the cumulative contribution rate was 82.626%;the results of cluster analysis showed that the adaptability of 12 varieties of climbing roses were divided into three levels,strong adaptability,medium adaptability and weak adaptability.‘Super Excelsa’‘Eden Rose′88 ’‘Handel’‘Alchymist ’‘Aloha’ were screened out,which provided a reference for the introduction and application of climbing rose.
