摘要
以柚为试材,测定了10个品种柚的叶片厚度、上表皮厚度、下表皮厚度、栅栏组织厚度、海绵组织厚度、叶片组织结构紧密度、气孔纵径、气孔横径、气孔大小、气孔密度和气孔相对面积,采用隶属函数分析法进行柚不同品种的抗旱性分析。结果表明:10个品种在各项叶片解剖结构指标上差异极显著。对11个抗旱指标进行了主成分分析和隶属函数分析,10个品种的抗旱性大小排序为:左氏柚>矮文柚>东风早柚>虎蜜柚>脐柚>华蓥山柚>通贤柚>梁平柚>早熟柚>强德勒。
Ten cultivars pummelo were used as test material, the drought resistance indexes of leaf thickness, top epidermis thickness,lower epidermis thickness, thickness of palisade tissue, leaf tissue structure tense ratio(CTR), longitudinal diameter of stoma, horizontal diameter of stoma, stoma density, stoma size and relative area of different cultivars pummelo were measured, by the method of membership function on drought resistance indexes were analyzed. The results showed that differences of each anatomical leaf structure index among the 10 cuhivars were extremely significant. Then the principal component analysis of 10 leaf anatomical structure indexes were calculated. According to the result, an order of drought resistance of the 10 cuhivars was given by using subordinate function values analysis: Zuoshiyou 〉Aiwenyou 〉 Dongfengzaoyou 〉Humiyou 〉 Qiyou 〉 Huayingshanyou 〉 Tongxianyou Liangpingyou〉 Zaoshuyou〉 Chandler Pummelo.
