柑与桔应否分别具有种的地位,取决于野生柑桔资源的研究结果。根据莽山野柑、莽山野桔、道县野桔,通道野桔和有关地方品种的形态,孢粉特征的模糊聚类分析,可将柑和桔区分为性状相似性的相关系数仅0.2303的两类元,莽山野柑与莽山野桔血清学关系的异源沉淀带之和与同源沉淀带之和的比率为40%,酯酶同工酶谱中柑类具有Est-12特征带,野柑和3个野桔的核型分别为2n=2x=18=18m和2n=2x=18=16m=16m+2Sm。以此为据,可以认为柑与桔分别具有种的地位。
Whether or not citrus and orange should have their own status depends on the findings of wild citrus resources. According to the fuzzy clustering analysis of the morphological and sporopollen characteristics of Wild Mangosteen, Mangshan Wild Orange, Daoxian Wild Orange, Channel Wild Orange and other local landraces, the correlation coefficient of similarity between the wild and wild oranges was only 0.2303 The ratio of the sum of heterozygous sediments of the genus Metarhizium, Mangosteen and Mangosteen orange serogroups to the sum of the same sedimentation belts was 40%. The esterase isozymes had the Est-12 characteristic bands The karyotypes of mandarin and three wild berries were 2n = 2x = 18 = 18m and 2n = 2x = 18 = 16m = 16m + 2Sm, respectively. Based on this, we can think that citrus and orange have their own status.
