摘要: ABSTRACT – (Comparative anatomy study of stem bark yellow strawberry-guava and red strawberry-guava, Psidium cattleianum Sabine, Myrtaceae). , known as belongs to the Myrtaceaefamily. This family has many taxonomy problems, for this reason, is considered one most complicated identification theirspecies. With intention clarify these difficulties, some alternative studies are being developed, such bark, toolthat contributes understanding taxonomic problems; however, it a tool currently few explored. In present study, thestructure was analyzed compared, in order verify thehypothesis two taxons P. . For way samples three individuals each morphotypes had been collected andprocessed agreement procedure indicated structural analyzes. The differences between can be observed inperiderm, arrangement parenchymatics cells and, general or ganization collapsed phloem. results gottenin research showed that
