Abstract

Arbuscular mycorrhizal fungi (AMF) support plant development, however, symbiosis depends on species of both symbionts. This study aimed to evaluate the interaction between rootstock citrus inoculated with species of arbuscular mycorrhizal fungi. Three rootstocks citrange ‘Fepagro C37 Reck’ [ Poncirus trifoliata (L.) Raf. x Citrus sinensis (L.) Osbeck.], ‘Hong-Kong’ kumquat ( Fortunella hindsii Swingle) and ‘Trifoliata’ ( Poncirus trifoliate ) were tested, inoculated with two species of AMF ( Glomus etunicatum W.N. Becker & Gerd.and Acaulospora sp. ) and a treatment not inoculated. We evaluated the height (cm), stem diameter (mm), leaf area (cm² / plant), leaf number, fresh and dry root and shoot weight (g), the level of reserves in tissues and the colonization of AMF in the roots. The species G. etunicatum and Acaulospora sp . colonized the roots of rootstocks, but they were only eff ective for ‘Fepagro C37 Reck’. Poncirus trifoliata had the highest vigor in the absence of AMF.

柑橘砧木与丛枝菌根真菌的相互作用

丛枝菌根真菌(AMF)支持植物发育，但其共生关系取决于两种共生体的种类。本研究旨在评价柑橘砧木接种丛枝菌根真菌后的相互作用。三种砧木柑桔‘Fepagro C37 Reck’[Poncirus trifoliata (L.)]英国皇家空军。x柑桔(L.)等。用两种AMF (Glomus etunicatum W.N. Becker & Gerd)接种，对“香港”金桔(Fortunella hindsii Swingle)和“三叶草”(Poncirus trifoliate)进行了试验。和Acaulospora sp)和未接种处理。我们评估了高(cm)，茎粗(mm)，叶面积(cm²/株)，叶数，鲜干根重(g)，组织储量水平和AMF在根中的定植。本种为棘球绦虫和棘球绦虫。在砧木的根部定植，但它们只对Fepagro C37 Reck有效。在没有AMF的情况下，三叶松的活力最高。

期刊介绍： The Iheringia, Série Botânica is a publication edited by the Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, since 1958. The name Iheringia is actually a tribute to Hermann von Ihering (a German researcher who became a Brazilian citizen) and his important studies in the Natural Sciences.The journal has the mission of publishing articles, reviews and original scientific notes that cover diverse areas in Botany, and may be written in Portuguese, Spanish and English. The journal is widely available in both international and national scientific community. The issues are published and distributed twice a year to 118 national institutions and 152 international institutions. The distribution is either free of charge or by exchange.
