摘 要 :对7种园林草坪植物根段染色结果表明:VAM侵染植物根段后可分别形成泡囊状、菌丝状、丛枝状、圈状、棒状吸器;VAM对根尖的侵染率差异以分生区最显著,并可诱导形成根原基;VAM可侵染根冠。
Abstract:The result of root dying to 7 lawn plants indicates there are 5 kinds of haustoriums intra-cell.The most high infest rate of VAM to root tip is the meiosis zone,VAM can induce root primordium here, VAM also can infect the root cap.
