现有的生理学证据表明，E. Grandis幼苗涉及茎插穗的生根能力降低与形成插穗基部的组织中生根抑制剂水平增加之间的直接和定量关联。如通过生物测定所检测的，这种抑制剂仅存在于成体组织中，其很少从茎插条形成根。在所有供试的桉树种的易生根的幼苗茎中不存在，但在例外的桉树种的易生根的成年组织中也不存在。deglupta。结果表明，E. deglupta在水中非常容易生根的特性为监测其他桉树物种中抑制剂的存在提供了适当的生物测定。
The available physiological evidence suggests that ontogenetic ageing of E. Grandis seedlings involves a direct and quantitative association between decreased rooting ability of stem cuttings and increased levels of a rooting inhibitor in the tissue forming the base of the cutting. As detected by bioassay, this inhibitor is present only in adult tissue, which very rarely forms roots from stem cuttings. It is absent in easily rooted seedling stems of all Eucalyptus species tested, but it is also absent in the easily rooted adult tissue of the exceptional species E. deglupta. The ability of seedling cuttings of E. deglupta to root very easily in water provides an appropriate bioassay for monitoring the presence of inhibitor in other Eucalyptus species.
