Seedlings of Ecalyptus grandis W. Hill ex Maiden were found to be more resistant to waterlogging than those of Eucalyptus robusta Sm. and seedlings of both species were more resistant than those of Eucalyptus saligna Sm. Resistance depended on the stress avoidance mechanism of adventitious root formation. The ethylene-releasing growth substance 2-chloroethylphosphonic acid (ethephon) applied to non-flooded plants was used as a tool to study the role of ethylene in the response of plants to waterlogging. Plant height and total dry weight decreased linearly with plant ethylene content. There was no difference between the species in their response to ethephon.
人们发现，巨桉（Ecalyptus grandis W. Hill ex Maiden）的幼苗比粗皮桉（Eucalyptus robusta Sm.）的幼苗更耐涝，并且这两个物种的幼苗都比柳桉（Eucalyptus saligna Sm.）的幼苗更耐涝。抗性取决于不定根形成的胁迫规避机制。将释放乙烯的生长物质2-氯乙基膦酸（乙烯利）施用于未受淹的植物，以此作为研究乙烯在植物对涝渍响应中作用的一种手段。株高和总干重随植物乙烯含量呈线性下降。各物种对乙烯利的反应没有差异。
