abstract：:Cytokinins promote expansion of cotyledons detached from seedlings of more than a dozen species. The zeatin-enhanced expansion of cucumber (Cucumis sativus L. cv Marketer) cotyledons was investigated. In addition, whether acid secretion is involved in wall loosening accompanying such accelerated growth was evaluated. ...
