Abstract
⺠In shade light a prairie ecotype of Stellaria longipes shows highly plastic growth. ⺠But, an alpine ecotype of the S. longipes complex gave no growth response to shade light. ⺠Prairie ecotype plants had mainly trans-cytokinins: trans-zeatin and dihydrozeatin. ⺠Alpine ecotype plants had mainly cis-cytokinins - which are of low biological activity. ⺠Growth response differences between ecotypes appears linked to cytokinin profiles.
