Polyploids and their structural and physiological characteristics relative to water deficit in Betula papyrifera (Betulaceae)

The morphology and leaf anatomy, water relations, gas exchange, and growth characteristics of Betula papyrifera seedlings grown in a greenhouse representing three ploidy levels (diploids, pentaploids, and hexaploids) have been compared in an effort to understand the role of polyploidy in habitat dif...
