摘要: Seedlings of kudzu were grown at 350, 675, or 1000 ..mu..l/L CO/sub 2/ in controlled-environment chambers. At elevated concentrations, maximum leaf expansion rates approximately 40% greater, leaves fully expanded several days sooner, larger each position, and production increased 12%. Peak starch accumulation was much greater plants concentrations. Total xylem water potentials higher (less negative) full hydration, osmotic decreased (more by enrichment. 2/, trigger pressure twice that 350 2/. Results suggest expansivity may have been due to the The potential for successful seedling establishment be enhanced as atmospheric concentration continues rise, increasing invasiveness.
