Does soil nitrogen influence growth, water transport and survival of snow gum (Eucalyptus pauciflora Sieber ex Sprengel.) under CO2 enrichment?
Eucalyptus pauciflora Sieber ex Sprengel. (snow gum) was grown under ambient (370 L-1) and elevated (700 L-1) atmospheric CO2 in open-top chambers (OTCs) in the field and temperature- controlled glasshouses. Nitrogen applications to the soil ranged from 0.1 to 2.75 g N per plant. Trees in the field at high N levels grew rapidly during summer, particularly in CO2-enriched atmosphere, but suffered high mortality during summer heatwaves. Generally, wider and more numerous secondary xylem vessels...[Show more]
