英文摘要 | We investigated endogenous plant hormones and needle growth in Pinus tabulaeformis plants grown in open-top chambers and exposed to ambient or elevated concentrations of carbon dioxide (CO(2)) and/or ozone (O(3)). Exposure to elevated CO(2) for 100 days significantly increased the change in fresh needle weight, indole-3-acetic acid (IAA), isopentenyl-adenosine (iPA), and dihydrozeatin riboside (DHZR) content. Abscisic acid (ABA) content decreased, and no effect was observed on zeatin riboside (ZR) content or changes in needle dry weight. The ratios of IAA/ABA and total cytokinins (CKs)/ABA (ZR + DHZR +iPA/ABA) were increased. Elevated O(3) significantly decreased IAA and ZR, and decreased the ratios of IAA/ABA and CKs/ABA. Ozone treatment increased ABA content but did not change iPA or DHZR content or change fresh or dry needle weights. The combination treatment significantly increased ABA content and the IAA/ABA ratio but decreased the total CKs/ABA ratio and had no effect on CKs or IAA content or change in fresh and dry needle weights. The results indicate that elevated CO(2) ameliorated the effects of elevated O(3) on tree growth. |
