大气CO2浓度倍增对宁夏枸杞生长的影响
Effect of Elevated CO2 Concentration on Growth in Lycium barbarum
摘要
Abstract
To study the effects of elevated CO2 concentration( [ CO2 ] ) on growth and fruit active components in Lycium barbarum, the seedlings of L. Barbarum were exposed to either ambient [ CO2 ] [ ( 350 ± 20 ) μmol ? Mol-1 ] or elevated [ CO2 ] [ (700 ± 20) U/inol? Mol-1 ] in open top chambers for four months, and the shoot length, shoot diameter, seedling height, seedling root-collar diameter, and the content of polysaccharide, taurine, flavonoids, carotenoid in the fruits were tested. The result showed that elevated [ CO2 ] increased the growth rate of seedling root-collar diameter, seedling height, and shoot at early growth stage. The flowering and fruiting date of L. Barbarum grown under elevated [ CO2 ] was earlier than that of the control group, and the content of active components such as flavonoids and carotenoid in the fruits were lower than that of the control group, of which the contents of flavonoids, carotenoid were reduced by 22. 1% and 30. 8% , respectively, indicating that elevated CO2 concentration affected the fruit quality of L. Barbarum.关键词
