(13)C/(12)C ratios have been determined for plant tissue from 104 species representing 60 families. Higher plants fall into two categories, those with low delta(PDBI) (13)C values (-24 to -34 per thousand) and those with high delta (13)C values (-6 to -19 per thousand). Algae have delta (13)C values of -12 to -23 per thousand. Photosynthetic fractionation leading to such values is discussed.
已为代表 60 个科的 104 种植物组织确定了 (13)C/(12)C 比值。高等植物分为两类,一类具有较低的 δ(PDBI)(13)C 值(-24 至-34/千),另一类具有较高的 δ(13)C 值(-6 至-19/千)。藻类的 δ(13)C 值为-12 至-23/千。讨论了导致这种值的光合作用分馏作用。
