摘要: Variations of more than 1 percent are observed in the carbon-13 to carbon-12 ratio extracts leaves succulent Kalanchoe blossfeldiana when photoperiod is changed from long short days. This indicates that mechanism carbon fixation switches Calvin (C(3)) pathway Hatch-Slack (C(4)) primary enzymic operation. The variations isotope compositions tentatively explained by a model.
