不同类型烟草光合特性的比较研究
Acta Agriculturae Universitatis Jiangxiensis (Natural Sciences Edition)(2014)
Abstract
以烤烟、晒烟、白肋烟3个不同类型的6个烟草品种为试验材料,在相同条件下,对大田生育期烟草光合特性进行了研究。结果表明:大田期晒烟品种的生育期最短,烤烟次之,白肋烟最长;在团棵期和旺长期净光合速率由大到小依次为:晒烟、白肋烟、烤烟,现蕾期和成熟期净光合速率由大到小依次为:白肋烟、烤烟、晒烟;胞间CO 2浓度分别与净光合速率、气孔导度、蒸腾速率之间呈极显著负相关,净光合速率分别与气孔导度、蒸腾速率之间呈极显著正相关,气孔导度与蒸腾速率之间呈极显著正相关。
