摘要
就钾营养对番红花水分关系影响的差异进行了比较研究。结果表明 :低钾水平 (1mg/L)情况下 ,番红花叶片气孔开度小 ,频度低 ,因而气孔导度小 ,蒸腾强度低。低钾处理的番红花叶束缚水相对含量低 ,水势低 。
A study of the effects of K nutrition on water relation in saffron crocus (Crocus sativus L.) plants showed that low K + treatment (1 mg/L) resulted in lower leaf stomatal frequency and smaller aperture, thus leading to lower stomatal conductance and transpiration intensity. Bound water content and potential were low and proline content was high in the leaf in low K + treatment.
