检测芸薹属中几种植物的碳酸酐酶在根、茎、叶中的分布和活性以及叶片净光合速率和锌元素含量的结果表明:碳酸酐酶在甘蓝型油菜的根、茎、叶中均有分布,叶中的碳酸酐酶活性最大,茎中的次之,根中的最小。不同芸薹属植物中碳酸酐酶活性的大小依序为:甘蓝型油菜>白菜型油菜>芜菁>埃塞俄比亚芥。以甘蓝型油菜为例,碳酸酐酶活性的日变化呈双峰曲线,在整个生育期的变化趋势是先上升后下降,抽薹期间的碳酸酐酶活性最高。碳酸酐酶活性与净光合速率以及与锌元素含量之间均呈现显著的正相关。
The results showed that the activity of carbonic anhydrase in roots, stems and leaves and the net photosynthetic rate and the content of zinc in several Brassica plants showed that the activity of carbonic anhydrase in roots, stems and leaves of Brassica napus There are distribution, the leaves of the largest carbonic anhydrase activity, followed by the stem, the smallest root. The order of carbonic anhydrase activity in different Brassica plants is: Brassica napus> Brassica campestris> Turnip> Ethiopian mustard. Taking rapeseed (Brassica napus L.) as an example, the diurnal variation of carbonic anhydrase activity showed a bimodal curve. The trend of the whole growth period was firstly increased and then decreased, while carbonic anhydrase activity was the highest during bolting. Carbonic anhydrase activity showed a significant positive correlation with net photosynthetic rate and zinc content.
