不同供钾水平对金盏花幼苗生长特性和酶活性的影响
Effects of Different Potassium Application Rates on Growth Charactre istics and Enzymatic Activity of Calendula officinalis Seedlings
摘要
Abstract
The effects of different potassium application rates on the growth characteristics and enzymatic activity of seedlings of different Calendula officinalis varieties were studied through pot tests.The results showed that:when the application rate of po-tassium increased, the plant height, stem fresh weight, stem dry weight, leaf fresh weight, and leaf dry weight of different calen-dula varieties all increased first and then decreased, and they were relatively high in the treatment of 150 kg/hm2 potassium sup-ply;along with the increase in the application rate of potassium, the activity of POD and CAT revealed the trend of rising first and then declining, while the activity of SOD reduced first and then increased;the MDA content decreased, and the contents of solu-ble protein and proline increased with the increase in the application rate of potassium .关键词
