摘要

给土壤种植的植物叶面喷施钼酸盐等必需元素可以恢复其硝酸还原酶的活性。然而，在水培条件下叶面喷施钼酸盐和硝酸盐对植物硝酸还原酶活性的影响尚未得到研究。因此，我们希望研究在水培条件下叶面喷施钼酸盐和硝酸盐对香茅植物叶片硝酸还原酶活性的影响。通过向柠檬香茅植株叶片喷洒硝酸盐和钼酸盐溶液，并用比色法测定硝酸还原酶活性。研究结果表明，施用钼酸盐和 KNO3 溶液可提高香茅植物叶片中硝酸还原酶的活性。重要的是，我们的研究结果表明，在水培条件下，用硝酸盐和钼酸盐进行叶面施肥可以改善香茅植物叶片的氮代谢和碳固定。

Foliar Fertilization with Molybdate and Nitrate Up-Regulated Activity of Nitrate Reductase in Lemon Balm Leaves

The foliar feeding of soil-grown plants with essential elements such as molybdate can restore their Nitrate reductase activity. However, the activity of nitrate reductase under the foliar feeding of plants with molybdate and nitrate in hydroponic conditions has not been investigated. Thus, we wanted to investigate the effect of the foliar feeding of molybdate and nitrate on the nitrate reductase activity in the leaves of lemon balm plants under hydroponic conditions. Nitrate and molybdate solutions were applied by spraying the leaves of lemon balm plants and the nitrate reductase activity was determined by the colorimetric method. The results of our study demonstrated that the application of molybdate and KNO3 solution enhanced the nitrate reductase activity in the leaves of lemon balm plants. Importantly, our results indicate that foliar fertilization with nitrate and molybdate can improve nitrogen metabolism and carbon fixation in the leaves of lemon balm plants under hydroponic conditions.

期刊介绍： Horticulturae (ISSN 2311-7524) is an international, multidisciplinary, peer-reviewed, open access journal focusing on all areas and aspects of temperate to tropical horticulture. It publishes original empirical and theoretical research articles, short communications, reviews, and opinion articles. We intend to encourage scientists to publish and communicate their results concerning all branches of horticulture in a timely manner and in an open venue, after being evaluated by the journal editors and randomly selected independent expert reviewers, so that all articles will never be judged in relation to how much they confirm or criticize the opinions of other researchers.
