褪黑激素作为一种在进化上高度保守的分子，在植物中表现出异常多样的作用。以“浙粉701号”番茄为试材，研究长期施用外源褪黑激素对番茄果实品质和产量的影响。种子发芽前用褪黑激素浸泡的植株产量高，抗坏血酸、番茄红素和Ca元素含量高，N、Mg、Cu、Zn、Fe、Mn元素含量低。相比之下，植物灌溉每周补充褪黑激素的营养液表现出显着改善其可溶性固形物，抗坏血酸，番茄红素，柠檬酸和P元素的含量相比，对照组植物只收到一个标准的解决方案。这些结果首次为褪黑激素在提高番茄果实产量和品质方面的作用提供了证据。(C)© 2016 Elsevier B.V.版权所有。
As a highly conserved molecule evolutionarily,melatonin displays an exceptional multiplicity of actions in plants. Our study objective was to analyze how long-term applications of exogenous melatonin influence the quality and yield of fruit from 'ZheFen No. 701' tomato (Solanum lycopersicum). Plants that grew from seeds that had been soaked with melatonin prior to germination had much higher yields as well as more ascorbic acid, lycopene and the content of Ca element, while the content of N, Mg, Cu, Zn, Fe, and Mn element decrease. By contrast, plants irrigated weekly with melatonin-supplemented nutrient solutions showed significant improvements in their contents of soluble solids, ascorbic acid, lycopene, citric acid, and P element when compared with control plants that received only a standard solution. These results are the first to provide evidence for the role that melatonin has in increasing both fruit yield and quality in tomato. (C) 2016 Elsevier B.V. All rights reserved.
