摘要

在南部非洲国家,由于其对消除饥饿、粮食不安全和营养不良的重大贡献,本地叶菜的生产通常在家庭菜园和/或商业层面进行。黑茄(Solanum nigrum L.)是非洲叶菜(ALV)之一,因其药理和营养价值而受到高度认可。一些研究表明,ALVs可以在露天或温室中栽培,但关于农艺参数和矿物成分变化的资料很少。本研究的目的是比较露天栽培和温室栽培下龙葵的生理参数和矿物质组成。研究结果表明,露天条件下的叶面积和叶绿素含量较高,而温室条件下的株高和叶数较高。在露天种植系统中,镁、铜、锰、铁、锌和铝等矿物质元素含量明显较高,而温室栽培系统中硫和硼含量较高。值得注意的是,钙、磷、钾和钠在露天和温室体系中没有显著差异。此外,据报道,露天田的总氮含量很高,但两种种植制度的水分和灰分含量没有显著差异。综上所述,露天栽培的龙葵叶片叶绿素含量、叶面积和微量元素含量均高于温室栽培,而两种栽培方式的宏观矿物质含量差异不显著。

Response of Black Nightshade to Different Cropping Systems and the Effect on Physiological Parameters and Mineral Composition
In southern African countries, production of indigenous leafy vegetables is commonly practiced at home garden and/or commercial level due to their significant contribution toward eradication of hunger, food insecurity, and malnutrition. Black nightshade (Solanum nigrum L.) is among African leafy vegetable (ALV) highly recognised for its pharmacological and nutritive benefits. Several research have shown that ALVs can be cultivated in the open field or greenhouses, however, little information is available on the changes of the agronomical parameters and mineral composition. The aim of the study was to compare the physiological parameters and mineral composition of nightshade grown in the open field vs. greenhouse cropping systems. The results of the study revealed high-leaf area and relative chlorophyll content in the open field conditions while plant height and the number of leaves were reportedly higher under the greenhouse system. Minerals elements such as magnesium, copper, manganese, iron, zinc, and aluminium were significantly higher in the open field cropping system, while greenhouse cultivation recorded higher sulphur and boron. Notably, no significant amount was observed in calcium, phosphorus, potassium, and sodium between open field and greenhouse system. Furthermore, a significant amount of total nitrogen was reported in the open field, however, no significant difference was observed in moisture and ash content for both cropping systems. In conclusion, black nightshade cultivated in open field provided higher leaf chlorophyll, leaf area, and trace elements compared to greenhouse cultivation while macro minerals concentration had no significant difference in both cropping systems.
