Abstract

Neutral nanoparticles (NPs) of iron, zinc, copper or their compositions were introduced into nutrient Murashige-Skoog (MS) medium instead of traditional metal salts with/without chitosan supplements to obtain healthy and crop productive plants. Metal NPs concentrations were: Fe NPs (0.06, 0.3, 3.0); Zn NPs (0.016, 0.08, 0.4); Cu NPs (0.004, 0.0008, 0.00016) (mg L-1). Pepper (Capsicum annuum) cultivar LJ-King was grown on modified media in aseptic conditions. After 45 days, root and stem length, root activity, green mass gain and chlorophyll content in leaves were measured. Pepper plants grown on media with metal NPs showed increased root length and activity (for Fe, Zn, Cu NPs and their composition) and chlorophyll content in leaves (for NPs Fe and Cu). However, addition of Chitosan modified the effects. Monitoring of pepper grown on MS with NPs composition (Fe: Zn: Cu as 3.0:1.0:0.004 mg L-1) with electron microscope demonstrated no NPs accumulation in roots, sprouts and leaves.

辣椒植物对营养介质中金属纳米粒子和壳聚糖的响应

将中性铁、锌、铜纳米颗粒(NPs)或其组合物添加到营养介质Murashige-Skoog (MS)中，以取代传统的金属盐，在添加/不添加壳聚糖的情况下获得健康的作物高产植株。金属NPs浓度分别为:Fe NPs(0.06、0.3、3.0);Zn NPs (0.016, 0.08, 0.4);Cu NPs (0.004, 0.0008, 0.00016) (mg L-1)。对辣椒品种LJ-King在改良培养基上进行了无菌培养。45 d后，测定根、茎长、根系活性、叶片绿质量增益和叶绿素含量。在金属NPs培养基上生长的辣椒根系长度、活性(对铁、锌、铜NPs及其组成)和叶片叶绿素含量(对铁和铜NPs)均有所增加。然而，壳聚糖的加入改变了这种效果。在铁:锌:铜为3.0:1.0:0.004 mg L-1的培养基上对辣椒进行电镜观察，发现辣椒根、芽、叶均无NPs积累。
