Abstract:

通过盆栽培养试验结合差速离心技术,研究了钒(Ⅴ)在芥菜(Brassicajuncea)和小白菜(Brassicachinensis)的叶片、叶柄和根系中的亚细胞分布和积累。研究表明,Ⅴ在芥菜和小白菜不同器官中的含量和分配比例大小依次为:根系>叶片>叶柄,不同蔬菜地下部和地上部积累的Ⅴ含量和分配比例有明显差异,芥菜吸收积累Ⅴ的能力大于小白菜。随着Ⅴ处理浓度的增加,芥菜和小白菜富集系数(BCF)增加,而转运系数(TF)减小,表明蔬菜对Ⅴ有一定的富集能力,两种蔬菜转运Ⅴ的能力降低,其积累的Ⅴ主要富集在植物根部,可减轻过量Ⅴ对可食部分的伤害。Ⅴ在植株各器官的亚细胞分布主要为细胞壁和含核蛋白的细胞可溶性组分,在芥菜和小白菜根系中,两种组分的Ⅴ含量之和占总量的73.4%~78.6%,在叶柄中占总量的74.9%~79.8%,叶片中为86.6%~93.2%,而Ⅴ在细胞核、线粒体和叶绿体两种细胞器中的分配较少,根系为21.4%~26.6%,叶柄为20.1%~25%,叶片为6.8%~13.4%。随着Ⅴ处理浓度的增加,蔬菜根系和叶片中Ⅴ在细胞壁的分配增加,在含核蛋白的细胞可溶性组分的分配减少;在叶柄中Ⅴ在含核蛋白的细胞可溶性组分的分配增加,细胞核和线粒体叶绿体两组分的分配减小。在不同Ⅴ浓度处理下,芥菜较小白菜对Ⅴ有较强的耐性,而细胞壁固持和可溶性组分的液泡区隔化可能是蔬菜耐Ⅴ的主要机制。
