硫营养对小花南芥(Arabis alpinal Var.parviflora Franch)累积铅锌的影响研究
Effects of Sulfur Application on Growth and Lead and Zinc Accumulation Contents in Arabis alpinal Var parviflora Franch
摘要
Abstract
The effects of sulfur nutrition on growth and Pb/Zn accumulation in hyperaccumulator(Arabis alpinal Var. parviflora Franch) were investigated with pot experiments. The results showed that the shoot biomass of Arabis alpinal Var. parvi flora Franch increased significantly with increase in sulfur contents by 49.5％～118.6％. The root biomass ofArabis alpinal Var. parviflora Franch increased by 114.5％ with 64 mg·kg-1 sulfur treatment. The accumulation content of lead in Arabis alpinal Var. parviflora Franch increased by sulfur. The accumulation contents in shoot and root increased by 1.74～2.92 times and 2.01 ～3.86 times, respectively. The accumulation content of zinc in Arabis alpinal Var. parvi flora Franch increased with 8 mg·kg-1 and 16 mg ·kg-1 sulfur treatments. It was suggested that the growth and Pb/Zn accumulation contents in A rabis alpinal Var. parviflora Franch could be enhanced by sulfur nutrition application.关键词
