An experimentation has been carried out in simulated Mediterranean and tropical laboratory conditions aimed to show the Moso bamboo capability of phytoextraction chromium from contaminated soil. Electronic microscopy supported the analyses performed on soil and on the different plant tissues. A preliminary test on the bamboo has been carried out in laboratory evaluating his growth with irrigation in Mediterranean conditions (600 mm/year) and tropical conditions (1.800 mm/year). A test of the bamboo tolerance of was also carried out by measuring his growth with irrigation with a solution of 100 mg Cr/l, reporting not significant damages to the plant tissues. Subsequently chromium phytoextraction was tested highlighting that bamboo removes Cr from soil with a percentage ranging from 43% (600 mm/year) to 47.4% (1.800 mm/year) of the total content in soil. Lastly, the distribution of chromium in the different fragments of the bamboo plants has been performed. It has been shown that approx. 69% of chromium, in Mediterranean conditions, was in the rhizomes and approx. 68% in tropical conditions. A slightly higher tendency to chromium translocation to leaves has been shown in tropical conditions than in Mediterranean conditions.

地中海条件下用毛竹从铬污染土壤中提取植物

已经在模拟的地中海和热带实验室条件下进行了一项实验，旨在展示毛竹从污染土壤中提取铬的能力。电子显微镜支持对土壤和不同植物组织进行的分析。在实验室中对竹子进行了初步测试，评估了其在地中海条件下（600毫米/年）和热带条件下（1.800毫米/年）的灌溉生长情况。还通过用100 mg Cr / l的溶液灌溉测量其生长来进行竹耐性的测试，结果表明对植物组织的损害不大。随后对铬进行了植物提取物测试，结果表明竹子从土壤中去除了Cr，占土壤总含量的43％（600毫米/年）至47.4％（1.800毫米/年）。最后，进行了铬在竹子植物不同片段中的分布。已经表明，大约。在地中海条件下，根茎中含铬量约为69％，其中约5％为铬。热带地区68％。与热带地区相比，热带地区的铬向叶片易位的趋势略高。
