| Summary: | Some Pteris vittata genotypes, collected from different locations of China, were planted in pots to evaluate their ability in As tolerance and accumulation. Results showed that there were dramatic difference in plant height, biomass and frond number. The plant height ranged from 29.6 to 68.2 cm, frond number from 18.0 to 60.0 per plant, shoot fresh weight from 150 to 540 g per plant and root fresh weight from 20.3 to 94.9 g per plant. The distinct difference among the genotypes was also found in shoot and root As accumulation, ranging from 643.10 to 3009.03 mg·kg<sup>-1</sup> and from 26.34 to 112.38 mg·kg<sup>-1</sup>, respectively. It was found that accession C108 had the highest As accumulation in shoot, being significantly higher than all other accessions. There was a significant difference among the accessions of Pteris vittata in both transporting factor (TF) and biological factor (BF). There was a positive association between As accumulation and some growth characters, including plant height, frond and bud numbers, and shoot fresh weight. |
