HIGHLIGHTS

  • Pb tolerance and accumulation by fibrous plants were conducted at early growing stage.
  • Jute, kenaf and mesta seedlings were survived up to 160 mg Pb L-1 in growing media.
  • Bioaccumulation factor (BCF) indicated all varieties were Pb accumulator.
  • Translocation factor (TF) showed slowly translocation of Pb from root to shoot.
  • Maximum 346 and 3952 mg Pb kg-1 were recorded in shoot and root, respectively.

ABSTRACT

Lead (Pb) is one of the environmentally hazardous toxic heavy metals. Some plants have the ability to tolerate and absorb this toxic metal. The current study was conducted to evaluate Pb tolerance and absorption capacity of jute (Corchorus capsularis L. var. BJC-7370 and CVE-3), kenaf (Hibiscus cannabinus L. var. HC-95 and HC-3) and mesta (Hibiscus sabdariffa L. var. Samu-93). Seedlings of these varieties were grown in hydroponic nutrient solution having four levels of Pb, viz 0, 80, 120 and 160 mg L-1 with four replications. Results showed that the seedlings of jute, kenaf and mesta were highly potential to tolerate Pb toxicity. Lead had no significant effects on the survibility of jute, kenaf and mesta seedlings. All the seedlings were normally survived up to 160 mg L-1 Pb contaminated hydroponic solution. Root and shoot length and dry biomass were decreased with the increasing levels of Pb. Bio-concentration factor values indicated that all the varieties were Pb accumulator. Translocation factor indicated that Pb is slowly translocated from root to shoot in all varieties and the rate of translocation is increased with the increasing concentration of Pb. Accumulations of Pb in root were higher than shoot. Highest Pb contents in shoot (345.82 mg Pb kg-1) and root (3951.50 mg Pb kg-1) were detected from mesta (var. Samu-93) than other varieties. On the other hand, the maximum (8.75 mg Pb pot-1) Pb absorption was calculated from the variety of jute CVE-3. At initial stage of growing, Pb absorption potentiality of the varieties in the order of jute CVE-3 > jute BJC-7370 > kenaf HC-3 > kenaf HC-95 > mesta Samu-93. The findings of this study can be used in phytoremediation of Pb-contaminated environment.
