Comparative arsenic tolerance and accumulation potential between wild Tagetes patula and Tagetes minuta
Arsenic (As) is a bioactive metalloid that is highly toxic to humans, animals, and plants. Environmental contamination of As especially in groundwater increases due to natural and anthropogenic activities. The present study was performed to evaluate the potential of wild Tagetes species for the...

| description | Arsenic (As) is a bioactive metalloid that is highly toxic to humans, animals, and plants. Environmental contamination
of As especially in groundwater increases due to natural and anthropogenic activities. The present study was performed to
evaluate the potential of wild Tagetes species for the phytoremediation of As contaminated soil/water. This comparative
research aims to analyze As accumulation and tolerance in two wild species of Tagetes, T. minuta and T. patula. The
20 days old seedlings were grown hydroponically and exposed to the different concentrations of As, 0, 50, 150, and
300 µM As2
O3
for 1-, 4- and 7- days intervals.Effect of As stress was measured on the rate of seed germination, growth
parameters like fresh and dry biomass weight, root/shoot length, chlorophyll contents and As contents in root and
shoot in both Tagetes species. Increasing concentration of As restricts the growth activity of T. minuta with toxicity
symptoms on leaves such as chlorosis. Accumulation of As in the shoot was significantly (p ≤ 0.01) high (634 µg g-1 DW)
in T. patula as compared to T. minuta (397 µg g-1 DW) at 300 µM As2
O3
. Both Tagetes species exhibited high variation
for As tolerance parameters as well as for As accumulation patterns. Comparatively good tolerance and accumulation of
As in T. patula suggests that this species could be used in phytoextraction and re-vegetation in As contaminated sites. |
