Abstract:
Effects of salinity on biomass production, water content, and ion accumulationpattern in
Atriplex amnicola P. G. Wilson, Atriplex calotheca L., Atriplexhortensis
L., Chenopodium album L., Salsola kali L., and Suaeda nudiflora Moq.(all Chenopodiaceae) have been studied. The plants survived and exhibited no
toxicity symptoms up to 6000 mg L
21 NaCl treatment. Ion composition was variablein plants grown under different salinity treatments. Salinity, except in
Suaedanudiflora
where the least biomass was produced in control, affected all other speciesnegatively, and they produced the least biomass at high salinity treatment. Shoot
water content of
Suaeda nudiflora and Chenopodium album increased significantlyin response to salinity. Among all the species examined here, maximum sodium
(Na
þ) accumulation was recorded for Suaeda nudiflora, and it increased with theincreasing salinity. This study concluded that among all the species tested,
Suaedanudiflora
was most suitable plant for bioremediation of salt-contaminated soils.Acknowledgement: Support form DAAD and Humboldt Foundation for this investigation to Professor Dr Neumann and Professor Ashwani Kumar is gratefully acknowledged.
