Description Bamboos are potential species for reclamation of saline soils and
water. In this study, the performances of three bamboo species,
namely Dendrocalamus strictus (S1), Dendrocalamus longispathus
(S2) and Bambusa bambos (S3), were investigated for salinity
stress tolerance. After 14 days of treatment with 100 mM NaCl,
reduction in shoot length was 66%, 100%, 77%, root length was
77%, 100%, 57%, number of leaves was 50%, 100%, 73% and
fresh weight was 30%, 72%, 14% in S1, S2 and S3 species,
respectively. Relative water content (RWC) in S1 and S3 species
was 1.26 and 1.07 folds higher in 50 mM NaCl in comparison to
control. In S2 species, total chlorophyll, chlorophylla and
chlorophyllb degradation were the highest (40.4%, 42.7%, 16.32%,
respectively) in comparison to S3 (18.18%, 23%, 16.4%) and S1
(23.5%, 25%, 19.17%) species. In S3 and S1 species, the Chla/Chlb
ratio was maintained showing stabilisation of the net
photosynthetic rate. Proline played a more important role than
glycine betaine for salt tolerance of these bamboo species. On
account of vegetative growth, proline accumulation and RWC, it is
inferred that S1 and S3 species are salt tolerant while S2 is a
sensitive species.
