Abstract

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.
