Effect of salt stress on morpho-physiology, vegetative growth and yield of rice


M.A. Hakim and Abdul Shukor Juraimi and M.M. Hanafi and E. Ali and Mohd. Razi Ismail and Ahmed Selamat and S.M. Rezaul Karim (2014) Effect of salt stress on morpho-physiology, vegetative growth and yield of rice. Journal of Environmental Biology, 35. pp. 317-326. ISSN 0254-8704


Selection of salt tolerant rice varieties has a huge impact on global food supply chain. Five Malays
ian rice
Oryza sativa
L.) varieties, MR33, MR52, MR211, MR219 and MR232 were tested in pot experiment under
different salinity levels for their response in term of vegetative growth, physiological activities,
of yield components and grain yield. Rice varieties, BRRI dhan29 and IR20 were used as a salt-sensit
control and Pokkali was used as a salt-tolerant control. Three different salinity levels viz. 4, 8,
and 12 dS m
were used in a randomized complete block design with four replications under glass house conditions
. Two
Malaysia varieties, MR211 and MR232 performed better in terms of vegetative growth (plant height, le
area plant , number of tillers plant , dry matter accumulation plant ), photosynthetic rate, transpirat
ion rate,
yield components, grain yield and injury symptoms. While, MR33, MR52 and MR219 verities were able to
withstand salinity stress over salt-sensitive control, BRRI dhan29 and IR20
