EFFECT OF SALINITY ON GERMINATION AND SEEDLING GROWTH OF WHEAT GENOTYPES (Pages : 1 - 8)

E. SULTANA, M.A. HASAN, S. SIKDER, M.S. RANA AND F. ALAM

To investigate the influence of salinity on germination characters and seedling growth thirty wheat genotypes were tested in petridish under control and saline (15 dS m-1) condition at Crop Physiology and Ecology Laboratory, Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period from September to October 2013. Speed of germination as expressed by rate of germination and germination vigor index of all wheat genotypes was reduced due to salinity. Shoot length and root length and seedling dry weight of 10 days old seedlings were found to be affected due to salinity. But the magnitude of reduction of these parameters due to salinity was not similar for all wheat genotypes. Salt tolerance index (STI) of thirty wheat genotypes based on shoot length, root length and seedling dry weight at salt stress indicated a wide difference in stress tolerance among the wheat genotypes. Considering shoot and root length, seedling dry weight and early seedling growth Sourav, Shatabdi, Sufi, BARI Gom 25, BARI Gom 27 and BAW 1186 were found as more salt tolerant and BAW 1199 was found as salt sensitive wheat genotypes.Download
