“…In our experiment, root growth was relatively more sensitive to salt than the shoot in water culture. This is in confirmatory with the findings of Asana and Kale (1965) and Ansari et al (1980) who reported that NaCI and CaCl 2 salts are more inhibitory to root growth compared to that of shoot growth of wheat plants. In soil culture, the suppressing effect of NaCI on shoot fresh weight was more pronounced than on root fresh weight.…”

“…Munns and Termaat (1986) reported that at low salinity levels root growth may not decrease at all; it can even increase resulting in an increase in root:shoot length. The gradual decrease in root:shoot length with the increase in salinity as observed in our experiment might be due to more inhibitory effect of NaCI salt to root growth compared to that of shoot growth (Ansari et al, 1980;Asana and Kale, 1965). In our experiment, the increase in root:shoot fresh and dry weights with the increase in salinity is in good agreement with the earlier reports (Bernstein, 1975;Nejad and Najafi, 1990;Munns and Termaat, 1986;Nieman et al, 1988).…”

Nipponbare (typical japonica type), Gorishita and Pangri (indica type; cultivated in the southern districts of Bangladesh) were compared with emphasis on seed germination and early seedling growth characters. Seeds were placed for germination and the seedlings were allowed to grow for 7 days at 0, 0.01, 0.03, 0.06 and 0.1% NaCI concentrations in water culture and for 14 days at 0, 0.1, 0.3, 1.0 and 3.0% NaCI concentrations in soil culture. Salinities up to 0.3% delayed germination but did not reduce final germination percentage; it was reduced significantly at $1.0% NaCI. Rice cultivars at the stage of seed germination were more tolerant to salinity than at the early seedling stage. Lower levels of salinity were not much inhibitory to the length, fresh and dry weights, reduction in moisture content of root and shoot but under higher levels of salinity, almost all these parameters were significantly affected in all cultivars. Among the cultivars, Nipponbare performed well by producing highest root length, fresh and dry weights of root and shoot, total dry matter and with a relatively high root:shoot length, fresh and dry weight.
