Similarly, radical length was also decreased with increased
salinity (Figure 2). Radicle length was more
suppressed than plumule by salinity at each specific salt
concentration level. At all salinity level variety, Pokkali,
MR232 and MR 211 produced significantly higher radical
length compared to other varieties and BR29 produced
lowest radical length. The gradual decrease in root length
with the increase in salinity as observed might be due to
more inhibitory effect of NaCl salt to root growth compared
to that of shoot growth (Rahman et al., 2001).
