3.1.2.6 Statistical Analysis
All the data presented in this study are mean of three replications. Analysis of
variance (ANOVA) was performed by using a statistical package, Statistix 8.1.
Significant differences among treatments were considered at the P ≤ 0.05 levels.
3.1.3. Results
There was very significant difference among linseed genotypes in terms of growth
and ionic parameters. The interactions between salinity levels and genotypes were also
significant (P<0.05) for seedling growth [shoot dry weight (SDW), root dry weight
(RDW), root length (RL) and shoot: root ratio (S/R)] and ionic parameters (Na
+
, K
+
and Na
+
/K
+
) measured 30 days after salinity stress, indicates that there was variable
response of genotypes to salinity from low to high levels (Table 3.1.1). The response of
linseed genotypes in terms of their growth and ionic parameters at control, 100 and 200
mM NaCl are presented and discussed here.
