Abstract

NaCl causes stress situation in soil which gives outcome like minimized growth owing to variations in whole plant structure. The study was constructed for exploring the morphological behavior of Gazania grown-up under dissimilar salinity grades (25, 50, 75 and 100 mgl-1 of NaCl). The pot based experiment was arranged out in the design (CRD) with 4 repetitions. Observation data to various traits was collected and subjected to analyze using standard statistical procedures. The results showed that salinity has negative impact on morphological characters like Root & shoot dry wt. ratio, Root & shoot fresh wt. ratio, Root dry wt. (g), Root fresh wt. (g), Shoot dry wt. (g), Shoot Fresh Wt. (g), Root length (cm), Shoot length (cm), Size of flower (cm), Number of flowers plant-1,Time of Flower (MET) [Days], Leaf Area (cm2), Number of leaves/plant, Plant height (cm). The study exposed that control treatment (T0) displayed utmost consequences relatively to other altered treatments under saline condition. Salinity revealed the -ive impact on Gazania growth behavior.
