In succulent and non–succulent halophytic plants, five halophytic plants were analyzed for the experimental works. Plant distinguished into three parts leaves, stems and roots.
3.1 Accumulation of elements in succulent plants.
3.1.1. Salicornia brachiata
S. brachiata, a succulent perennial halophytic plant species showed electrical conductivity 5.95 (mS/cm) of soil supporting the species, it also reflected that, EC of the phylloclade, 5.56 (mS/cm) was marginally near to the habitat of plant. The EC of stem and root were noted to be 0.85 and 0.92 mS/cm respectively. The elemental composition in the soil was ranging between 0.19 to 8.47 (meq.g-100). The highest accumulation of (6.16 meq.g-1) was noted for Na+ in the phylloclade of S. brachiata, whereas K+ 0.14 meq.g-1 was observed in stem and roots of this succulent halophytic species. The concentration of these mineral ions followed a sequence of the accumulation ratios in phylloclade are, Na+> Cl->Mg+2> Ca+2> K+, in stem and root it is, Na+> Mg+2> Cl-> Ca+2> K+. S. brachiata accumulate a high amount of salt in phylloclade compare to rest of plants (Table 1).
3.1.2. Suaeda nudiflora
S. nudiflora plant growing under less saline soil compare to the other succulent halophytes. The EC value of soil is 1.30 (mS/cm), generally the habitat of this plant has low salt concentration. The element concentration in soil of this plant between 0.06 to 2.62 (meq.g-100). Leaves has high EC value, 5.29 (mS/cm), whereas in stem and root portion EC value is 1.34 and 0.94 (mS/cm) respectively. Highest accumulated element was Na+ 3.87 (meq.g-1) in the part leaves, where as K+ in low amount (0.15 meq.g-1) in roots. The storage of elements in leaves is followed this high to low value, Na+> Cl-> Mg+2> Ca+2> K+, in stem it is, Na+> Mg+2> Cl-> Ca+2> K+, where in root, only changing a Mg ions, Mg+2> Na+> Ca+2> Cl-> K+ (Table 2).
3.1.3. Suaeda fruticosa
S. fruticosa was the second highest salt accumulator plant in current research. EC value of soil was 4.02 (mS/cm), whereas other elements ranging between low to high concentration 0.19 to 4.94 (meq.g-100). Higher accumulated element was Na+ which is 4.37 (meq.g-1) and lowest was K+ 0.14 (meq.g-1). The mineral accumulation in leaves high to low amount, Na+>Cl-> Mg+2>Ca+2>K+, in stem it was, Na+>Mg+2>Ca+2>Cl->K+, when root has, Mg+2> Na+> Cl-> Ca+2> K+(Table 3).
3.2 Accumulation of elements in non-succulent plants
3.2.1. Aeluropus lagopoides
In the current research non-succulent halophytic grass plant A. lagopoides showed high salt tolerance. The EC value of soil was (4.89 mS/cm), other elements ranging between higher to lower 5.86 to 0.08 (meq.g-100), respectively. Here also a high element accumulator part was leaves same as succulent halophytic plants. EC value of leaves was lowest compare to succulent plant which was 1.81 (mS/cm), Na+ was in higher value 1.47 (meq.g-1), when K+ in lowest amount was (0.10 meq.g-1). Major element composition elements-wise, were, Na+ > Cl-> Mg+2> Ca+2> K+, these ratios followed by leaves. The amount of elements in stem was, Na+> Mg+2>Ca+2>Cl->K+, and in roots was, Na+>Mg+2>Cl->Ca+2>K+. Most of the elements in a high amount in leaves, but in stem the Mg+2 with a high amount 0.93 (meq.g-1) when root high with concentration of Ca+2 0.59 (meq. g-1) (Table 4).
3.2.2. Urochondra setulosa
Comparatively, U.setulosa was accumulates low elements than A.lagopoides, but interestingly it growing under a high saline environment than A.lagopoides, the soil of this plant has high value of Na+, Cl-, was 6.32 and 6.77 (meq.g-100) respectively. EC of soil was 5.88 (mS/cm), when other element concentration wise high to low ranged was, 6.77 to 0.12(meq.g-100). The value of EC highest in leaves, 1.66 (mS/cm), elements concentration ranging from high 1.19 (meq.g-1), to low 0.06 (meq.g-1). The ratios of accumulated elements in leaves, Na+>Mg+2>Cl-> Ca+2> K+, whereas in stems, Mg+2>Na+>Ca+2>Cl->K+, these ratio followed by roots. The major Ione stored in the stem and root of U.setulosa is Mg+2(Table 5).
3.3. Comparative accumulation of elements in succulent and non-succulent halophytes.
Results shows among these both halophytic groups, elements accumulation in three parts, has been varying at each part. Succulent plants stored the majority of the component in foliar organs when in non-succulent plants is to be in root. The Mg+2 among these both groups, in non-succulent accumulation of Mg+2 in the stem is high when in succulents it is higher in foliar parts (Fig. 2).
3.4. Spearman's correlation coefficients studies
Statistical analysis showed significant interactions among elements in different parts of succulent and non-succulent halophyte plant species. The primary data were subjected to a correlation statistic tool, it reflected that in leaves Na+ and Ca+2 ions were negatively correlated (r =-1.000**) with each other. Root K+ and leaves Na+ has also highly negative relations (r =-1.000**). It was noted that Na+ and K+ content in stem and leaves respectively showed significant positive variation (r =1.000**). Similarly, the trend was observed in Ca+2 and Cl- content within the root and leaves respectively at a positive significant variation (r =1.000**). Correlation between K+ (Root) and Ca+2 (Leaves) showed significant variation (r =1.000**). There is a significant correlation between root Na+ and leaves for K+ content at the level of 0.01 (r =1.000**). An interesting significant correlation was noted for Ca+2 content of roots and Cl- leaves. Furthermore for the roots, Mg+2 and Na+, within the root and stem showed a highly significant positive correlation (r =1.000**), where root Cl- and stem Ca+2 showed a highly positive correlation (r =1.000**) (Table 6).
Considering the non-succulent halophytic group, it was noted that there is a strong positive correlation of Ca+2 content (r =1.000**) between stem and leaves of non-succulent species. A similar trend was observed between the Mg content of leaves with Na+ and Cl- content of stem at a significant level of 0.01 (r =1.000**). Cl- content of root and leaves showed a significant correlation between each other. There is also a significant positive correlation between stem Mg+2 and root Cl- with leaves Cl-. Interestingly, Cl- the content of stem was positively correlated with Na+ content of stem (r =1.000**). Whereas, some negative correlation also found, Mg+2 of leaves and K+ of the stem (r =-1.000**), Na+ and Cl- of the stem was strongly negative correlate with leaves K+ (r =-1.000**). Cl- of leaves and K+ of the stem also negative relations. Whereas within stem Mg+2, K+, root Cl- and stem K+ has a highly negative correlation. The overall findings reveled that Cl- showed maximum positive and negative correlation with different parts of the non-succulent with other mineral ions (Table 7).
