For phytomass production, water salinity had significant effect (p < 0.01) on petiole
dry phytomass (PDP) and leaf dry phytomass (LDP), and there were no differences among the levels of manure or even effect of the interaction between factors on any of the variables (Table 3).
The values of Na:Ca ratio of leaves, stem + petiole
, and absorption roots were higher for plants cultivated under salt stress (Figure 2B).
Branches without persistent spinules, petioles
[+ or -] smooth, 1(--2) mm wide, leaves 2-3.5(-5) cm wide, calyx lobes oblong, 4-5 mm long, appressed pubescent on both surfaces, petal apices not reflexed, anthers rounded ...
For plants grown without salt stress (control plants), the highest sodium ([Na.sup.+]) concentration was observed in the absorption roots (AR) and the lowest in the stem + petiole
0.5 mm long, caducous on the old parts, intense on the young branches, distributed on the branches, stipules, petioles
, rachis, leaflets, inflorescences, bracts, pedicels, margin with sepals and abaxial surface with the petals.
Completely randomized design was used with 4 factorial (2 x 5 x 3 x 2) (Medium: MS x B5, TDZ 5 concentrations x Explants: petiole
, leaf, node x Source of explants: field, in vitro) shoot regeneration experiment.
Both cultivations in water showed same diameter of the petioles
and stems (Figures 11 and 12), while smaller diameters were found in the soil cultivation (Figure 13).
Observed measurement ranges for the quantitative characters revealed that LBL, LBW and petiole
length were most significant at P<0.01 (Table 5).
Two of these (1 active and 1 abandoned) were located on the petiole
of Euphorbia cotinifolia L.
were sorted thoroughly and the leaves were swept with a fine brush to remove associated organisms for subsequent identification.
Leaves opposite, decussate, equal in a pair, evenly spaced; petiole
0.6-2.2 cm long, terete in cross-section, with a pair of glands at base of petiole
, glabrous, covered with a dense clusters of scales (more evident when dry); blade ovate to elliptic, 9-27 x 5-12 cm, coriaceous, green adaxially, light green abaxially, apex acuminate, base cuneate to rounded, sometimes oblique, margin with scattered small teeth, glabrous adaxially, glabrate and with minute punctations abaxially, 4-5 pairs of main lateral veins, higher order of venation only evident abaxially.
