Augmented vascular bundle
area is an imperative trait for survival in damaged environments.
It must be noted, however, that some characters that are typically found in the leaves of Polygonaceae, as ochrea at the base of the petiole, petiole with several vascular bundles
, stomata usually present on both surfaces, vascular bundles
of the veins accompanied by sclerenchyma, and 2-4 layers of palisade parenchyma (Metcalfe & Chalk, 1957), were not registered in cotyledons and eophylls of R.
area (um2): Rosa Gruss-an-Teplitz contained highest vascular bundle
area than other species and maximum value was recorded under untreated wastewater (64924.
Digitaria insularisshowed differences in stomata, vascular bundle
, parenchyma, xylem/ phloem relation and trichomes that caninfluence the different glyphosate efficacy between biotypes.
The vascular bundle
concentration is the highest on the top part.
In general, the vascular bundles
are a little larger and less numerous per unit area, whereas parenchyma cells are unlignified in the Tight' zones, in contrast to the bundles and parenchyma in the 'dark' zones.
Leaf vascular bundle
penetration by SB has been previously reported in only 2 species of scales (Heriot 1934; Washington & Walker 1990).
Collateral vascular bundles
are surrounded by a parenchyma sheath, unrelated to sclerenchyma (Fig.
In the dorsal dehiscence region is pointed out a large vascular bundle
of each carpel.
Viewed in cross section, they appear just like the vascular bundle
in a stem.
This line appears white because of the presence of the lateral thoracodorsal nerve and vascular bundle
Some bark can be removed at the point of contact with the soil to expose the vascular bundle
, the area which will provide the roots.
