Caption: FIGURE 3: 3D SEM image (13X) bamboo culm Guadua angustifolia Kunth Rayada Amarilla showing vascular bundles. Red arrow indicates the direction where tissues around of the vascular bundle are becoming more compact.
In addition, it was observed only in Minasia the presence of a colorless parenchyma that lies in the middle of the mesophyll and connects the vascular bundles laterally (Figs.
This could be due to the discontinuity of vascular bundles as they cross the node area of the bamboo culm.
Evidence for the consequences of a barrier to solute diffusion between the apoplast and vascular bundles in sugarcane stalk tissue.
They quantitatively assessed: (1) diameter of the root; (2) thickness of the root epidermis; (3) count of cores of protoxylem; (4) diameter of the vascular cylinder of the root; (5) proportion of the stomata and (6) subsidiaries cells; (7) size of the bulliform cells; (8) thickness of the foliar mesophyll; (9) thickness of the group of fibers of the abaxial and adaxial foliar rib; (10) diameter of the central vascular bundle of the foliar blade.
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.
The study also established that the thermal decomposition of CC began at temperatures below 100[degrees]C, with its complete degradation occurring at temperatures close to 1000[degrees]C, releasing enormous amount of gases, while SEM analysis revealed compacted vascular bundles and fiber tissues linked to carbon-orientation that are among the features of CC that may favour high temperature gasification.
