Abstract: Among the compounds stored by plants, several functions are assigned to fructans, such as source of energy and protection against drought and extreme temperatures. In the present study we analyzed the anatomy and distribution of fructans in vegetative organs of Dimerostemma vestitum (Asteraceae), an endemic species from the Brazilian campos rupestres. D. vestitum has amphistomatic and pubescent leaves, with both glandular and non-glandular trichomes. In the basal aerial stem the medulla has two types of parenc… Show more

“…Conversely, the 0–5 cm fraction had the lowest concentration of sucrose and highest concentration of fructan. The observed reduction in fructan concentration in plant height is in line with the findings of Sprague and Sullivan () and Silva, Vilhalva, Moraes, and Figueiredo‐Ribeiro (). Sprague and Sullivan () found that the fructan concentration in orchard grass ( Dactylis glomerata ) was highest in lower stem followed by upper stem and upper leaf blades had the least concentration of fructans.…”

“…Anatomical studies performed on 'candeia' roots confirmed the great capacity of root blossom emission in species belonging to the family Asteraceae (Appezzato-da-Glória et al, 2008). Several authors have attributed this regrowth ability to the presence of fructan-type inulin crystals in the root cells (Assega and Carvalho, 2004;Assega et al, 2011;Santos et al, 2016;Silva et al, 2015). The occurrence of crystals on the walls of the vessel elements of the secondary xylem ( Figure 2F-G) is in accordance with what Tertuliano and Figueiredo-Ribeiro (1993) described for other species of the Asteraceae family.…”

“…The legislation foresees that natural stands that can be exploited should hold at least 70% of these tree species and that this predominance is reestablished through the conduction of natural regeneration in the exploited area (Belo Horizonte, 2013). Although seminal propagation is considered to be the main strategy adopted in the current 'candeia' management plans (Pérez et al, 2004), alternative forms of plant perpetuation may occur through periodic restriction of the environment (Appezzato-da-Glória et al, 2008;Silva et al, 2015). These authors have been conducted morpho-anatomy studies in root plants of Asteraceae family with the aim to identify structures and sources able to promote the regenerative shoots in plants, after natural or anthropogenic disturbances.…”

“…The cross-sections of clove samples from each garlic cultivar were prepared and fixed in 70% ethanol for 48 h. Following the methods of Gerlach (1977) as cited by Silva et al (2015), they were then stained with safranin and fast green to distinguish the plant cell structures (Fig. 3).…”
