“…The development of suberin lamellae in both Brassica species studied corresponds with Cd concentration in plants. Similarly, development of suberin lamellae associated with reduced Cd uptake was reported also in maize by Redjala et al (2011). Relation between differences in Cd uptake into root and shoot, and development of apoplasmic barriers was ascertained also by Vaculík et al (2009Vaculík et al ( , 2012.…”

“…Ultraviolet illumination was used for fluorescence microscopy (excitation filter TBP 400 + 495 + 570, beam splitter TFT 410 + 505 + 585, and emission filter TBP 460 + 530 + 610, the wavelengths are in nm). To overcome the problem with different lengths of roots from each treatment and interspecific differences, the distance of the suberin lamellae formation from the root apex was expressed in percents of total root length (Vaculík et al 2009;Redjala et al 2011). …”

The objective of this study was to determine the effect of silicon (Si) and cadmium (Cd) on root and shoot growth and Cd uptake in two hydroponically cultivated Brassica species (B. juncea (L.) Czern. cv. Vitasso and B. napus L. cv. Atlantic). Both species are potentially usable for phytoextraction. Inhibitory effects of Cd on root elongation were diminished by the impact of Si. Primary roots elongation in the presence of Cd + Si compared with Cd was stronger and the number of lateral roots was lower in B. juncea than in B. napus. Cd content per plant was higher in B. napus roots and shoots compared with B. juncea. Suberin lamellae were formed closer to the root apex in Cd + Si than in Cd treated plants and this effect was stronger in B. napus than in B. juncea. Accelerated maturation of endodermis was associated with reduced Cd uptake. Cd decreased the content of chlorophylls and carotenoids in both species, but Si addition positively influenced the content of photosynthetic pigments which was higher in B. napus than in B. juncea. Si enhanced more substantially translocation of Cd into the shoot of B. napus than of B. juncea. Based on our results B. napus seems to be more suitable for Cd phytoextraction than B. juncea because these plants produce more biomass and accumulate higher amount of Cd. The protective effect of Si on Cd treated Brassica plants could be attributed to more extensive development of suberin lamellae in endodermis.

“…The objective of studies associating the maize (Zea mays L.) root anatomical characters have usually been focused on identifying their relationship with specific soil conditions, such as flooded areas (Magalhães et al, 2009), compacted soils (Bergamin et al, 2010), regions suffering water stress (Chimungu et al, 2014), and soils with an excess of certain chemical elements (Redjala et al, 2011). On the contrary, studies about the association between the anatomical and agronomic characters of the plant itself have not been emphasized.…”

Indirect selection based on highly correlated characters is a common strategy in genetic improvement to quickly and accurately identify genotypes with good agronomic characteristics. The objective of this research study was to quantify existing associations between root agronomic and anatomical characters in maize (Zea mays L.) populations for possible indirect selection. The following agronomic characters were considered: Plant height, ear insertion height, relative ear position, plant lodging, plant breakage, and grain productivity. Measured anatomical characters included total root area, central cylinder area, epidermis thickness, exodermis thickness, endodermis thickness, cortical parenchyma thickness, number of metaxylem vessels, phloem area, cortex thickness, and metaxylem area. The genotypic correlation analysis showed significant associations at the 1% probability level between the following anatomical and agronomic characters: Endodermis thickness and plant height, exodermis thickness and plant breakage, and exodermis thickness and grain productivity. The canonical analysis of variance showed significant effects by the chi-square test for three of the five canonical pairs. The first canonical pair showed a positive relationship between plant height and total root area (4.142) and a negative relationship with the central cylinder area (-4.080), indicating that genotypes with greater total root area and lower central cylinder area can give rise to larger plants. These results indicated the possibility of an indirect selection of taller or shorter plants in the earlier growth stages using anatomical root characters.
