PHYTOTOXICITY OF HALLOYSITE SUPPORTED IONIC LIQUID-LIKE PHASE (HNT-SILLP) CATALYST ON RAPHANUS SATIVUS L.
Nanotechnologies and nanomaterials are increasingly involved in the production of fillers, opacifiers, catalysts, semiconductors, cosmetics, microelectronic components and drug carriers with improved properties. Nevertheless, the production, use and disposal of nanomaterials, will inevitably lead to their release into the soil, with potential phytotoxicity on plants and negative impacts on economy, society and environment (1). In the last years halloysite nanotubes (HNT) emerged as promising materials with appealing perspective for technological applications. We have recently reported the generation of HNT derivatives carrying octylimidazolium moieties on the external surface (HNT supported…
Cytogenetical test to predict the vigour potential in Brassica seeds under long-term storage.
Preservation of intraspecific diversity in seed banks is a common strategy to frontier the loss of biodi- versity, however long-term storage inevitably results in the loss of a certain percentage of seeds, there- fore causing the genetic erosion of a seed collection. For this reason seed quality monitoring is of out- standing importance to ensure that the regenerated genetic material is representative of the endemic nat- ural diversity once reintroduced in the environment, as well as to preserve the genetic biodiversity of species economically relevant for modern agriculture. Ageing amplification tests, in which seeds under- go osmotic stresses, enable to detect little differences in the vi…
