No full textFloristic notes on a peculiar Acer opalus mill. ssp. obtusatum (Waldst. et Kit. ex Willd.) community on Gargano (Apulia, Italy)
No full textThe results of floristic investigation into the most representative plant community of Acer opalus subsp. obtusatum growing on Gargano Promontory (Apulia, Italy) are presented. The taxon is in the Regional Red List of plants of Apulia, with lower risk (LR). In all, 126 taxa were recorded, exsiccata of which were stored in the Herbarium Horti Botanici Barensis (BI), while 15 of them are considered important from a conservation point of view. For these species a detailed account is provided
Lolium multiflorum Lam. cvs germination under simulated olive mill wastewater salinity and pH stress
No full textThe agronomic use of olive mill wastewaters (OMWs) is limited by some constraints, such as high salinity, acidity, and phenolic compounds that exert phytotoxic and antimicrobial effects. Many researches have been focused on OMW polyphenol effects on germination, but only few on the combined effects of salinity and acidity. In this paper, on Lolium multiflorum Lam., the effects on germination of pH and osmotic potentials similar or higher to those found in OMWs have been investigated. The studied salinity and pH levels did not affect final germination of L. multiflorum, but in some cultivars they significantly enhanced T50 and consequently reduced initial root growth. Thus, in this species moderately tolerant to salinity, the reduction of germination determined by OMWs cannot be attributed to the osmotic stress and/or to the low pH, but mainly to polyphenols. This research emphasizes the possibility of obtaining good crop establishments after spreading OMWs on soil, choosing herbaceous species tolerant to salinity once polyphenols have been inactivated
