Seeds of 27 species of Moehringia and four related representatives of Arenaria (old M. sect. Pseudomoehringia) were examined by scanning electron microscopy. Novel morphological features were observed in addition to those found in a previous similar study. The new information thus obtained provided new insight into the taxonomic value of...
Phytotoxicity tests were performed to evaluate their application in environmental monitoring on different substrates, e.g. commercial detergents (D1, D2) and surface water from the dismissed Cu and Fe mine of Libiola (NW Italy), respectively. Seeds of Vicia faba were grown in 0, 10, 30, 60, 100 g/l of D1 and D2. Number of germinated seeds and...

Primula allionii is a primrose endemic to the Maritime Alps. In order to evaluate its conservation status, we investigated its demographic structure and reproductive success. We studied the plant in three different plots in Roya Valley (France), representing the different structure of cliffs where the plant usually lives. The mean dimensional...

The function of diaspores in Moehringia genus was investigated and field observations pointed out the elaiosome role in seed predation and dispersal by ants. Histochemical stainings underlined the presence of lipid in the strophiole. Our results are congruent with the hypothesis that some representatives of the genus Moehringia adopt...
Primula allionii is a primrose endemic to Maritime Alps. The plant was studied in three different plots representing the different structures of cliffs where the species usually lives. The reproductive success of the plant was analyzed in order to evaluate its conservation status. Mean plant dimensions and distribution within the plots were...

Seeds of 30 species of Moehringia and 12 representatives of the Caryophyllaceae were examined with the Scanning Electron Microscope. High diversity was found in seed coat micromorphology, and a number of novel morphological features have been observed. Comparison with other representatives of the Caryophyllaceae has provided new insight into...

High nickel (Ni) levels exert toxic effects on plant growth and plant water content, thus affecting photosynthesis. In a pot experiment, we investigated the effect of the Ni concentration on the physiological characteristics of the Ni hyperaccumulator Alyssoides utriculata when grown on a vermiculite substrate in the presence of different...
This study investigated the accumulation and distribution of nickel in the leaves and roots of the Mediterranean shrub Alyssoides utriculata to assess its potential use in phytoremediation of Ni contaminated soils. Total (AAS and ICP-MS) Ni, Ca and Mg contents were analyzed in the plants and related to their bioavailability (in EDTA) in...
