The project led to the development of 118 monitoring factsheets, providing an operational guidance for 107 vascular taxa, 10 bryophytes and 1 lichen taxon. Each factsheet includes information on the species (distribution, biology, ecology, conservation status, threats, etc.) and the description of field methodologies for the detection of the two main reporting parameters, i.e. population size and habitat quality. Practical information to plan field activities are also given. Protocols were designed to address the requirements of the European reporting system with the aim to standardize future monitoring activities, optimize efforts at national scale and overcome some current problems related to data heterogeneity and discrepancies from the EC standards. More than 60 botanists collaborated to ide...

The outcomes showed a general negative conservation status for plant species, with the worst situation being in the Mediterranean bioregion. At the National level, significant monitoring and conservation activities are required.

Directive 92/43/EEC. Seeds of B. insularis, collected in 2010 from three Sardinian populations [Planu Sartu and Masua (SW Sardinia) and Isola dei Cavoli (SE Sardinia)], were analyzed through an image analysis system. In addition, germination tests were conducted on seeds from each population, in the light (12/12), at a range of constant temperatures (5-25°C) and at an alternating temperature regime (25/10°C). The morphocolorimetric analysis, clearly identified seeds from
different populations (in 97.6% of the cases) and discriminated three chromatic categories (black, orange and brown) for seeds belonging to the “Isola dei Cavoli” population, with a percentage of correct identification of 90%, while seeds of the two other populations were morphologically homogenous. Germination ranged from 45% to 60% for “Planu Sartu” and “Isola dei Cavoli”
populations, respectively and temperature had not a significant effect. Seed moisture content (%) did not vary significantly among chromatic categories, highlighting as heterogeneity was not related to different stages of seed maturation. Germination was highly influenced both from colour and temperature, and high germination percentages (ranging from 50% to 80% for black and orange seeds, respectively) were detected at 5°C. These results showed the significant variability in morphology and germination among B. insularis seeds from different provenances, indicating the presence of morphological and physiological seed heterogeneity in this species.
The main aim of the project is to use some of seed biometric features, measured with computer-aided image analysis techniques, to characterize the studied Vitis vinifera L. cultivars. The recorded data were used to implement statistical classifiers able to discriminate among the cultivars, and comparing them with archaeological seed lots founded in Sardinia, in order to improve the knowledge about the origins of viticulture in Sardinia. During the first year, some sample bunches from old grapevines of different ages were collected in the North-Central Sardinian territory. In particular, they are from Bono (NU), Oliena (NU), Atzara (NU) and Pattada (SS). Seeds were extracted from the bunches and cleaned. Digital images of samples, consisting of 100 seeds (when available) for each seed lot, were randomly disposed on a flatbed scanner, acquired and processed for the morpho-colorimetric analysis. A total of 137 phenotypical descriptors and the mean seed weight was measured in each seed. The data were statistical analyzed, applying the stepwise Linear Discriminant Analysis method (SPSS Inc. 2006). Studying plants from 10 to 80 years old, the analysis showed that the seeds of the cultivar “Muristellu”, reduced their dimensions, increasing their luminosity and minimum diameter, during the time.
Moreover, the system allowed to correctly identify the compared seed lots with percentages of ca. 96%.
Analysing the seed lots of the cultivar “Arvesiniadu”, collected from plants from 20 to 120 years old, it was possible to underline a high level of similarity. Nevertheless, the studied seed lots showed a significant variation in seed colour intensity and seed roundness, both directly proportional with the age of the grapevines. These preliminary results prove that the age of the plant can affect the seed aspect. This is probably due to the modified agronomical practices during the last century and in particular in the recent decades. Anyway, these achievements could be useful in order to better understand the origin of viticulture in Sardinia.

conservazione dei vitigni autoctoni della Sardegna” developed at the enterprise “Azienda Gostolai S.A.S. di

velutina and S. ichnusae seeds germinated up to 300 mM NaCl, while S. badaroi until 100 mM. For all the species, salt did not affect seed viability and recovery did not decrease whit increasing salinity and temperature, except for S. badaroi. Inter-population variability both in salt tolerance and recovery was detected for S. velutina. The adding of KNO3 did not affect germination and its recovery under salt conditions. Our results highlighted that these species have their optimum of germination during autumn-winter when, under the Mediterranean climate, water availability is highest and soil salinity levels are minimal, but they are also able to germinate until spring.
