Seed production variety characteristics

Complex evaluation of selection samples in various conditions growing in mountains and foothills in natural plant communities, in pme and mixed crops secures creation of valuable basic material for formation of a meadow-pasture variety with such traits as high competitiveness, qualitative characteristics and maximal seed productivity. 

The history of the use and identification of Cannabis sativa L. is long and complex. It is one of the oldest cultivated plants, used for the production of oil from the seeds, and fibre from the stems for rope and fabrics, and has long been used as a psychoactive drug due to the presence of cannabinoids in the resins produced by the plant. Indeed, there is evidence of cannabis use from Neolithic burial sites. The name Cannabis sativa was first used in Linnaeus Genera Plantarum in 1753, but since that publication there has been considerable debate about the number of species and varieties that exist - this has been recently summarized succinctly by Gigliano [1]. The debate has centred on (i) the characteristics of the fruit, and (ii) meiosis and pollen fertility. It is now generally accepted, however, that there is only one species, namely Cannabis sativa L., which exhibits great diversity due to both selection in the wild and in the cultivated environment. 

The seeds peptide MALDI profile proved to be suitable in characterizing grape varieties. This result was confirmed excluding, or by evaluating as being of minor influence, the other factors that might contribute to the protein profile the harvest year, zone of production and vineyard treatments. To achieve it, seeds of Raboso Piave grape samples collected from different vineyards and harvested in different years were studied. The 3D plot of Fig. 10.3 shows that the profile is maintained in particular the species at m/z 6113, which is characteristic of this variety, is detected in the spectra of all samples.
