The researches were carried at the Frasinu Society in Buzău County, located on the outskirts of Buzău. The orchard was established in the spring of 2010, with the 'Caroa de Rei', 'Sharon', 'Ogosho' and 'Rojo Brillante' varieties, of nine years old. The trees were planted at a distance of 4 x 4 m. Four variants (represented by the variety), cultivated in 4 repetitions, were studied. Observations on the fruits were made from 2014 until 2018. Determinations were made on the average fruit weight, the height of the fruit and the diameter of the fruit and the shape index was calculated. From the chemical point of view, determinations have been made regarding the content in soluble solids determined by refractometry. The largest fruits were obtained in the 'Sharon' variety (190 g on average), followed by the 'Rojo Brillante' (180 g) and 'Ogosho' (174 g). The fruits of the 'Caroa de Rei' variety recorded a shape index of 1.14, and the 'Ogosho' variety had the lowest value of the shape index (0.64), the fruits being of the flattened form. The kaki fruit is sweet, due to its high content in soluble solids. The varieties studied had values higher than 10%, the sweetest variety being 'Caroa de Rei' (17.12%). Considering the quality of the fruits and the behavior of the trees during the experiments we consider that this species can be cultivated successfully in Romania. [ABSTRACT FROM AUTHOR]

Riverbed sediments morphometrical analysis can offer, along granulometric and petrographic analysis, relevant information on sediment source origin, transport environment and sedimentation process. Today, there are numerous descriptive indices for clasts shape and size, each one trying to evidence the influence of dynamic conditions and clasts petrography that are mobilized in certain transport environment, their shape at certain moments. Among these, this analysis focused on only 10 morphometric indices. The obtained data, either from direct measurements on 5,027 clasts or after index calculations, were processed and obtained a set of statistical parameter (average, median, standard deviation, etc.). Based on these data was assessed "optimal shape" for Trotuş riverbed gravels. Some parameters (like average value) were used to create frequency histograms for some morphometrical indices in sampling points and to make some mathematical modeling. [ABSTRACT FROM AUTHOR]
