Opis:: Plant material obtained by pruning and production of deciduous fruit trees was evaluated as substrates for the production of the oyster mushroom, Pleurotus ostreatus. Lignified branches and stems from peach, apple, and pear trees were processed using a ripping machine to reduce the size of chips and to optimize disinfection. A completely randomized experimental design was proposed with six treatments (novel substrates) and one absolute control (100% hay substrate). Morphological variables such as thickness and diameter of the pileus, stipe length were assessed, as well as production variables (sprouting, fresh weight, and biological efficiency) and bromatological analysis (ash, ethereal extract, crude fiber, and crude protein). Apart from the 100%-hay substrate, biological efficiency ranged between 27% (100% apple tree as the substrate) and 140% (50% hay + 50% peach tree as the substrate). According to morphological analysis, the highest diameters were recorded from mixed substrates (50% hay + 50% wood), and a highly significant positive correlation was found between diameter and stipe length. Morphological parameters were not significantly correlated with biological efficiency. Analysis of biological efficiency confirmed that mixed substrates clustered together with 100%-wood substrates. Bromatological analysis showed that the mixed substrate (50% hay + 50% pear tree) had the highest protein content among the novel tested substrates. Bromatological parameters were not significantly correlated with biological efficiency. In conclusion, pruning residues from fruit trees can be valuable by using them as substrates for the cultivation of P. ostreatus. Production is quantitatively competitive with that using hay, on the condition that wood is mixed with hay.

Opis:: In this study pollen grains of 13 cultivars and 3 rootstocks belonging to 5 species (P. armeniaca, P. domestica, P. dulcis, P. persica, P. avium) of the genus Prunus collected from North-East Sicily were examined for the micromorphological characterization through the scanning electron microscopy (SEM). The length of polar axis (P) and the equatorial diameter (E) of grain, P/E ratio, the length of colpi (C), diameter of perforations (DP) and the number of perforations in 25 μm2 (PN), the width of muri (WM), the distance between muri (DM) and their number in 25 μm2 (MN), the width of grooves (WG) were measured and their variation was compared among studied taxa. Moreover multivariate statistical analysis was carried out to distinguish morphometric information from measured parameters. All pollen grains are trizonocolpate, isopolar, medium-large sized and their shape varies from prolate to perprolate. Regarding outline pollen grains are subtriangular in polar view and elliptic in equatorial view. Exine sculpturing is striate with perforations on grain surface. The arrangement of ridges appears roughly parallel but too sloped (sometimes curved) compared to polar axis, or branched and oriented in different directions, or perfectly parallel or more irregular with bifurcated ridges often sinuous. The analyses showed a great variability (particularly in P. domestica cultivars) related in some cases to the diversity in the morphological features of the leaves and the fruits of the investigated entities.

Tytuł:: Influence of hand thinning of flowers and fruits on yielding and fruit quality of apples cultivar Szampion

Szampion cultivar
Opis:: The thinning of flowers and fruit sets did not change the strength of tree growth in a signifi cant way. Szampion cv. trees on rootstock A 2 grew better than on M.7. The trees of Szampion RENO cv. grew signifi cantly worst. The thinning of flowers and fruit sets decreased the yield from a tree and the total yield from 1 ha of the studied biological material. Flower thinning slightly increased the mean commercial yield as compared to the control trees. Thinning of 50% of flowers at the stage of the pink bud and sets after the June fall decreased the number of fruits on the trees of Szampion cv. grafted on M.7. It was only in 2004 that the flower thinning treatment signifi cantly increased the fruit weight. Flower thinning increased the percentage of fruits with a diameter of over 7 cm in the case of Szampion cv. trees grafted on M.7. This treatment considerably (in 2006 signifi cantly) improved fruit colouring. A positive reaction to fl ower thinning was also observed in Szampion RENO trees. In the case of Szampion cv., which shows a tendency to excessive fruit setting and small fruits, it is better to apply flower thinning eliminating the excess of sets in the period of cell division in growing fruits than do it later, after the June fall. The inflorescence removal treatment requires much more time than thinning of fruit sets.
Przerzedzanie kwiatów i zawiązków nie zmieniało istotnie siły wzrostu drzew. Drzewa odmiany ‘Szampion’ na podkładce A 2 rosły silniej niż na M.7. Istotnie najsłabiej rosły drzewa odmiany Szampion RENO. Przerzedzanie kwiatów i zawiązków zmniejszało plon z drzewa i sumaryczny plon z hektara badanego materiału biologicznego. Przerzedzanie kwiatów zwiększało nieznacznie średni plon handlowy w porównaniu do drzew kontrolnych. Przerzedzanie 50% kwiatów w fazie różowego pąka i zawiązków po opadzie czerwcowym zmniejszało liczbę owoców na drzewach odmiany Szampion okulizowanych na M.7. Tylko w 2004 roku zabieg przerzedzania kwiatów istotnie zwiększał masę owocu. Przerzedzanie kwiatów zwiększało procent owoców o średnicy powyżej 7 cm w przypadku drzew odmiany Szampion okulizowanych na M.7. Zabieg ten poprawiał znacznie (w 2006 roku istotnie) wybarwienie owoców. U drzew odmiany Szampion RENO stwierdzono także pozytywną reakcję na przerzedzanie kwiatów. W przypadku odmiany Szampion wykazującej tendencję do nadmiernego zawiązywania i drobnienia owoców bardziej korzystne jest stosowanie przerzedzania kwiatów eliminujące nadmiar zawiązków w okresie podziału komórek w rosnących owocach niż późne przerzedzanie zawiązków po opadzie czerwcowym. Zabieg usuwania kwiatostanów wymaga większego nakładu czasu pracy niż przerzedzanie zawiązków.

Opis:: The same young cropping ‘Regina’ sweet cherry trees were foliar treated with prohexadione-calcium (Pro- Ca) in two consecutive years at a concentration of [ 125, 125 x 2, 250 ]-(A) and [ 250, 375, 500 ]-(B) mg ProCa l-1, respectively. The following year some trees from A-treatments were left untreated to observe carry-over effects (C). None of A-treatments influenced tree trunk, shoot extension and internode growth, whereas B-treatments reduced shoot extension and internode length, simultaneously increasing flower bud density, particularly by 500 mg ProCa l-1. There were no carry-over effects produced by C-trees, except some retardation in shoot extension. None of the treatments influenced the tree cropping level. Fruit diameter was reduced by A-treatments, but fruit shape (L/D ratio) and mass were reduced by treatments B, and such reduction was also exhibited by C-trees (residual effects).
