The micromorphological characteristics of the pollen grain sculpture is one of the most important diagnostic traits in plants. Pollen grains in various species of the subfamily Prunoideae are characterized by variations in size, shape and exine sculpture. In the present work, for the first time, the micromorphology of pollen grains of fourteen cultivars from five fruit tree species of the genus Prunus was compared. Morphometric observations and analysis of pollen grains were performed using light and electron scanning microscopy. In terms of size, the pollen grains studied were classified as medium sized and large. Their shape was determined to be prolate, subprolate, or prolate spheroidal. The striae in the exine of P. armeniaca run parallel and can be branched or curved. The sculpture of P. persica grains shows elongated extending paralel regular and irregular striae, dichotomously branched. Regularly arranged, or at places branched, striae are found in the exine of P. avium pollen grains. The ornamentation of P. cerasus grains is composed of elongated striae, sometimes slightly curved or with a tendency to intertwine. The exine of P. domestica grains is characterized by forked, arched striae. The stria thickness differs significantly between cultivars within the species, while the groove width differs only between some species and cultivars. The obtained results on the exine sculpture of pollen grains can be used in the taxonomy of species of the genus Prunus.

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.

The polyprenol pattern in leaves of fruit trees belonging to the Rosaceaei (genera: Prunus, Malus) and Cornaceae (genus: Cornus) families is presented. The content of polyprenyl acetates varied within plant species between 10 to 50 mg per gram of dry weight. In genus Prunus, Cornus and in representatives of species Malus domestica, a mixture of polyprenols composed of 18, 19, 20, 21 isoprene units was found. In 6 species of genus Prunus ( sour-cherry ): P. serrulata-spontanea, P. yedoensis, P. fruticosa. P. kurilensis, P. subhirtella and P. incisa the presence of a second polyprenol family, i.e. the group of prenologues consisting of prenol -35, -36, -37, etc. up to -42 was detected.

This paper deals with the evaluation of the in fluence of paclobutrazol (N-dimethylaminosuccin - amic acid) and 2-naphtoxyacetic acid on rooting and growth of GF-677 hybrid peach rootstocks. The influence of these substances on the average number of roots per plant, the aver age length of roots per plant and the height of plants was evaluated as well as the effect of the addition of paclobutrazol before and after media sterili sation. As the ob tained results indicate, plants, which were rooted on media with paclobutrazol and with out auxin had the low est number of roots per plant. Paclobutrazol showed a statistically significant negative effect on both the length of roots and the height of plants. It canbe concluded that, for the rooting of GF-677 rootstock it is help ful to use auxin plus paclobutrazol in concentration 0.43 μM. Higher concentrations affect inhibition, mainly in height of plants 14 days after transplant to soil.

In leaves of various species of fruit-trees belonging to the Rosaceae family, large amounts of polyprenyl acetates (0.5-5.0% of dry weight) were found. Discrete constant differences of polyprenol spectrum characteristic of each genus studied: Mains, Pruttus and Pyrus were observed. In each species poly-ris-prenols composed of 19 and 20 isoprene units were predominating. In one of the 23 studied species (Prunus incisa) a fraction of long-chain polyprenols composed of 35—45 isoprene units was also present. It seems that this type of unusually long-chain polyprenols could occur also in other plants of the Rosaceae family

Rosaceae fruit trees are characterized by gametophytic self-incompatibility, with their production typically requiring artificial pollination or pollination tree is required in production. Both of these solutions cause reductions in production efficiency, and self-incompatibility has become a major issue in agricultural biology, and as such, has been extensively studied. In this review, we discuss the relationship between S-RNase content in the style and self-incompatibility, and the role of the SLF gene in stamen-determining factor. Considering mutations in self-compatibility-related genes and self-compatibility in polyploid fruit trees, we discuss the potential mechanisms of self-incompatibility. Based on a preliminary study of the role of pollen tube Ca2+ gradients in self-incompatibility in Pyrus, we propose a new mechanistic model of self-incompatibility taking into account the effect of Ca2+. We also discuss the potential for hormone regulation to be used to control selfincompatibility in Rosaceae fruit trees.

Despite senescence-induced chlorophyll depletion in plants has been widely studied, the enzymatic background of this physiologically regulated process still remains highly unclear. The purpose of this study was to determine selected biochemical properties of partially purified fractions of chlorophyllase (Chlase, chlorophyll chlorophyllido-hydrolase, EC 3.1.1.14) from leaves of three Prunus species: bird cherry (Prunus padus L.), European plum (Prunus domestica L.), and sour cherry (Prunus cerasus L.). Secondarily, this report was aimed at comparing seasonal dynamics of Chlase activity and chlorophyll a (Chl a) content within investigated plant systems. Molecular weight of native Chlase F1 has been estimated at 90 kDa (bird cherry) and approximately 100 kDa (European plum and sour cherry), whereas molecular mass of Chlase F2 varied from 35 kDa (European plum) to 60 kDa (sour cherry). Furthermore, enzyme fractions possessed similar optimal pH values ranging from 7.6 to 8.0. It was found that among a broad panel of tested metal ions, Hg+2, Fe+2, and Cu+2 cations showed the most pronounced inhibitory effect on the activity of Chlase. In contrast, the presence of Mg+2 ions influenced a subtle stimulation of the enzymatic activity. Importantly, although Chlase activity was negatively correlated with the amount of Chl a in leaves of examined Prunus species, detailed comparative analyses revealed an incidental decrement of enzymatic activity in early or moderately senescing leaves. It provides evidence that foliar Chlase is not the only enzyme involved in autumnal chlorophyll breakdown and further in-depth studies elucidating this catabolic process are required.

The bird cherry-oat aphid (Rhopalosiphum padi L.) development on primary host (Prunus padus L.) was studied in Poznan in 2007–2008. First fundatrices of R. padi were observed already on the bird cherry in March in both years. The largest condensation of population was observed in May. At the second decade of May numerous winged morphs were formed and spring migration into the secondary hosts started. Re-emigrants in September were observed and the oviparae and males in second decade of October gave birth. In spring observations fertilized eggs (from which aphids hatched) made up 89% and 81% respectively. The meeting of factors inducing the formation of individual morphs of R. padi and the deadlines of the migration on host-plants has a special meaning in the aspect of transfer of viruses by the anholocyclic forms of this species.
