Interspecific compatibility and self-compatibility in Pyrus communis, P. pyraster and P. salicifolia were evaluated. Degree of compatibility was determined by means of fluorescence microscope. Self-incompatibility evaluated on the basis of the pollen tubes growth showed that two cultivars of P. communis (Bera Hardy and Lukasówka) were self-compatible and the other three cultivars were self-incompatible. All ecotypes of P. pyraster are self-incompatible. In interspecific crosses full inter-incompatibility or unilateral self-incompatibility was observed.

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.
