Nowe stanowisko storczyka – żłobika koralowego Corallorhiza trifida Châtel. stwierdzono na terenie kompleksu soligenicznych torfowisk w dolinie rzeki Kulawy w maju 2010 roku, podczas prowadzenia badań terenowych w rezerwacie przyrody „Dolina Kulawy”. Odnaleziono 33 osobniki żłobika koralowego, występujące w postaci dwóch skupień, zlokalizowanych w sąsiedztwie bezimiennego zbiornika wodnego. Aktualnie ta niewielka populacja nie wydaje się zagrożona, a w trakcie badań nie zaobserwowano potencjalnych zagrożeń dla istnienia populacji na terenie rezerwatu.

Dwulistnik muszy Ophrys insectifera L. jest w Polsce rośliną rzadką, objętą ochroną ścisłą. W pracy opisano dwa nowe stanowiska tego gatunku, odnalezione podczas prac terenowych prowadzonych na obszarze Pienińskiego Parku Narodowego w 2009 roku. Dane lokalizacyjne zostały uzupełnione o krótką charakterystykę warunków siedliskowych panujących na omawianych stanowiskach. Odnalezione populacje, ze względu na skrajnie niską liczebność, należy objąć stałym monitoringiem

Introduction. Inertial training is a little known strength training method. Very few research papers describing the effectiveness of inertial training have been published. Many questions regarding inertial training still remain unanswered. What do we know about the methodology of inertial training? What is the efficacy of inertial training? What are advantages and disadvantages of different inertial devices? The present study attempts to explain the concept of inertial training and recapitulate the state of current knowledge about this training method. Methods. Material for this study consisted of publications retrieved from the PubMed, Springer, SPORTDiscus, and MEDLINE databases. Results. There has been only one scientific study concerned with the optimal methodology of inertial training. In the present paper the authors discuss a method for optimal muscle loading during inertial training. However, most articles reveal a high efficacy of inertial training for strength and power improvement in a relatively short time. Inertial training can evoke functional changes and can be useful in sport practice. There have been a few types of inertial devices, and in the last five years two devices have been designed which enable the development of inertial training methodology: ITMS and Cyklotren. However, since inertial training methodology still remains insufficiently examined, further research is needed in the area. Conclusions. Considering its high effectiveness, inertial training appears to be a highly promising strength training method. However, the methodology of inertial training must be further developed. The application of the new Cyklotren inertial device can greatly facilitate this objective.

Most flowering plants, including important crops, require double fertilization to form an embryo and endosperm, which nourishes it. Independence from fertilization is a feature of apomictic plants that produce seeds, from which the plants that are clones of the mother plant arise. The phenomenon of apomixis occurs in some sexual plants under specific circumstances. Since the launch of a fertilization-independent mechanism is considered a useful tool for plant breeding, there have been efforts to artificially induce apomixis. We have been able to produce fertilization-independent endosperm in vitro in Arabidopsis over the last few years. This paper demonstrates the methods of improving the quality of the endosperm obtained using plant and mammalian steroid hormones. Additionally, it shows the study on the autonomous endosperm (AE) formation mechanism in vitro. This paper examines the effect of exogenous steroid hormones on unfertilized egg and central cell divisions in culture of unpollinated pistils of Arabidopsis Col-0 wild-type andfie-1 mutant. All media with hormones used (estrone, androsterone, progesterone, and epibrassinolide) stimulated central cell divisions and fertilization-independent endosperm development. The stages of AE development followed the pattern of Arabidopsis thaliana wild type after fertilization. Subsequent stages of AE were observed from 2-nuclear up to cellular with the most advanced occurring on medium with 24-epibrassinolide and progesterone. The significant influence of mammalian sex hormones on speed of AE development and differentiation was noticed. Using restriction analysis, the changes in methylation of FIE gene was established under in vitro condition. The authors of this paper showed that Arabidopsis thaliana has a high potency to fertilization-independent development.
