The seeds of soybean cv. Aldana and spring wheat cv. Torka were soaked for 24 h in solution of zearalenone [ZEN, 2,4-dihydroxy-6-(10-hydroxy-6-oxo-trans-1-undecenyl)-benzonic acid lactone, 4 mg dm-3] and then they were sown in the pot experiment in an open vegetation hall. The after-effects of ZEN on growth of plants, net photosynthetic (PN) and transpiration (E) rates, stomatal conductance (gs), photochemical efficiency of photosystem II (PSII) and on final seeds yield, were determined. A significant increase of seeds yield was revealed in plants of both cultivars i.e. by 22% and 19% of seed (grain) number and by 28 and 24% of seed (grain) mass, in soybean and in wheat, respectively. The photosynthetic rate (PN) was stimulated during the juvenile and final phase by about 13.6% (average) in soybean plants. During other developmental stages, assimilation of CO2 was retarded. The response of CO2 assimilation in wheat plants was less pronounced as compared to that in soybean, but an increase of PN by over 24% near the final stage of development was observed. The quantum yield of PSII electron transport (ΦPSII) in soybean plants was changed after the treatment of seeds by ZEN similarly as for the rate of CO2, whereas in wheat it continued to gradually increase i.e. during the whole growth period. Changes of ΦPSII both in soybean and in wheat plants, as the response to ZEN treatment, were accompanied with an increase in the efficiency of changes occurring within the antenna (Fv'/Fm') as well as within centres of photochemical reactions (qp). The conclusion is that ZEN can affect plant growth and development in many ways, as well as in the status and functioning of the photosynthetical apparatus. Some of the effects can be very longlasting, as e.g. stimulation of production of seed yield in response to treatment of seeds with this substance. and J. Kościelniak ... [et al.].

In this article, I explore the relationship between the reproduction of hegemonic discourses of national representation in the reception of literature in translation and processes of canonization. I argue that World Literature as a paradigm hinders our efforts of overcoming the burdens of canonization. As a case study, I analyze the implications of building and reproducing a canon of Japanese literature in translation in the United States for the way Japan has been represented in public discourse in the last thirty years. I will focus on the reception of Murakami Haruki as the contemporary representative of the canon of Japanese literature in translation. My goal is to examine how the circumstances of Japanese literature in translation perpetuate mechanisms of canonization in their engagement and legitimation of an ongoing logic of representation that is non-confrontational with agents in power. I aim to test the extent to which studying the reception of East Asian literature in translation can help us promote a broader discussion on the appropriateness of such frameworks in our understanding of the contemporary literary phenomenon.
A multiplicative functional on a graded connected Hopf algebra is called the character. Every character decomposes uniquely as a product of an even character and an odd character. We apply the character theory of combinatorial Hopf algebras to the Hopf algebra of simple graphs. We derive explicit formulas for the canonical characters on simple graphs in terms of coefficients of the chromatic symmetric function of a graph and of canonical characters on quasi-symmetric functions. These formulas and properties of characters are used to derive some interesting numerical identities relating multinomial and central binomial coefficients.
The potential importance of CO2 derived from host tree respiration at night as a substrate for night time CO2 uptake during CAM was investigated in the subtropical and tropical epiphytic vine Hoya carnosa in a subtropical rainforest in north-eastern Taiwan. Individuals were examined within the canopies of host trees in open, exposed situations, as well as in dense forests. Although night time CO2 concentrations were higher near the epiphytic vines at night, relative to those measured during the day, presumably the result of CO2 added to the canopy air by the host tree, no evidence for substantial use of this CO2 was found. In particular, stable carbon isotope ratios of H. carnosa were not substantially lower than those of many other CAM plants, as would be expected if host-respired CO2 were an important source of CO2 for these CAM epiphytes. Furthermore, laboratory measurements of diel CO2 exchange revealed a substantial contribution of daytime CO2 uptake in these vines, which should also result in lower carbon isotope values than those characteristic of a CAM plant lacking daytime CO2 uptake. Overall, we found that host-respired CO2 does not contribute substantially to the carbon budget of this epiphytic CAM plant. This finding does not support the hypothesis that CAM may have evolved in tropical epiphytes in response to diel changes in the CO2 concentrations within the host tree canopy. and C.-C. Hsu ...
