Autonomy of science and art is an ideal of every civilized society. The distance between a certain society and this ideal depends on a large number of parameters, among which cultural enlightenment and consciousness of the main protagonists in realization of these two areas seem to be most important. Unfortunately, Serbia cannot boast with a high level of independency of creative processes. Nowadays, in formal sense, they enjoy a higher level of autonomy in terms of the state ideology; however, at the same time, they are essentially and basically restricted by it. The very notion of autonomy here is related to financial and, more than this, to ideological independence of free and creative thought, that is to the question to which extent scientific creativity manage to transcend current cultural-historical-social context and to find universal regularities of human civilization in it. Intensity of social changes and postmodern market ideologies are reflected both at official scientific policy and at internal determination of context and concept of ethnological/anthropological researching which quite often become trapped in the shallow of topicality.
To understand the interactive effects of O3 and CO2 on rice leaves; gas exchange, chlorophyll (Chl) fluorescence, ascorbic acid and glutathione were examined under acute (5 h), combined exposures of O3 (0, 0.1, or 0.3 cm3 m-3, expressed as O0, O0.1, or O0.3, respectively), and CO2 (400 or 800 cm3 m-3, expressed as C400 or C800, respectively) in natural-light gas-exposure chambers. The net photosynthetic rate (PN), maximum (Fv/Fm) and operating (Fq'/Fm') quantum efficiencies of photosystem II (PSII) in young (8th) leaves decreased during O3 exposure. However, these were ameliorated by C800 and fully recovered within 3 d in clean air (O0 + C400) except for the O0.3 + C400 plants. The maximum PSII efficiency at 1,500 μmol m-2 s-1 PPFD (Fv'/Fm') for the O0.3 + C400 plants decreased for all measurement times, likely because leaves with severely inhibited PN also had a severely damaged PSII. The
PN of the flag (16th) leaves at heading decreased under O3 exposure, but the decline was smaller and the recovery was faster than that of the 8th leaves. The Fq'/Fm' of the flag leaves in the O0.3 + C400 and O0.3 + C800 plants decreased just after gas exposure, but the Fv/Fm was not affected. These effects indicate that elevated CO2 interactively ameliorated the inhibition of photosynthesis induced by O3 exposure. However, changes in antioxidant levels did not explain the above interaction. and H. Kobayakawa, K. Imai.
