Food consumption was measured during the day (lights on) and the night (lights off) and compared between one outbred and 9 inbred strains of mice (CBA/Kw, C3H, DBA2, KP, BALB/c, C57BL, B10.Amst , B10.BR, B10.BR Y-del) in age groups 30-60, 60-90, 90-120, and more than 120 days. Outbred mice and animals from B10 sublines ate significantly more during nocturnal darkness. Day and night food consumption was similar in KP animals. In mice from the remaining strains there was an apparent age-related shift from nocturnal towards diurnal eating habits.

Two components of mating behavior, mating latency and duration of copulation, were investigated in Drosophila melanogaster males from three different ..nutritional.. strains, reared for more than 35 generations on banana, tomato and cornmeal-agar-yeast substrates. Males from different strains did not differ according to mating latency and duration of copulation. Also, the sizes of males from different strains did not contribute to these behavioral traits.

Inheritance of water use efficiency (WUE) at the whole-plant level was investigated in a diallel set (Ps+F2s) of spring barley. Plants were grown in 9 dm3 pots under optimal conditions, low NPK nutrition and low soil moisture. GCA effects were found to be of major importance for the variance in vegetative and economic WUE measures. A significance of SCA effects was observed only under nutrient and soil moisture stresses. The stress conditions used did not considerably affect the sign and magnitude of combining ability effects. Consistency between GCA and parental means was found. The efficiency of water use under stress did not correlate with stress tolerance indices, but stress-induced changes in the harvest index and WUE were closely related to the tolerance. An analysis of genetic components of variation indicated that additive gene effects were of major importance for the vegetative and economic WUE measures. Moderately high narrow-sense heritabilities of WUE under optimal conditions (0.64-0.69) were found to decrease to 0.46-0.53 and 0.13-0.35 under limited fertilization and simulated drought, respectively. Partial dominance of genes was observed. The degree of dominance of genes was found to increase under stress. The results suggest that a low WUE is a recessive character. It is supposed that the preponderance of additive gene effects should facilitate selection efforts to improve WUE in spring barley.

The review describes practical methods of the use of edible fungi: Boletus spp. and Morchella spp. The cultivation of fruit bodies of Morchella esculenta is complicated and unprofitable. During last years, the significance of submerged liquid culture has increased. Harvested biomass contains mushroom aroma compounds and good chemical composition (protein, polysaccharides, vitamins and mineral elements). The composition of mushrooms suggests two medicinal properties: nutritional benefit as food supplement and therapeutic advantages. Mushroom powder can be used as appendix to soups and sauces or in animal feed industry. Mushrooms and their products are important for their flavour, medicinal properties, ecological and economical values.

Effects of high and reduced NPK nutrition on the genetic variation of components of water use efficiency at the leaf and whole-plant levels were examined in pot-grown old and modern cultivars of winter wheat (Triticum aestivum L.). At the subsequent growth stages, the photosynthetic rate (A), transpiration rate (E), leaf area (LA) and gas exchange efficiency (A/E) were measured on fully developed 4th, 5th, penultimate and flag leaves. At the plant canopy level, the total amount of water transpired was recorded during the whole life cycle to determine the efficiency of water use in the vegetative (WUEveg) and grain (WUEgen) matter formation. Considerable genotypic differences were found for the characters studied. The limited NPK supply caused a decrease in LA, A and A/E, but contributed to an increase in WUEgen. Examined cultivars (C) did not interact with nutrition levels (N) for these characteristics. However, the position of leaves (L) and the C ? L and N ? L interactions significantly affected the variance in leaf photosynthetic characteristics. A and A/E were negatively correlated with LA, and the flag leaves were photosynthetically less active and less efficient per unit area than the lower leaves. The whole-plant components of WUE were found to be more genetically stable than the photosynthetic leaf characteristics. Some modern cultivars tended to form leaves of higher A and A/E than the older ones, and this corresponds with a more efficient use of water in grain formation (WUEgen) of the former. Stay-green duration of flag leaves and harvest index showed positive correlations with WUEgen. However, no close associations were noticed between WUE components and stress tolerance, and the modern cultivars were usually less tolerant to NPK shortage.
