Biomass materials have received attention for energy storagebecaused of the advantage of low-cost, easy-to-prepare, and eco-friendliness. Three-dimensional carbon materialswith abundant pore structure gradually becomeresearch hotspot in high-performance energy storage. In this study, an easy-to-prepare, green, light and elastic activated carbon was present using the biomass Juncus effusus (JCE)...

Treatment of the eggs of the sea urchin with a 1 M solution of glycerol at fertilization allows the recovery from this solution of the protein released from the cortical granules, including that which would normally give rise to the hyaline layer. The calcium-gelable protein previously extracted from whole eggs and from isolated cortical material was found to be present in the glycerol solution...

Jelen tanulmány a Magyarország délkeleti részén fekvő Körös-vidék nyílt sziki tölgyeseinek (Galatello-Quercetum roboris) társulási viszonyait mutatja be 25 cönológiai felvétel alapján. A tölgy-kőris-szil ligetek (Fraxino pannonicae-Ulmetum) fokozatos kiszáradásával előbb zárt tölgyesek (Melico altissimae-Quercetum roboris), majd szikesedési folyamat további előrehaladtával jönnek létre. Az átal...

The mating system of a plant is the prime determinant of its population genetic structure. However, mating system effects may be modified by postzygotic mechanisms like inbreeding depression. Furthermore, historical as well as contemporary ecological factors and population characteristics, like the location within the species range can contribute to genetic variability. Using microsatellite mar...

Flooded plant roots commonly form aerenchyma, which allows gas diffusion between shoots and roots. The programmed cell death involved in this induced aerenchyma formation is controlled by the plant hormone ethylene, as has been shown for maize (Zea mays). However, the role of ethylene is uncertain in wetland species that form constitutive aerenchyma (also under nonflooded conditions). The aim o...

soil and rates of radial oxygen loss. Radial O2 loss is in turn influenced by plant activity (Bedford et al., 1991; Iron (III) plaque forms on the roots of wetland plants from the Kuehn and Suberkropp, 1998) and morphological charreaction of Fe(II) with O2 released by roots. Recent laboratory studies acteristics such as suberized and lignified roots (Armhave shown that Fe plaque is more rapidly...
