Black locust under drought stress

Effects of drought frequency on growth performance and transpiration of young black locust (Robinia pseudoacacia L.) Black locust (Robinia pseudoacacia L.) is a drought-tolerant fast growing tree, which could be an alternative to the more common tree species used in short-rotation coppice on marginal land. The plasticity of black locust in the form of ecophysiological …

Formation of biocrusts at reclaimed post-mining sites

Formation of soil lichen crusts at reclaimed post-mining sites, Lower Lusatia, North-east Germany Soil lichen communities can be found in many open landscapes in Europe where the soil surface is free of higher vegetation or with a sparse cover as xerothermic steppes, heaths or coastal and inland dunes . Such biological soil communities are built …

Water use of the new bioenergy crop Igniscum

 Transpiration and biomass production of the bioenergy crop Giant Knotweed IGNISCUM under various supplies of water and nutrients. Soil water availability, nutrient supply and climatic conditions are key factors for plant production. For a sustainable integration of bioenergy plants into agricultural systems, detailed studies on their water uses and growth performances are needed. The new …

Impact of drought stress on black locust – a lysimeter experiment

Black locust (Robinia pseudoacacia L.) ecophysiological and morphological adaptations to drought and their consequence on biomass production and water use efficiency The response of black locust (Robinia pseudoacacia L.) to water limitation was investigated in a lysimeter experiment. Plants were grown under three different soil moisture regimes, with values set at 35%, 70%, and 100% …

How halophytes influencing their parasites ?

Influence of halophytic hosts on their parasites – the case of Plicosepalus acaciae Halophytes develop various morphological and physiological traits that enable them to grow successfully on saline substrates. Parasitic plants on halophytic hosts may also encounter salt stress. We investigated the mistletoe Plicosepalus acaciae (syn: Loranthus acacia; Loranthaceae), which occurs on five halophytic and …

Biocrusts on reclaimed post-mining sites

Synergic feedback mechanisms control generation of surface patchiness on tertiary sands in a minesite recultivation area covered with biological soil crusts In a recultivation area located in Brandenburg, Germany, five types of biocrusts (initial BSC1, developed BSC2 and BSC3, mosses, lichens) and non-crusted mineral substrate were sampled on tertiary sand deposited in 1985– 1986 to …
