licorice, glycyrrhiza glabra (fabaceae), is one of the herbal medicines. glycyrrhizin is the importance content through compounds exiting in licorice, which is 50 times sweeter than sucrose. glycyrrhizin used as the primary matter in pharmacy and used to remedy of many diseases, and also, used in tobacco, confectionary and beverage industries. since glycyrrhizin in the phases of growth received...

Plant contributions to the nitrogen (N) cycle from decomposition are likely to be altered by vegetation shifts associated with climate change. Roots account for the majority of soil organic matter input from vegetation, but little is known about differences between vegetation types in their root contributions to nutrient cycling. Here, we examine the potential contribution of fine roots to the ...

The ability to predict the spatial distribution of tree root system variables (e.g., Root Area (RA), maximum diameter, number roots in diameter classes, density fine roots, etc.) under different environmental conditions is relevant several scientific disciplines and engineering practice. In this work, three well known analytical models from literature are assembled into a unique framework calle...

Two different propagation procedures including aeroponics and soil systems were compared for the minitubers production in potato. The minitubers were evaluated for several quality characters. The plant materials were from three cultivars, Agria, Marfona and Savalan. The plantlets were grown in aeroponics and soil production systems at a plant density of 100 plants per m-2 and stem length, root ...

Characterizing plant functional diversity is essential to decipher community assembly rules and ecosystem functioning. Most studies focused on above-ground traits whereas the analysis of root lags far behind. We analyzed structure fine (< 2 mm) diameter distribution at level as an indicator morphological diversity, hypothesized that shape provide insights types exploration strategies. tested th...

The objectives of this study were to detect coarse tree root and to estimate root biomass in the field by using an advanced 3D Ground Penetrating Radar (3D GPR) system. This study obtained full-resolution 3D imaging results of tree root system using 500 MHz and 800 MHz bow-tie antennas, respectively. The measurement site included two larch trees, and one of them was excavated after GPR measurem...

Fine-root systems represent a very sensitive plant compartment to environmental changes. Gaining further knowledge about their dynamics would improve soil carbon input understanding. This paper investigates C and N concentrations in fine roots in relation to different stand characteristics resulting from conversion of coppiced forests to high forests. In order to evaluate possible interferences...
