To better understand the complex mechanisms of action of earthworms on plants, we set up an experimental system using the model plant Arabidopsis thaliana (L.) Heynh, Aporrectodea caliginosa a common temperate earthworm and two types of soil with contrasted contents in organic matter and nutrients. Changes in plant biomass, biomass allocation to roots, leaves and stems and C/N ratios were relat...

This study aimed to test the hypothesis that root morphology might be improved and consequently contributing to superior post-heading shoot growth and grain yield in late-stage vigor super rice. A pot experiment was carried out to compare yield attributes, shoot growth and physiological properties and root morphological traits between a late-stage vigor super rice cultivar (Y-liangyou 087) and ...

climate change due to increasing the level of greenhouse gases including co2 is the main environmental issue of the world in the new century. one of the effective way for reducing atmospheric co2 is carbon sequestration by plants and soils. a vast area of iran has desert condition with special adapted plant species in which can be devoted for carbon sequestration. hammada salicornica as a shrub...

1. Introduction The evaluation of tree root biomass is significant and difficult to survey accurately. Traditional approach used for roots biomass harvest (e.g., soil cores and trenches) provide reasonable accurate information but they are destructive in nature, labour intensive, and limited whit respect to soil volume and surface area that can be assessed. Data derived from traditional root ex...

Applications of unmanned aircraft systems (UASs) to assist in forest inventories have provided promising results in biomass estimation for different forest types. Recent studies demonstrating use of different types of remotely sensed data to assist in biomass estimation have shown that accuracy and precision of estimates are influenced by the size of field sample plots used to obtain reference ...

Goldenseal (Hydrastis canadensis L.) is used to combat inflammation and infection. Its antibacterial activity in vitRO has been attributed to its alkaloids, the most abundant of which is berberine. The goal of these studies was to compare the composition, antibacterial activity, and efflux pump inhibitory activity of ethanolic extracts prepared from roots and aerial portions of H. canadensis. E...

In order to understand plant functioning, plant community composition, and terrestrial biogeochemistry, it is decisive to study standing root biomass, (fine) root dynamics, and interactions belowground. While most plant taxa can be identified by visual criteria aboveground, roots show less distinctive features. Furthermore, root systems of neighboring plants are rarely spatially segregated; thu...

Plant growth and productivity are often limited by high root-zone temperatures (RZT) which restricts the growth of subtropical and temperate crops in the tropics. High RZT temperature coupled with low growth irradiances during cloudy days which mainly lead to poor root development and thus causes negative impact on the mineral uptake and assimilation. However, certain subtropical and temperate ...

given the potential for carbon storage in plant tissues, this approach has a serious interest in recent decades. therefore, the ability of carbon storage in astragalus gossypinus and astragalus parrowianus were examined in part of alpine pastures in kermanshah province. after determining the representative districts, according to 4 main aspect and 5 category elevation was determined representat...
