Paper birch (Betula papyrifera Marsh) seedlings were grown in a greenhouse in either subsoil or topsoil in factorial combination with two fertilization and drought regimes to investigate how different soil environments and nutrient availability drive belowground partitioning between growth, secondary metabolism and ectomycorrhizal (EM) associations, and impact drought tolerance of paper birch. ...

Root systems serve important roles in carbon (C) storage and resource acquisition required for the increased photosynthesis expected in CO2-enriched atmospheres. For these reasons, understanding the changes in size, distribution and tissue chemistry of roots is central to predicting the ability of forests to capture anthropogenic CO2. We sampled 8000 cm(3) soil monoliths in a pine forest expose...

Gerbera jamesoniiis of commercial significance and fifth most used cut flower in the world today. A pot experiment was performed to see the effect of co-inoculation of arbuscular mycorrhizal fungi (AMF) i.e. (Glomus mosseae andAcaulospora laevis) with phosphate solubilizing bacteria Pseudomonas fluorescensin the presence of different doses of superphosphate (low, medium, high) on growth establi...

Climate change is one of the most important challenges in sustainable development which has negative effect on terrestrial and aquatic ecosystem. The lead factor of this phenomenon is Co2 accumulation in atmosphere. One of the suitable ways of facing the mentioned issue is carbon sequestration in plant biomass and soil as a simple as well as inexpensive refined way in rangelands. With respect t...

Aerial roots in Rhizophora rise from stems, branches, and secondarily thickened, anchored, aerial roots, but only after injury from unanchored aerial roots. Lateral subterranean roots are abundantly developed upon penetration of a mud substrate whereupon the histology of the root undergoes marked and abrupt changes so that chlorophyll is no longer developed, trichosclereids no longer differenti...

two glasshouse and field experiments were conducted to assess the effects of root system, water uptake, water use efficiency and early vigor on yield and drought tolerance of bread wheat in two successive farming seasons (2009-11). the experiments were conducted as randomized complete block design and two-year results analyzed as combined design. considerable genetic variation was observed amon...

Genetic modification of shoot and root morphology has potential to improve water and nutrient uptake of wheat crops in rainfed environments. Near-isogenic lines (NILs) varying for a tillering inhibition (tin) gene and representing multiple genetic backgrounds were phenotyped in contrasting, controlled environments for shoot and root growth. Leaf area, shoot and root biomass were similar until t...

Optical remote sensing data have been considered to display signal saturation phenomena in regions of high aboveground biomass (AGB) and multi-storied forest canopies. However, some recent studies using texture indices derived from optical remote sensing data via the Fourier-based textural ordination (FOTO) approach have provided promising results without saturation problems for some tropical f...
