Most water and essential soil nutrient uptake is carried out by fine roots in plants. It is therefore important to understand the global geographic patterns of fine-root nitrogen and phosphorus cycling. Here, by compiling plant root data from 211 studies in 51 countries, we show that live fine roots have low nitrogen (N) and phosphorus (P), but similar N:P ratios when compared with green leaves...

Xylem hydraulic safety and efficiency are key traits determining tree fitness in a warmer drier world. While numerous plant studies have focused on branches, our understanding of root functioning remains limited, although roots control water uptake, influence stomatal regulation commonly been considered as the most vulnerable organ along pathway. We investigated 11 related to xylem pathway four...

The ability of roots to penetrate hard soil is important for crop productivity but specific root phenes contributing to this ability are poorly understood. Root penetrability and biomechanical properties are likely to vary in the root system dependent on anatomical structure. No information is available to date on the influence of root anatomical phenes on root penetrability and biomechanics. R...

abiotic stresses and lack of nutrients are one of the most important factors in reducing the crop yield.  vigorous and developed roots can facilitate uptake of water and nutrients more efficiently making it essential for enhancing the yield. association mapping is currently one of the approaches for detecting quantitative trait loci (qtls) influencing complex traits. this approach was used to d...

Quantifying the soil reinforcement provided by roots is essential for assessing contribution of forests to reducing shallow landslide susceptibility. Many soil-root models were developed in literature: from standard single root model fibre bundle model. The input parameters all are geometry (diameter and length) biomechanical properties (maximum tensile force elastic modulus). This study aims i...

Seed is a basic component of every crop species and quality seed essential for farmers to achieve greater production higher yields. yield can be improved by using the growth hormones. Indole-3-butyric acid (IBA) IBAplays vital role in reproductive development plant. An investigation being conducted determine effect rooting hormone IBA on that leads developement. Roots treated with three levels ...

To understand soil colonization by a root system, information is needed on the architecture of the root system. In monocotyledons, soil exploration is mainly due to the growth of adventitious primary roots. Primary root emergence in banana was quantified in relation to shoot and corm development. Root emergence kinetics were closely related to the development of aerial organs. Root position at ...

Recently, a lnorthern red oak tree was found on the Bent Creek Experimental Forest, Buncombe County, North Carolina, with an unusual and interesting group of aerial roots originating from the callused area surrounding an old wound. This tree, shown in the accompanying photograph, is about 100 feet high, has approximately 3 log lengths and is 33.5 inches in diameter at 4.5 feet above the ground....

Apple leaf characteristics are the most important vegetative growth and development traits. The apple rhizosphere is also indirectly responsible for development. It provides roots with elements compounds that improve roots’ shoots’ application of exogenous plant regulators such as strigolactones (SLs) has become one main trends improving enhancing microbiome. This study aimed to investigate eff...
