QTL mapping of root traits in wheat under different phosphorus levels using hydroponic culture

tailieu.vn

Therefore, optimization of root and biomass related attributes such as root length, root width, root tips number, root diameter, root biomass and shoot biomass at seedling stage could provide a promising avenue to explore early variations correlated with high P uptake. Genetic diversity for root-related traits under different nutrient conditions has been also considered very important for grain yield enhancement [5, 6].

Springer Old Growth Forests - Chapter 10

Where data on fine root biomass from the literature have been compiled, such analyses do not reveal clear temporal patterns of fine root biomass with stand age, and even show contradictory trends for different species. In their analysis of published studies, Leuschner and Hertel (2003) showed that the fine root biomass of Fagus sylvatica appeared to decline with age, whereas fine root biomass in Picea abies stands increased with stand age..

QTL mapping of seedling root traits in Synthetic W7984 × Opata M85 bread wheat (Triticum aestivum L.) mapping population

tailieu.vn

Overlapping loci for seedling and mature root traits To find seedling and maturity interactions for root and shoot traits, data obtained in this study was reanalyzed with root and shoot biomass data from Bektas et al. Previous studies suggest that QTL for related traits is often colocated in close proximity (Tuberosa et al., 2002. Zhang et al., 2013a). Several loci on chromosome 2A were previously reported for root biomass and distribution (deep root ratio) (Ehdaie et al., 2016.

Studying and Evaluating the Ability to form Carbon Sinks in Biomass of the Pure Sonneratia caseolaris Plantation in the Coastal Area of Tien Lang district, Hai Phong city

tailieu.vn

Therefore, the 10-year-old stand had a higher content of carbon in below-ground biomass than the 11 and 13 year-old stands. this could be explained that the 10-year-old trees are. in the stage of growth and development. The 13-year-old trees started showing signs of slower growth, so the carbon content in root biomass was lower than that of trees aged 10 and 11 years..

Effect of potassium application in drought-stressed tobacco (Nicotiana rustica L.) plants: Comparison of root with foliar application

In this work, application of K restored root growth of both well-watered and drought-stressed plants suggesting an important role for K in the production of root biomass and surface area and determination of the ability for water and nutrients uptake particularly under drought conditions.

Temporal variability of the macroinvertebrate community associated with Eichhornia azurea (Swarts) Kunth (Pontederiaceae) in a lake marginal to a tropical river

tailieu.vn

This probably occurred in July in Barbosa Lake, since the high root biomass value and low macroinvertebrate density associated with the extraordinary flooding led to a great reduction in density in the following months. Another factor that can affect community density is root complexity, but it was not measured in the present study.. Studies on plant decomposition also showed a negative relationship between an increase in density and a decrease in root biomass (Mormul et al., 2006.

Characterization of genotypic variability associated to the phosphorus bioavailability in peanut (Arachis hypogaea L.)

tailieu.vn

Our work shows genotypic variation in biomass production according to the nodulation and TCP addition. Shoot biomass was increased for all peanut genotypes after inoculation or TCP addi- tion. These results are in agreement with those acquired by other studies in similar conditions (Taurian et al., 2010). However, a reduction of root biomass was observed when genotypes were cul- tivated on TCP conditions which in the lowest root biomass were registered. (Stryker et al., 1974), Zea mays L.

Mapping and validation of a major QTL for primary root length of soybean seedlings grown in hydroponic conditions

tailieu.vn

Moreover, no QTL of total root biomass was detected in the qRL16.1 region. The validation of the re- lationship between qRL16.1 and Glyma16.141800 will enable us to understand the mechanism of primary root and lateral root development.. [31] demonstrated that the alteration of the root system architecture improved drought avoidance using DRO1, a rice QTL controlling the root growth angle.

A review of cunninghamia lanceolata (Lamb.) Hook: A recent update and potential application in Vietnam

Similarly, another study showed that the fine root biomass of trees and understory vegetation were significantly and negatively correlated with forest biomass, but the results clearly demonstrated that fine tree root biomass was significantly promoted and increased due to competition from understory vegetation where forest biomass is low (Liao et al., 2019).. lanceolata forests (Yang et al., 2019).

As a global average, over 60% of the root biomass is found in the top 20 cm of the soil (Fig. The gradient in soil carbon is much smaller. 10 by Bauhus, this volume) and might therefore only indirectly influence soil carbon accumulation.

Plant diversity and local rainfall regime mediate soil ecosystem functions in tropical forests of north-east Bangladesh

Rainfall also increases soil microbial habitat and activ- ity of soil micro-organisms by positively influencing plant root biomass ( Taylor et al., 2017 . Sun et al., 2016. washout the sand particles in topsoil through erosion that can negatively affect the soil aggregate stability ( Huang et al. Hammad et al., 2006. Correlation coefficient ( r ) matrix between species richness, abundance and bioclimatic variables with indicators of soil ecosystem functions in our study.. et al.

Study on the accumulation of copper from soil to biomass of some vegetables

tailieu.vn

Among these plants, lettuce has the accumulative capacity of metals inside its parts at a relatively high rate, which increases in the root and gradually decreases during the translocation to the shoot (Peijnenburg, Fang, Shu, &. The similar comment was proposed from the analytical results of copper accumulated in spinach biomass. On average, the copper content in root was 1.5 times higher than that in shoot of this plant.
