Role of root and yield characters under drought stress in rice (Oryza sativa L.) [PDF]

open access: yesElectronic Journal of Plant Breeding, 2014
Drought is the major constraint to rice production and yield stability in rainfed areas. Association analysis was performed in F1 generation of rice in order to understand the nature and extent of association among various traits and grain yield under ...

A comparison between water uptake and root length density in winter wheat: effects of root density and rhizosphere properties [PDF]

open access: yes, 2020
© 2020, The Author(s). Background and aims: We aim to quantify the variation in root distribution in a set of 35 experimental wheat lines. We also compared the effect of variation in hydraulic properties of the rhizosphere on water uptake by roots ...

Shaping of molecular weight distribution using b-spline based predictive probability density function control [PDF]

open access: yes, 2004
Issues of modelling and control of molecular weight distributions (MWDs) of polymerization products have been studied under the recently developed framework of stochastic distribution control, where the purpose is to design the required control inputs ...

Pathogenicity of the root-knot nematode Meloidogyne javanica on potato [PDF]

open access: yes, 2005
Host–parasite relationships and pathogenicity of Meloidogyne javanica on potatoes (newly recorded from Malta) were studied under glasshouse and natural conditions. Potato cvs Cara and Spunta showed a typical susceptible reaction to M. javanica under

Modelling diverse root density dynamics and deep nitrogen uptake — a simple approach [PDF]

open access: yes, 2009
We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page in J Appl Ecol 11:773–781, (1974). A

The effect of the soil compaction on the contents of alfalfa root reserve nutrients in relation to the stand density and the amount of root biomass

open access: yesSoil and Water Research, 2007
The reserve root nutrients influence the overwintering, regrowth, yield, and persistence of alfalfa plants. The total amount of the root reserves is considered more important than their concentration.

Dietary Energy Density in Relation to Subsequent Changes of Weight and Waist Circumference in European Men and Women [PDF]

open access: yes, 2009
Background - Experimental studies show that a reduction in dietary energy density (ED) is associated with reduced energy intake and body weight.

Different Responses in Root Water Uptake of Summer Maize to Planting Density and Nitrogen Fertilization [PDF]

open access: yes, 2022
Modifying farming practices combined with breeding has the potential to improve water and nutrient use efficiency by regulating root growth, but achieving this goal requires phenotyping the roots, including their architecture and ability to take up water

The metabolic inter-relationships between changes in waist circumference, triglycerides, insulin sensitivity and small, dense low-density lipoprotein particles with acute weight loss in clinically obese children and adolescents. [PDF]

open access: yes, 2014
OBJECTIVE: Small, dense low-density lipoprotein (LDL) particles are highly atherogenic and strongly associated with obesity-related dyslipidemia. The metabolic inter-relationships between weight loss induced changes in waist circumference, triglycerides,

Root Growth, Water and Nitrogen Use Efficiencies in Winter Wheat Under Different Irrigation and Nitrogen Regimes in North China Plain

open access: yesFrontiers in Plant Science, 2018
Excessive nitrogen (N) application combined with water shortage has a negative effect on crop production, particularly wheat (Triticum aestivum L.) production in the North China Plain.
