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 promoter from SlREO, a highly-expressed, root-specific Solanum lycopersicum gene, directs expression to cortex of mature roots [PDF]

open access: yes, 2008
Root-specific promoters are valuable tools for targeting transgene expression, but many of those already described have limitations to their general applicability.

In situ Root Phenotypes of Cotton Seedlings Under Phosphorus Stress Revealed Through RhizoPot

open access: yesFrontiers in Plant Science, 2021
Phosphorus (P) deficiency is a common challenge in crop production because of its poor mobility through the soil. The root system plays a significant role in P absorption from the soil and is the initial indicator of low P levels. However, the phenotypic

EVALUATION OF PHYSIOLOGICAL SEED QUALITY AND FIELD PERFORMANCE FOR DIFFERENT TYPES OF MAIZE HYBRIDS [PDF]

open access: yesمجلة الأنبار للعلوم الزراعية
Farmers use seeds with good vigor as they guarantee a higher rate of emergence compared to less robust varieties to avoid replanting and the resulting delay in maturity or lower productivity due to poor plant density, caused mainly by their genetic ...

Corn root morphoanatomy at different development stages and yield under water stress [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2016
: The objective of this work was to characterize the morphoanatomy of roots and the yield traits of two corn hybrids contrasting for drought tolerance (DKB 390, tolerant; and BRS 1030, sensitive), at different stages of development.

Changes of Root Length and Root-to-Crown Ratio after Apical Surgery: An Analysis by Using Cone-beam Computed Tomography [PDF]

open access: yes, 2015
INTRODUCTION Apical surgery is an important treatment option for teeth with post-treatment periodontitis. Although apical surgery involves root-end resection, no morphometric data are yet available about root-end resection and its impact on the root ...

Morphology of the coffee root system using polyethylene film

open access: yesRevista Ceres, 2023
In the initial phase of the coffee crop, the control of weeds and water availability for the establishment of the plants is a concern. The polyethylene cover can positively influence the chemical and biological characteristics of the soil and ...
