Root Growth and Partitioning of 13C-labelled Photosynthate in the Seminal Root of Corn Seedlings as Affected by Light Intensity
Carbon partitioning Light intensity Root growrth Root system Zea mays L.
2009/8/4
The effects of shading on growth and allocation pattern of photosynthate in the seminal root of corn seedlings were studied using 13C as a tracer. Corn seedlings, preshaded for 2 days (light intensity...
Effect of Water Potential of Culture Medium on Geotropic Response of Primary Seminal Root in Japanese Wheat Cultivars
Geotropic response Primary seminal root Triticum aestivum Water potential
2009/8/4
It has been observed that wheat has a shallow root system in wet soil and a deep root system in dry soil. However, the control mechanisms of root growth depending on soil water status remain unclear. ...
Root Branching in Maize:I. "Branching index" and methods for measuring root length
Branch root Branching index Image analyzing system Line intersection method Maize
2009/8/4
Root branching in maize (Zea mays L. cv. Pioneer 3558) at harvest stage was examined, with the "branching index" defined as the product of the 'length factor' and 'density factor'. "Branching index" w...
Influence of Planting Density on Root Growth and Yield in Potato
Canopy structure LAI Root distribution Root length Root length density Solanum tuberosum L
2009/8/4
The influence of planting density on root growth and its relationship to leaf and tuber growth were investigated with two maincrop varieties in the potato. Three levels of planting density were exami...
Relationship between Root Growth Angle of Seedlings and Vertical Distribution of Roots in the Field in Wheat Cultivars
Cultivar Root Root depth index (RDI) Root growth angle Seminal root Vertical distribution of roots
2009/8/4
Vertical distribution of roots is known to influence environmental stress tolerance of crops. To estimate the genotypic characteristic on the vertical distribution of roots in the field, the growth an...

This study was conducted to examine whether the root system development in rice plant under different nitrogen (N) application regimes is related to adaptability for heavy manuring (AHM) of the cultiv...
Response of the Seminal Root Elongation to NH4-Nitrogen in Several Rice Cultivars
Adaptability Heavy manuring NH4-nitrogen Rice Root elongation Seminal root
2009/8/4
The aim of this study was to examine the effect of various NH4-nitrogen concentrations in culture solution on the seminal root elongation of the rice plant. Ten rice cultivars with differing adaptabil...
Heterosis for Root System Development in Japonica/Indica F1 Rice Hybrid
Heterosis Japonica/indica F1 hybrid Lateral root Nodal root Rice Specific root length Total root length
2009/8/4
Vigorous growth of F1 hybrid of rice (Oryza sativa L.) may be partially attributed to the development and function of the root system, but only a few studies have been conducted in this aspect. This s...
