Interspecific Differences of the Root System Structures of Four Cereal Species as Affected by Soil Compaction
Cereal root system structures Interspecific differences Lateral root development Mechanical impedance Root system morphometry Root extension rate Soil compaction Soil physical environment
2009/8/5
Comparison of the root system structures of four cereal species as affected by soil compaction was conducted morphometrically. Plants were grown under two different soil bulk densities of 1.33g/cm3 (c...
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...
Applicable Range of the Pipe Model to the Structure of Soybean (Glycine max Merr.) Root System
Glycine max Merr Pipe model Plow sole depth Root diameter Root system Soybean
2009/7/30
The applicability of the pipe model to the structure of soybean (Glycine max Merr.) root system grown under various underground water levels or depths of plow sole were investigated. The form, distrib...
Analysis of Timecourse Changes in Root System Morphology of Rice in Excised Root Culture
Excised root culture Fractal Oryza sativa L Rice Root system development Timecourse change
2009/7/29
The development of cultured seminal root system of rice was analyzed to determine the most appropriate culture period for the characterization of root system morphology. Excised seminal root tips of T...
Carbon and Nitrogen Dynamics with Aging in Seminal Root System of Rice Seedling
Aging Carbon Lateral roots Nitrogen Partitioning
2009/7/29
The allocation pattern of carbon (C) and nitrogen (N) with aging among several organs of rice seedling was investigated with particular attention to the difference in seminal root axis (SRA) and conco...

Fiber-optic scope Minirhizotron Root length Root length density Root system Soil-core sampling metho
2009/7/28
In order to develop a simple and accurate system for measuring the root system of soybean plants growing in the field, a fiber-optic scope with a portable color video tape recorder was employed in a ...
Analysis on Root System Morphology in Rice with Reference to Varietal Differences at Ripening Stage
Nodal roots 0ryza sativa L Root depth index Root distribution Root length Root weight
2009/7/28
The morphology of the rice root system was established by analyzing varietal differences. Four rice varieties, Koshihikari, Dobashi 1, IR36 and Lemont, were grown in an experimental paddy under ordina...
Changes with Aging of Endogenous Abscisic Acid and Zeatin Riboside in the Root System of Rice
Abscisic acid Aging Enzyme immunoassay Lateral roots Oryza sativa L Seminal root system
2009/7/28
Plant roots produce abscisic acid (ABA) and zeatin riboside (ZR) which are known to counteract the aging of plant organs. Changes in ABA and ZR levels were determined by an enzyme immunoassay method i...
Modification of Root System Morphology in a Peanut Seedling Inoculated with Arbuscular Mycorrhizal Fungus, Gigaspora margarita Becker & Hall
Arachis hypogaea L Arbuscular mycorrhiza Gigaspora margarita Becker & Hall Lateral root Peanut
2009/7/27
Modification of root system morphology caused by the inoculation of arbuscular mycorrhizal fungus (Gigaspora margarita Becker & Hall) was evaluated in peanut (Arachis hypogaea L.). Peanut plants were ...
Genotypic Variation in the Development of Seminal Root System of Rice under Different Culture Conditions in vitro
Genotypic variation in vitro Lateral root Link length Oryza sativa L
