Varietal Differences in Geotropic Response of Primary Seminal Root in Japanese Wheat
Agar medium Geotropic responses Primary seminal root Triticum aestivum
2009/8/6
Growth angles of inclination of primary seminal roots for 133 Japanese wheat varieties were examined in an agar medium. Germinated seeds were set on a 0.2% agar medium and the initial emergence direct...

2009/7/30
The development of rice root system has been studied in Japonica-Indica hybrid cultivars (J-IH), Milyang 23 and Suweon 264, and Japonica type cultivars (JT), Nipponbare and Koshihikari, grown in a pad...
Studies on Direct Sowing Culture of Rice in Northern Kyushu : II. Evaluation of lodging tolerance by crown root thickness during seedling stage
Crown root thickness Direct sowing culture Lodging tolerance Northern Kyushu Rice Seedling stage
2009/7/27
This study was undertaken to find a method of evaluating lodging tolerance under direct sowing culture in flooded paddy field by the crown root thickness of seedlings for the selection of good eating ...
Development of Root System in Rice Based on Formation of Phytomers : An analysis on varietal difference in root length and weight in a pot experiment
Nodal roots Oryza sativa L Phytomer Rice Root length Root system
2009/7/22
Because the framework of a root system in rice consists of nodal roots which emerge from the stem part of the phytomers, the number and size of the phytomers could affect the morphology of the root s...
Stability of Phenotypic Variation of Root Length over Environmental Conditions in the Seedling Generation of Potato
Breeding Day length Root length Seedling generation Selection Soil water
