Zinc chemical forms and organic acid exudation in non-heading Chinese cabbages under zinc stress
Non-Heading Chinese Cabbages Zn Stress Chemical Forms Root Exudation
2013/2/28
As an essential element, zinc also is a heavy metal. Non-heading Chinese cabbage showed obvious tolerance to Zn stress in former research. To further understand the mechanisms involved in Zn adaptabil...
Developing Isogenic Lines of Japanese Rice Cultivar ‘Koshihikari’ with Early and Late Heading
heading date marker-assisted selection pleiotropic effect quantitative trait locus
2011/2/24
Four quantitative trait loci (QTLs) for rice (Oryza sativa L.) heading date were previously detected by QTL analysis of progeny derived from crosses between a japonica cultivar, Koshihikari, and an in...
Thermo-sensitivity and Photoperiod Sensitivity Genes Controlling Heading Time and Flower Bud Initiation in Sorghum, Sorghum bicolor Moench
AFLP complementary gene effect daylength heading response inheritance
2011/2/24
The timing of heading and flower bud initiation is critical for reproductive success. In sorghum (Sorghum bicolor Moench), which is a facultative short-day plant, we propose that the thermo-sensitivit...
Two Distinct Growth Types for Number of Developed Leaves, Heading Time, Culm and Panicle Lengths, and Internode Length within Near-isogenic Lines of Rice
breeding cultivation uniformity
2009/9/9
There are two growth types of plants for the number of developed leaves, heading time, and culm and panicle lengths within a population of a homozygous rice cultivar. However, this phenomenon has not ...
The Effect of Temperature and Daylength on Heading in Diploid Rhodesgrass Cultivars
days to heading flower initiation photoperiod sensitivity
2009/9/9
The present study was conducted to clarify the effect of temperature and daylength on heading in diploid rhodesgrass cultivars. Three diploid cultivars, Tochiraku-kei, Fords-Katambora and Pioneer, wer...
Physico-ecological Studies on Quality Formation of Rice Kernel:I. Effects of nitrogen top-dressed at full heading time and air temperature during ripening period on quality of rice kernel
Amylose Eating quality Fat-by-hydrolysis Nitrogen top-dressed Protein Rice
2009/8/6
Effects of nitrogen top-dressed at full heading time and air temperature during ripening period on rice quality were investigated from the viewpoints of the texture of cooked rice and protein, amylose...
Appearance and Heading of Tillers in Early Wheat Cultivars of West Japan
Early maturing cultivar Heading Tiller appearance Varietal difference Wheat
2009/8/6
Three early wheat cultivars of west Japan, Norin 26, Norin 61 and Omasekomugi, sown in autumn, were compared regarding tiller appearance and heading. The difference in maximum tiller number among thre...
Flag Leaf Number Determination of Secondary and Tertiary Tillers and Heading Characteristics of Rice Plants
Flag leaf number Heading date Main culm Rice plant Sheath wrapping Tillers
2009/8/6
When the number of leaves on the main culm is known, the number of leaves on secondary to quarternary tillers can be determined based on the following growth characteristics and procedures, even if th...
Characteristics Relating Young Panicle Development and Heading of Closely Related Calrose Rice Genotypes
Distance between collars Heading date Leaf number index Main culm Tillers panicle
2009/8/6
Seven near-isogenic lines which were derived from rice cultivar "Calrose" were sown on June 8, 1985, and transplanted on June 25 at the fourth leaf stage in rice facility of the University of Californ...
Changes of Heading Time and Panicle Weight in Rice Subjected to Water Stress during the Early Stage of Panicle Development
Cumulative water stress Heading time Leaf water potential Panicle weight Rice
2009/8/6
The increase of heading time in proportion to cumulative water stress (an integrated estimate of the degree and duration of water stress) was demonstrated in a wetland rice cultivar Koshihikari subjec...
Sterile Spikelets of Rice Plants Induced by Low Temperature in 1988:Difference in heading date among stems and spikelet locations on the panicle
