2009/8/6
The relationship between fructan (fructose polymer) level in early winter and overwintering ability in wheat varieties was studied by using 15 varieties and 14 lines related to pedigree of breeding. 1...
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...

Evaporative demand Grain yield Leaf water potential Location Radiation Spikelet number
2009/7/31
We observed previously (Part 1) that maintenance ability of leaf water potential (Ψ1) in rice plants under paddy field conditions changed depending on planting years and seasons and individual locatio...
Relationship between Leaf Movement of Trifoliolate Compound Leaf and Environmental Factors in the Soybean Canopy : II. Effects of growth and environmental conditions on diurnal changes of leaf movement
Diurnal change Growth stage Heliotropic leaf movement Leaf inclination angle Leaf position Soil water deficit Soybean Trifoliolate compound leaf
2009/7/30
We previously reported a method for measuring trifoliolate compound leaf movement in the soybean plant. Leaflet movement was investigated by measuring the area of triangle described by the three leafl...
