2009/7/22
Japonica type rice line 9004, high yielding glutinous rice developed in Jiangsu Province, China, was cultivated with and without nitrogen at early tillering (ETS), spikelet differentiation (PFS I), s...
Some Limiting Factors and Improvement for the Overwintering Ability of Spring Wheat Sown before Continuous Snow Cover(Crop Physiology and Cell Biology)
Germination Overwintering ability Seed Seed nutrient Snow mold Sowing before continuous snow cover
2009/7/15
It has been known that spring wheat sown immediately before continuous snow cover has higher quality and yield than that sown in spring in the heavy snowfall areas of Hokkaido. To increase the stabili...
Factors Affecting the Bleeding Rate from the Basal Part Cut End of Stem in Soybean (Glycine max (L.) Merr.) Seedlings
Bleeding rate Glycine max (L.) Merr Respiration rate Root physiological activity
2009/7/9
The bleeding rate from the stem cut end is considered to reflect the root physiological activity since the bleeding is caused by the active water absorption by root. We analyzed factors affecting the ...

Dominance Decrease in kernel weight F1 Haruyutaka Reciprocal cross Source ability
2009/7/8
The factors that decrease the kernel weight of Hokkaido wheat cultivar “Haruyutaka” in Western Japan were analyzed based on the kernel weight of F1 of the cross with Kyushu cultivar “Daichinominori.” ...
Factors Causing Submergence Damage on Soybean Seedling Emergence under No-Till Culture Conditions
No-till culture Seedling emergence Soybean Submergence damage
2009/7/8
Soybean yield in Aichi prefecture, Japan, has been low and unstable due to excess soil moisture during seeding time. We have been developing the production technology including no-till culture to red...
