We analyzed the quantitative trait loci (QTLs) for cold tolerance at the booting stage of a cold-tolerant rice variety, Norin-PL8, which harbors cold tolerance genes derived from a cold-tolerant varie...
Studies were conducted to clarify the relation between the rooting ability from flag leaf node and the cool tolerance at the booting stage in rice. Panicles with the flag leaf nodes were taken from pl...
For the purpose of improving the deep irrigation method as a countermeasure of floral impotency due to cool weather by means of a reduction of the necessary water depth to protect young panicles, stu...
The relationships between the tolerance to cool temperature in the booting stage and the grain quality of paddy rice in Hokkaido.
In rice plants a drought at the booting stage is the event most damaging to grain yield because it drastically increases sterility. Our objective was to establish what phosiological processes caused s...
Many water droplets adhere to the surface of a rice panicle located inside the protective sheath of flag-leaf at the booting stage. Since the adhering water is formed by the exudation of liquid water ...
To increase the crude protein content of wheat in the Kyushu district, the amounts of basal fertilizer and top dressing were decreased to 72% of standard and the remaining 28% fertilizer was applied a...
Cool-weather tolerance at the flowering stage of 52 Hokkaido rice varieties was examined in 1998 and 1999. Eight plants having only the main culm were cultivated in small square pots, 15×5×10cm, and ...
Genetic analysis showed that cold tolerance at booting stage of near-isogenic lines (NILs) of Kunmingxiaobaigu was controlled by a gene with large phenotypic variance. One hundred and sixty-four simpl...
By using the parents, Kunmingxiaobaigu, a landrace variety with cold tolerance from Yunnan, China, and Towada, a cold-sensitive variety bred in Japan, as well as their F8 and F9 RIL progenies as test ...
