Since rice is highly susceptible crops to water stress, it is important to improve drought resistance to increase and stabilize the rice yield under upland cultivation conditions. This study was condu...
Effects of Source and/or Sink Restriction on the Number of Flowers, Yield and Dry-Matter Production in Field-Grown Soybean(Agronomy)
Branches Defloration Defoliation Dry-matter production Main stem Number of floral buds
2009/7/15
Source and sink organs are closely related with each other in the process of soybean yield determination. We examined the effects of source and/or sink restriction on the flowering habit, pod set and ...
Effect of Saline Irrigation During Grain-Filling Period on Dry-Matter Increase of Hulled Rice
Dry-matter increase of hulled rice Grain filling Inferior spikelet Rice(Oryza sativa L)
2009/7/14
The effect of salinity stress on grain filling was studied in two rice varieties(Kala-Rata 1-24 and IR28) with different resistances of yield to salinity. Plants were subjected to saline irrigation(15...
