1993
Amano T. | Zhu Q. | Wang Y. | Inoue N. | Tanaka H.
Analysis of the characteristics of grain production of 965 gm(-2) obtained by Shan +You 63 (F1 hybrid rice) in 1991 was carried out. Absorption of nitrogen reached 21 gm(-2) up to the time of heading, and a large capacity of grain yield (50,360 spikelets per centiare) was obtained. Efficiency of increase in spikelet number per centiare by absorbed nitrogen up to heading was essentially the same as in west Japan. Mean Leaf Area Index 10 days before heading became exceptionally large (10.18). A large amount of translocation of accumulated simulation products before heading improved the percentage of ripened grain. Increase in translocation of assimilated products stored in the culm and leaf before heading may remarkably increase yield in China.
