Relationship between grain yield and ^(32)p,^(14)C in tiller and panicle of 56 hybrid rices

摘要

In recent years, much progress has been made in China on the relationship between grain yield of F1 hybrid rices and some physiological characters. Experiments were conducted in our plant physiological lab during 1982-1991 to analyze the relationship of the grain yield of F hybrid rice with the distribution and concentration of P and C using isotopes ^32P and ^14C.
