| 摘 要： | 对亚种间杂交稻ＰＥ０３７×０２４２８籽粒结实性状和籽粒相对含水率的研究表明：亚种间杂交稻４月上、中旬和６月上、中旬播种有利其籽粒的充实，５月初播种则结实率最低：亚种间杂交稻的结实率受源、库影响明显；结实率低的主要原因，是由于其籽粒相对含水率的变化幅度小

| Abstract: | Grain setting rate and relative moisture content of interspeies hybrid rices(IHR)are studied which showes the resultes as follows:Sowing IHR in the first twenty days of Aprit or the first twenty days of June is helpful for grain setting but sowing time at thebeginning of May results in the lowest grain setting;The grain setting rate of IHR is affected deeply by source-tank type,but the low grain setting grate of IHR is not determined by source-tank;The low grain setting grate of IHR is due to little change of relative moisture Coutent. |
