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。
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.
