| 摘 要： | 对亚种间杂交稻组合ＰＥ０３７×０２４２８光合产物积累和分配的研究结果表明：ａ．亚种间杂交稻较品种间杂交稻具有更大的光合产物积累优势，但实际产量不高；ｂ．亚种间杂交稻光合产物积累在乳熟末期前各时期的比重较大，后期则比重较小；ｃ．亚种间杂交稻各不同生育时期光合产物产量与经济产量的关系较为复杂，提高移栽至孕穗期的生物产量对增加经济产量作用不大．

| Abstract: | Accumulation and distribution of photosynthetic
dry matter of intersubspeeicshybrid rices(IHR)were studied and the resules summaried
follows:a.The IHR showedhetorosis in accumulation of photosynthetic dry matter compared
With the varieties, but notin grain yield.b.The accumulation rate of photosynthetic dry matter
brfore late milkingstageis much more than at late milking stage.c. The relationship between the
yield of phyotosyn-thetic dry matter and the economic yield of IHR is more complicated. The
increase ofbiomass from the transplanting to botoing stage does not contribute muchto the
economicyield. |
