Compared with submerged irrigation, the growth of root, accumulation of above-ground dry matter, grain yield and water use efficiency were decreased significantly under dry cultivation.
与水种相比，旱种水稻籽粒中iaa和ZR含量减少，灌浆前、中期ABA含量明显增加，这种差异主要表现在弱势粒上。
The grains of dry-cultivated rice contained less IAA and ZR but more ABA than those of moist-cultivated rice at early and mid grain filling stages, and the differences were mainly in inferior grains.
