摘要
为了明确干旱胁迫条件下SODM对水稻产量和品质的影响,测定了不同水分条件不同SODM处理下水稻光合性能、内源激素、产量及产量因素、水稻品质等指标。结果表明:SODM处理能够显著增加水稻剑叶中叶绿素的含量、提高光合速率、改善水稻光合性能。SODM的施用能够增加细胞分裂素的含量而降低脱落酸和乙烯的含量。同时,SODM的施用提高了水稻的产量,改善了水稻的出糙率、精米率等加工品质和外观品质。
For understanding effect of SODM on yield and quality of rice under drought stress condition, photo-synthetic and physiological characteristics, endogenous hormones, yield and yield component, quality of rice treated with SODM under different soil water condition were measured. The results showed that the treatment of SODM could obviously increase chlorophyll contents of rice flag leaves, raise photosynthetic rate and improve photosynthetic characteristics. SODM could increase cytokinin contents, and decrease abscisic acid and ethylene contents. Meanwhile,SODM could increase yield of rice, and improve processing quality, including brown rice rate（BRR） and head rice rate（HRR） and appearance quality.
