运用１４ Ｃ标记示踪技术，测定诱变处理后幼苗的光合作用、呼吸作用，并考查碳素营养运转情况，结果表明：不同处理对光合作用影响很小，但呼吸作用随复合剂量加大而增加，同时输出物质减少。
The photosynthesis and respiration of the seedlings after mutagenic treatment were determined by 14 C-labeled tracer technique. The results showed that the effects of different treatments on photosynthesis were insignificant, but the respiration increased with the increase of the compound dosage Increase, while reducing the output material.
