摘　　要：通过3个彩麦品种与3个不同品质类型的普通小麦品种的产量形成特点及其生理基础的比较研究。结果表明:彩色小麦产量低的原因在于子粒产量形成关键期,其光合生产能力及物质转运能力差;而根系吸收能力及子粒库容活性不是限制因素,且彩色小麦在生育后期具有较强的抗逆性,表现在"源—库—流"系统均有较强的活性。The differences and physiological basis of yield formation between 3 color wheat varieties and 3 general wheat varieties with different quality were studied. The results showed that the reasons of low-yleld in three color va- rieties were that their photosynthetic productivity and material transports capacity were lower than those of 3 general varieties at the critical periods of grain yield formation. There were no big difference on root-system absorbency and grain storage capacity activity between two types of wheat varieties. Stress resistance of color varieties was stronger at the late growth period than that of general ones, indicating the higher activities of source-sink-flow systems in color varieties.
