摘　　要：本试验以小白菜为材料,研究了缺铁胁迫对小白菜光合特性及品质的影响。结果表明:缺铁胁迫抑制了小白菜的生长,降低净光合速率(Pn)、Fv/Fm、Fv/Fo和ФPSII,增加了1-Fv′/Fm′;缺铁胁迫增加了小白菜叶片硝酸盐的积累,降低了可溶性蛋白和Vc的含量。In this paper, Chinese cabbage （Brassica Chinensis L. ） was used to study the effects of iron deficiency on photosynthetic characteristics and quality. The results showed that iron deficiency significantly inhibited growth, decreased Pn, Fv/Fm , Fv/Fo and ФPSII, and increased the 1- Fv＇/ Fm＇; Iron deficiency increased the accumulation of nitrate and decreased the contents of soluble protein and Vc.
