摘要: 2007-2008年在大田条件下, 以两种不同穗型小麦品种为试验材料, 研究了播期、密度组合对小麦叶面积系数及生育后期净光合速率、叶绿素荧光动力学参数和产量的影响。结果表明:不同播期和密度处理对不同穗型小麦品种LAI、旗叶Pn、叶绿素荧光动力学参数及产量均存在明显影响, 不同穗型小麦品种均表现为晚播高密处理的LAI最小, SPAD值则是早播处理的低。多穗型品种良星99在中播常规播量时其Pn、Fv/Fo和Fv/Fm较大, 产量最高, 大穗型品种洲元9369也是在中播常规播量时荧光动力学参数的各项指标占优。10月12-19日为适宜播种期范围。

Abstract: The field experiment was conducted to LAI, SPAD value photosynthetic (Pn) rate, evaluate fluorscence induction kinetic parameters and grain yield in different sowing date and planting density of two different spike type cultivars during grain filling stage, during 2007 -2008. The results indicated that two different spike type cultvars have shown for LAI smallest was the third sowing date, SPAD value was the first sowing date low. Pn, PS Ⅱ potential activity(Fv/Fo), the maximal quantum efficiency of PS Ⅱ photochemistry(Fv/Fm) and yield were higher in treatment of B_2C_1 for small spike type cultivar (Liangxing99), the same of large spike type cultivar (Zhouyuan9369). October 12 to 19 is the suitable sowing period.

Key words: Wheat, Sowing date, Fluorescence induction kinetic parameters, Yield
