分布方式对不同穗型水稻群体穗的影响

Effect of Panicle Distribution Mode on Different Panicle Type Rice Population

有序群体可以使弯穗型群体穗角增大、穗长增加,有利于大穗形成。直立穗型品种比弯曲穗型品种更适合于无序栽培方式。分布方式对产量及生物产量的影响均达到显著水平,有序群体的产量显著高于无序群体。

Ordered population could augment panicle angle and panicle length,which fa-vored the formation of large panicle,erect panicle variety was more fit out-of-order cultivation than bending panicle variety.Distributing mode had significant influence on yield and biologi-cal yield,yield is higher in ordered population than that in out-of-order population.
