Effects of Density on Seed Yield and Quality of Double-low Rape Suyou 7
摘要
Abstract
[Objective] To research the effects of density on seed yield and quality of double-low rape Suyou No. 7. [Method] Through field test, we researched the effects of density on the yield, yield component factor, effective pod number, effective branch number and quality character. [ Result] With the increase of density, yield showed a tendency of first increase and the decrease, yields of rape under different planting densities had extremely signficant differences. Low density significantly enhanced the effective pod number per plant. With the de-crease of density, effective pod number per plant reduced, pod number per unit area firstly enhanced and then reduced. However, density had little impacts on seed number per pod and 1000-grain weight. Therefore, high yield was mainly deternimed by effective pod number per unit area. With the increase of density, principal axis and effective pod number of primary branch reduced, effective pod number of secondary branch and effective branching number per plant significantly reduced. Seed oil content and protein cotnent reduced with the increase of densi-ty. [ Conlcusion] Under the test condition, the proper planting density of Suyou 7 was 135000 plants/hm2 in order to obtain relaitvely high yield and to ensure the qualtiyof double low.关键词
