摘要
对小麦品种小区试验的边际效应研究结果表明:不同品种小区边行的有效穗、穗粒数、千粒重、穗重及产量均有较明显的优势;产量的边行优势平均达30.24%,有效穗的优势平均达8.29%,穗粒数平均达17.46%,千粒重平均为2.65%,穗重平均达20.33%;不同品种间边行优势具有明显的差异,这种差异导致试验准确度受到一定影响;边际效应在小区试验中应予以消除。
The edge effects of plots in wheat cultivar tests are described in this paper.Experimental results showed:No. of panicles,No.of grains,grains wt.and yield of side line plants inthe plots have clear suporiority.Mean marginal superiority is 8.29%to No. of panicles,17.46%toNo. of grains,2.65%to 1000 grains wt.,20.33%to the yield.Marginal superiority is different fromvarious varieties.This difference results in influence on the experimental accuracy.
