黄花烟草 Nicotiana rustica 的两个品种 V_2和 V_(12)以及它们的衍生世代 F_1、F_2、B_(c2)和 B_(c12)计6个世代16个家系种植在16个不同的环境中。方差分析表明:母性效应不是变异的主要原因,世代间和环境间的差异以及它们的互作都是极显著的。株高这一性状,在早期只是加性基因起作用,但随着时间的推移,方向显性也逐渐变为重要因素,在一些环境中基因存在上位性效应。我们对 N、P、K 和 Ca 每种肥料的单独效应和不同组合的联合效应作正交比较,结果指出,磷对株高有最大的增加效应,单独施用氮对株高没有影响,至少是在移栽后的早期如此。根据总的平均数模型和相应的肥料效应模型,可以重新构造某一性状在某一特定环境条件下的线性模型。
Two families of Nicotiana rustica V_2 and V_ (12) and their derived generations F_1, F_2, B_ (c2) and B_ (c12) were planted in 16 different families in six generations of six generations. Analysis of variance showed that maternal effect was not the main cause of variation, and the differences between generations and environments and their interactions were all significant. The trait of plant height, which acts as an additive gene in the early stages, has also become an important factor in the direction of dominance over time, and the epistatic effect of genes in some settings. We compared the individual effects of N, P, K and Ca with the individual effects and the combined effects of different combinations. The results showed that phosphorus had the greatest effect on plant height. Nitrogen application alone had no effect on plant height, at least So early after transplanting. Based on the total averaging model and the corresponding fertilizer effect model, a linear model of a trait under a particular environmental condition can be reconstructed.
