色素万寿菊品比试验与相关分析

在露地栽培了9个品种的色素万寿菊,调查其株高、茎粗、株幅、花径、产量等指标,并对这些性状进行相关分析,结果表明:Ⅲ号品种的产量最高,各项形态指标优良,适合露地种植;Ⅰ和Ⅵ号产量虽次于Ⅲ号品种,其它形态指标与Ⅲ号品种相差不多;Ⅸ和Ⅷ号品种产量最低,其余品种表现介于Ⅵ和Ⅸ号之间;小区产量与株高、花径、平均花瓣层数呈极显著正相关,与株幅、单株花数呈显著相关.

Comparison and Correlation Analysis of Various Varieties of Pigment Marigold

Nine pigment marigolds' varieties were cultivated in open ground.The plant height,plant amplitude,diameter of flower,yield etc.were investigated,and correlation analysis for these characters.The results indicated that the yield of the third one was the highest,each character was well and suit for planting outdoor.The first one and the fourth one was only lower than the third one,but other characters were similar to it.The yield of the eighth one and the ninth one was the lowest.The performances of other varieties were between the sixth one and the ninth one.Plot yield was special significant positive correlation with the plant height,diameter of flower and average petal layers,while significant positive correlation with plant amplitude and flower quantity per plant.
