摘　　要：以红花新几内亚凤仙幼苗为试材,采用砂培法,以不加铜的日本园试配方营养液为对照,研究3.2×10-9、3.2×10-7、3.2×10-6、3.2×10-5 mol/L不同浓度的铜对其叶片、开花性质及花瓣表皮细胞色素分布等观赏性的影响。结果表明:当营养液中铜浓度为3.2×10-7 mol/L时,红花新几内亚凤仙的花色最深、花瓣上表皮细胞内形成的色素数量最多;铜浓度为3.2×10-6mol/L时,红花新几内亚凤仙的开花数和花朵直径最大。Taking the seedlings of red Impatiens hawkeri as test material,with Japanese garden test nutrient liquid as control,the effects of different concentrations 3.2×10-9,3.2×10-7,3.2×10-6,3.2×10-5 mol/L copper on the landscape of red Impatiens hawkeri were studied through solution sand culture.The results showed that when copper concerntrition was 3.2×10-7 mol/L in nutrient solution,red Impatiens hawkeri had the deepest flower color and largest number of pigment;when copper concerntrition was 3.2×10-6 mol/L,red Impatiens hawkeri had the biggest flower diameter and the most flowers among all copper treatments.
