【摘要】 对新疆野苹果巩留和新源两个种下居群的88个实生株系果实的矿质元素、糖酸组分及其遗传多样性进行研究,并与富士、金帅和红星品种进行比较。结果表明,新疆野苹果的6种矿质元素(Ca、Mg、Fe、Cu、Mn、Zn)、3种糖(果糖、葡萄糖、蔗糖)组分及苹果酸含量的变异系数均在23%以上,表现出丰富的遗传多样性。其中钙平均含量是栽培苹果品种的3·1倍,而且可溶性糖的组成与栽培苹果品种表现出明显的差异。更多还原

【Abstract】 Content of mineral elements,sugar and acid components of fruits in 2 intraspecific populations(Gongliu and Xinyuan County in Ily State) of Malus sieversii(Ldb.)Roem.from 88 seedlings were studied,as well as their contents comparison to three M.domestica Borkh.cultivars(Fuji,Golden Delicious,Starimson).The results indicated that variation coefficients of mineral elements(Ca,Mg,Fe,Cu,Mn,Zn),sugar components(fructose,glucose,sucrose) and malate in M.sieversii seedlings were more than 23%,which revealed rich genetic diversity.The content of Ca in M.sieversii was 3.1 times of that in M.domestica and the sugar composition in M.sieversii was significantly different to that in M.domestica.更多还原
