叶用型食用菊品种筛选

Selection of Edible Leaf-use Chrysanthemum

为丰富叶用型食用菊类型,从现有11个品种中初步筛选出叶片口感好、生长势旺盛、叶表皮绒毛少的材料,进行营养成分及产量测定,并以叶片营养成分含量各指标及产量作为叶用型菊花筛选评价要素,建立模糊综合评价法模型,通过对3组依据不同的侧重点构建的权重模型的结果进行计算分析,筛选符合要求的叶用型食用菊材料。结果表明,四倍体菊花脑、二倍体菊花脑、开菊1号综合评价营养成分较好,产量预测值分别为711.52、346.66、424.38 kg·667 m-2;水分含量分别为80.43%、80.77%、82.01%;有机酸含量分别为0.42%、0.34%、0.31%;可溶性糖含量分别为21.09、15.47、4.42 mg·g-1;可溶性蛋白含量分别为17.93、20.02、12.48 mg·g-1;纤维素含量分别为45.99、24.38、95.37 mg·g-1;维生素C含量分别为1.19、1.63、0.91 mg·g-1。模糊综合评价法分析结果表明,四倍体菊花脑、二倍体菊花脑、开菊1号3个品种总体得分相对较高,3组权重总体得分均大于0.4,得分均优于其他材料,可作为优良叶用型食用菊材料。本研究为利用模糊综合评价法筛选符合市场要求的叶用型食用菊品种奠定了一定的理论基础。

In order to enrich the type of edible leaf-use chrysanthemums,the new materials that with strong growth potential and low leaf epidermis villi were screened out from the existing 11 materials.The parameters of yield and the nutrient contents were used as the evaluative features to establish a fuzzy synthesize evaluation method.Three models were built by different main points to calculate the results.The results showed that the nutritive composition of the chrysanthemum nankingense(4X),chrysanthemum nankingense(2X)and Kai Ju1 was better,and the predicted yield were 711.52 indicator,346.66 and 424.38 kg·667 m-2,respectively;water content were 80.43%,80.77%and 82.01%,respectively;organic acid content were 0.42%,0.34%and 0.31%,respectively;soluble sugar contents were 21.09,15.47 and 4.42 mg·g-1,respectively;soluble protein content were 17.93,20.02 and 12.48 mg·g-1,respectively;fibre content were 45.99,24.38 and 95.37 mg·g-1,respectively;vitamin C content were 1.19,1.63 and 0.91 mg·g-1,respectively.It showed that the chrysanthemum nankingense(4X),chrysanthemum nankingense(2X)and Kai Ju1 had more significant advantages with the evaluation method.The weighted overall scores of three groups were greater than 0.4.The findings of the current study suggested that these materials were good for edible leaf-use chrysanthemums.The fuzzy synthesize evaluation method provided a great theoretical way to select edible chrysanthemum materials.
