【摘要】 本试验从贵阳引进8个食用菊花品种进行引种栽培,研究了吲哚丁酸对食用菊扦插繁殖的影响,植株调整对食用菊生长发育和产量的影响,并对各品种食用菊的物候期、植物学性状、产量及内在品质进行分析比较,结果表明: 1、使用IBA(50mg·L（-1）,100mg·L^-1,150mg·L^-1,200mg·L^-1)进行食用菊花的扦插蘸根处理,插穗的成活率达100%,比对照提高8.75%;生根数平均达到了63根,比对照平均多43根。 2、对于“金龙献爪”、“金勾万卷”、“太真含笑”、“龙丝菊”等四个品种的插穗,促进生根的IBA最优浓度为150mg·L^-1;对于“白雪球”、“倒挂金钩”、“宝紫球”等三个品种插穗,促进生根的IBA最优浓度为100mg·L^-1。 3、通过摘心、整枝、抹芽、疏蕾等植株调整,花序直径比对照增大了138%,单花重量比对照提高了141.4%。 4、各品种育苗37天均可定植于露地;从定植到进入现蕾期需要92～98天,进入现蕾期的平均气温在19.5℃～20.2℃;从现蕾到始花期需要35～42天,进入始花期的平均气温为11.9℃～13.2℃;从始花期到盛花期需要23～30天,进入盛花期的平均气温在4.6℃～10.2℃。 5、“太真含笑”、“白雪球”、“宝紫球”三个品种长势良好,产量高、内在品质好,可以作为山西省今后生产开发的主栽品种。更多还原

【Abstract】 Eight varieties of edible chrysanthemum having been introduced from the city of Guiyang into this experiment to widely cultivate and naturalize, we study the effect of IBA on the stem planting of edible chrysanthemum, the influence of regulation on their development and production, comparison of phonological phase, quantitative characters in botany and their inner quality. The results are as follows:1 Cuttage and root-dipping to the edible chrysanthemum with IBA(50mg · L^-1, 100 mg · L^-1,150 mg · L^-1, 200 mg · L^-1), survival rate of the shoot for cutting reaches 100%, 8.75% increase than the contrast; average number of their rooting is up to 63, 43 increase than the contrast.2 To shoot for cutting of such four types of edible chrysanthemum as "jinlongxianzhua" "Jingouwanjuan" "taizhenhanxiao" "longsiju", the most suitable concentration of IBA to promote rooting is 150mg· L^-1, while to the other types of edible chrysanthemum as "baixueqiu" "daoguajingou" "baoziqiu", the most suitable concentrations is 100mg· L^-1.3 Through regulations as removal, training, shoot erasing and distance, 138% increase of anthotaxy diameter than the contrast.4 Growing seedlings of all types needs 37 day, then the edible chrysanthemum can be transplanted to open ground; from transplantation to budding, 92-98 days, and the average temperature to budding is 19.5 ℃-20.2℃; from budding to flowering, 35-42 days, and the average temperature to flowering is 11.9℃ -13.2℃; from flowering to blossom is 23-30 days, and the average temperature to blossom 4.6℃-10.2℃.5 Among them the three types of edible chrysanthemum as "taizhenhanxiao", " baixueqiu" , "baoziqiu" grow in good condition, in high yield with good inner quality which can be developed in Shanxi province with great effort.更多还原
