麦冬苗用IBA、NAA和IBA+NAA分别以10、20、30和40ppm浸泡16小时,在水培条件下经7、15和50天三次测定,结果表明,处理7天时过氧化物酶活性普遍上升,15天时下降,50天时又上升,但无论上升或下降,IBA+NAA引起的变化都比IBA和NAA显著;处理7天的蛋白质含量上升,而15天和50天的IBA+NAA(10—20ppm)均比其它生长素类型和对照高,浓度为20ppm的,其蛋白质含量均较高;处理50天后测定根数、根长和根粗,IBA+NAA混合液均优于其它二种单一生长素。
Ophiopogon japonicus was immersed in 10, 20, 30 and 40 ppm of IBA, NAA and IBA + NAA respectively for 16 hours and 7, 15 and 50 days under hydroponic conditions. The results showed that peroxidase activity Generally increased, decreased at day 15 and then increased at day 50, but changes in IBA + NAA were significantly greater than those in both IBA and NAA, regardless of ascent or descent; protein content increased seven days after treatment, while IBA + NAA at 15 and 50 days 10-20ppm) were higher than those of other auxin types and controls. The content of protein was higher when the concentration was 20ppm. After 50 days treatment, the number of roots, root length and root diameter, IBA + NAA mixture were better than the other two A single auxin.
