研究了ABT1号、GGR6号、萘乙酸(NAA)3种外源植物生长调节剂对金叶莸全光照喷雾嫩枝扦插效果的影响。其结果表明:影响生根量、生根长度的主要因素是处理时间。下部插穗采用质量分数为200mg/kg的NAA浸泡0.5h时,生根量、生根长度最好;上部插穗采用质量分数为100mg/kg的ABT1号浸泡0.5h时,生根量、生根长度最好。上部插穗生根量、生根长度显著高于下部插穗。
Effects of exogenous plant growth regulators, ABT1, GGR6 and NAA on softwood cutting efficiency of Allium mulberry leaves were studied. The results showed that the main factors affecting the rooting and rooting length were the processing time. The rooting amount and rooting length of the lower cuttings were best when the NAA of 200mg / kg was soaked for 0.5h. The rooting amount and rooting length of the upper cuttings were the best when the cuttings were soaked with 100mg / kg ABT1 for 0.5h. The rooting amount and rooting length of the upper cuttings were significantly higher than those of the lower cuttings.
