摘要
全光喷雾条件下进行了不同激素处理和不同时间超声处理的绞股蓝(Gynostemma pentaphyllum(Thunb.)Makino)的扦插试验。结果表明,吲哚乙酸(IAA)处理的绞股蓝插穗平均发根数极显著高于吲哚丁酸(IBA)、萘乙酸(NAA)和对照(P<0.01),吲哚乙酸(IAA)处理的绞股蓝插穗的平均最长根长极显著高于对照、吲哚丁酸(IBA)和萘乙酸(NAA)(P<0.01);不同时间的超声处理对插穗的平均发根数和平均最长根长均无显著差异(P>0.05)。插穗的最长根长和发根数存在着线性关系,其回归方程为y=8x-3.409。
Under the full sunlight spray conditions,cuttage experiment of Gynostemma pentaphyllum were conducted with different hormone treatments and different time periods of ultrasonic treatments. Result showed that treatment of IAA produced the average number of roots remarkably more than treatments of IBA,NAA and CK,respectively(P<0.01)and the average length of the longest roots significantly longer than CK,IBA and NAA treatment also.The different time periods of ultrasonic treatment hasn't generated effect on the average number of roots and length of longest roots.The length of the longest roots has linear relation to root numbers,with the regress equation to be y=8—3.409x.
