摘要: 在种苗智能化系统调控下探讨莲雾插穗、基质、促根剂等3种因素对扦插生根的影响, 结果表明:木质化及半木质化枝梢带叶插穗其成活率高、根系性状好于落叶枝梢插穗;泥炭土基质的插穗根条数显著地高于沙基质, 根生长量亦明显地高于沙及珍珠岩基质;IBA、NAA、IAA等3种促根剂中以IBA种类效果较好, 其中IBA500×10-6处理对插穗成活率提高及根条数增加有明显作用。Abstract: Effects of cutting, matrix and root promoting agent on rooting of Syzygium Samarangense cuttings were studied under the rapid propagation system of germchit intelligent monitor and control.The results showed that the survival rate of the lignified or half-lignified cuttings with leaves was higher and its root traits were better than that of cutting without leaves.And the amount of roots developed on the cuttings was significantly higher when the cuttings were cultivated in peaty soil than in sand.In addition, longer roots were consistently found on cuttings in peaty soil rather than that in sand or in perlite substrate.Among the treatments of root promoting agent IBA, NAA and IAA, the addition of IBA rendered the best result on rooting.Furthermore, the treatment of IBA 500×10-6significantly increased the survival rate of roots as well as the overall growth of the cuutings.
