金叶络石以苗繁苗技术研究

The technique of propagating buds on Trachelospermum asiaticum ‘Ougonnishiki’

以金叶络石组培苗为试验材料,开展了不同的扦插基质、扦插时期、植物生长调节剂种类、KIBA速沾浓度及速沾时间对金叶络石组培苗以苗繁苗的影响试验。研究结果表明:金叶络石组培苗扦插基质以泥炭土+珍珠岩(体积比1∶3)为宜,成活率、生根数和根长最高,分别为97.2%、12.1条和4.57 cm;适宜的扦插时期是6月和9月,扦插成活率达95%以上。用植物生长调节剂浸泡或速沾插穗基部,500～700 mg/L KIBA速沾插穗10 s的处理效果较佳,成活率97%以上。

Using Trachelospermum asiaticum ＇Ougonnishiki＇ tissue culture seedlings as test material,the effect of different media,cutting periods,plant growth regulator type,treatment with different concentration and time of KIBA were studied.The results showed that： T.asiaticum ＇Ougonnishiki＇ suitable medium is the matrix of turf ＋ Perlite（volume ratio 1 ∶ 3）.The survial rate,rooting number and root length were 97.2% 、12.1 and 4.57 cm respectively.The appropriate cutting period is June and September,the survial rate is up to 95%.Using plant growth regulator to soak or fast treat cutting base,the better treatment is by 500~700 mg/L of KIBA for 10 s,and the survial rate is up to 97%.
