南方紅豆杉1年生萌蘗條插穗生根率最高,而1年生側(cè)枝插穗來源易,數(shù)量多。以NAA50μg/mL＋I(xiàn)BA50μg/mL,處理1年生側(cè)枝插穗8h,在善土-蛭石(1:1)的苗床上,插穗成苗率達(dá)60%以上。

The highest rooting rate was obtained from the annotinous tillering shoots of Ta.zus chinensis var. mairei. but this kind of shoot was too scanty to be used as a source of cutting for rapid propagation. On the contrary,numerous annotinous lateral shoots were easy to obtain. The effects of different cutting beds and plant growth regulators on the rooting of annotinous lateral shoots were studied.It was found that more than 60% of rooting cuttings could be obtained on the loam,verculite=1:1 cutting bed supplemented with 50 mg/L NAA+50 mg/L IBA treated for 8 hours.
