毛茉莉扦插繁殖试验

Study on Cuttage Propagation of Jasminum multiflorum

  • 摘要: 以毛茉莉枝条为试材,研究基质、插穗部位对其扦插繁殖的影响。结果表明:毛茉莉扦插7d后可生根,嫩尖在草炭土+蛭石+河沙(1∶1∶1)的基质上扦插生根成活率达100%;基质影响毛茉莉插穗生根长度和粗度,在草炭土+珍珠岩(1∶1)基质上插穗的根最长,扦插在河沙基质上的不定根最粗;插穗部位影响毛茉莉插穗的第1根形成时间、2/3以上插穗生根时间、生根长度、粗度和生根率,且其影响有共同的趋势,即嫩尖>嫩枝>老枝;基质和插穗部位对生根数、愈伤组织形成时间的影响均不显著;基质对第1根形成时间、2/3以上插穗生根时间和生根率影响均不显著。

     

    Abstract: The effect of substrate properties and the position of the cuttings taken from the shoots of Jasminum multiflorum on the cuttage propagation were studied. The results showed that rooting of the J.multiflorum green cuttings took place in 7 days, and the rooting rate of the tender tip cuttings reached 100% in the substrate composed of peat soil+ river sand+ vermiculite(1∶1∶1).It was showed that different substrates significantly affected on the young root length and diameter.The cuttings grown in the substrate consisting of peat soil+ perlite(1∶1) had the longest roots, while the cuttings grown in the pure river sand substrate produced roots with the maximum basal diameter.The position on the shoots where the cuttings were taken from could affect on the time when the first root took place and the rooting time duration by which 2/3 of the cuttings had rooted, on the length and diameter of the new roots,and on the rooting ratio as well. There was a common tendency in terms of effect intensity by the position on the shoots as tender tip > softwood > basal part of the shoots.The effect of substrate properties and the position on the shoots where the cuttings were taken from on the root number and callus emergence time was not significant, the effect of substrate on the first root emergence time,the rooting time duration by which 2/3 of the cuttings had rooted, and on the, rooting ratio was not significant,either.
