Study on Cuttage Propagation of Jasminum multiflorum

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.
