Abstract
【Objective】The optimal method of root treatment and embedding in the root cutting seedling of kiwifruit were explored to provide references for making the root material after the transplant of seedlings suitable for breeding rootstock seedlings. 【Method】Using the root of Actinidia chinensis ‘Guihaia 4' seedlings as material, four covering treatments were performed.(horizontal covering, vertical covering, vertical level, vertical exposing the topsoil). There were 12 treatments of root diameter and length(diameter: 2, 5, 8 mm; length: 3, 6, 9, 12 cm), which were represented by 1A,1B,1C,1D,2A,2B,2C,2D,3A,3B,3C and 3D. The emergence rate and basal diameter of seedlings were measured with field sown seedlings as the control. 【Result】The emergence rate of vertical level, vertical exposing the topsoil and vertical covering(97.93%, 90.00%, 78.00%) was significantly different from that of horizontal covering(53.33%) and seed emergence rate(30.00%). Basal diameter of annual root cutting seedlings was significantly greater than that of natural propagation seedlings.No obvious difference was observed among other treatments. Root length and diameter played an evident interactive role in emergence rate. Except treatment 1A and 1B, the seedling emergence rate of the rest treatments was more than 85%. When the root diameter was small(2 mm), the longer root cutting had higher emergence rate. Root length and diameter significantly affected basal diameter of root cutting seedlings. In addition to treatment 1A, 1B and 2B, the basal diameter of the rest treatments was more than 0.6 cm. When the root length was the same, bigger diameter root cuttings produced bigger basal diameter. When the root diameter was 8 mm, the average basal diameter of root cutting seedlings could reach 0.77-0.95cm. 【Conclusion】In kiwifruit rootstock seedling breeding, root cutting was an excellent breeding method. Its emergence rate, in particular the rate of vertical exposing the topsoil, was better than that of natural propagation seedlings.
