无性繁殖的重要方式之一是扦插,即通过在母体植株上切离下来根、茎、叶等营养体,利用细胞的全能性,在一定的条件下将营养体发育成一棵完整的植株。嫩枝扦插是扦插的其中一种形式,即利用植物生长期间的半木质化枝条作为繁殖材料,主要优点表现在苗木发根快、成活率高、材料简便易得、成本低。采用嫩枝扦插方式进行无性繁殖,繁殖系数高,1年可行多次扦插,且扦插苗性状特征明显,纯度较高。本文研究了不同生根剂配方研究对“蒙杞l号”枸杞新品种苗木嫩枝扦插成活率的影响。
One of the important ways of asexual reproduction is cutting. That is, by cutting off the vegetative bodies such as roots, stems and leaves on the parent plant, the vegetative body can be developed into a complete plant under certain conditions by utilizing the pluripotency of cells. Softwood cutting is one of the forms of cutting. That is, the use of semi-lignified branches during plant growth as the propagation material, the main advantages of the seedling hair root fast, high survival rate, the material is simple and easy, low cost. Softwood cutting method is adopted for asexual reproduction, propagation coefficient is high, multiple cutting is feasible for one year, and the characters of cuttings are obvious and the purity is high. In this paper, we studied the effects of different formulations of rooting agents on the survival rate of shoots of “Wolfberry No.1” and “Mengqi No.1”.
