对于影响针叶树种插条生根潜力的因素作了研究,目的在于改进快速无性繁殖的方法。在遗传限度范围内,根的再生能力在相当程度上取决于生根基质(按:例如砂、土壤等),对质量、扦插的日期、材料植物的年龄和生理状况、插条材料的年龄和它在植物体上的位置以及化学处理。硬枝插条的效果最好,因为它具有较高含量的植物生长素、碳水化合物和形态学上的根原始细胞。用它要比取自正在生长的嫩梢作插条,能提高生长速度2.5～5倍。
Studies have been conducted on the factors that affect the rooting potential of coniferous cuttings with the aim of improving rapid clonal propagation. Within genetic limits, the ability of roots to regenerate depends to a large extent on the rooting substrate (by: eg sand, soil, etc.), the quality, the date of cuttings, the age and physiology of the material plant, the age of the cuttings material and its The location on the plant and the chemical treatment. Hard cuttings are best because they have higher levels of auxins, carbohydrates, and morphologically primitive root cells. Use it from the growing young shoots for cutting, can increase the growth rate of 2.5 to 5 times.
