摘要
本文以祁连圆柏半木质化嫩枝为试验材料,选用S-3307、ABT1号和IBA三种生长调节剂及不同浓度(100 mg/kg、200 mg/kg和300 mg/kg)研究不同处理对祁连圆柏扦插苗的影响.结果表明:处理A1的成活率最高,为46.10％,其苗高、地径、新梢、侧根数、侧根长分别为24.41 cm、2.27 cm、7.39 cm、9.10根、6.73 cm;其次是处理B3,成活率为43.60％,其苗高、地径、新梢、侧根数、侧根长别为26.41 cm、2.19 cm、7.75 cm、9.30根、4.94 cm.生产上,建议S-3307 100 mg/kg和ABT1 300 mg/kg在祁连圆柏扦插生根时使用.
Abstract
The semi-lignified shoots of Juniperus przewalskii Kom.were used as experimental materials,and three growth regulators,S-3307,ABT1 and IBA,and different concentrations(100 mg/kg,200 mg/kg and 300 mg/kg)were used to study the effects of different treatments on the cuttings of Juniperus przewalskii Kom.The results showed that the survival rate of treatment A1 was the highest at 46.10％,and the seedling height,ground diameter,new shoots,number of lateral roots,and lateral root length were 24.41 cm,2.27 cm,7.39 cm,9.10 roots,and 6.73 cm,respectively.The survival rate of B3 was 43.60％,and the seed-ling height,ground diameter,new shoots,number of lateral roots,and lateral root length were 26.41 cm,2.19 cm,7.75 cm,9.30 roots,and 4.94 cm,respectively.In terms of production,it is recommended that S-3307 100 mg/kg and ABT1 300 mg/kg should be used in the rooting of cuttings of Juniperus przewalskii Kom.
