杂交相思母本苗高对扦插效果的影响

摘要

Experiments were conducted to study the effects of different grade maternal plants of Acacia mangium × A. Acuriculaeformis on coppice shoot quality, cutting survival rate and biomass of cutting stocks. The results showed that the performance of cuttings was positively related with the height of maternal plant. The maternal plants with superior quality produced more shoots and high quality cutting stocks with higher survival rate.%以不同高度等级的杂交相思实生苗作扦插母本,通过对萌条数量、扦插成活率、苗高、地径、根系生长及生物量的影响试验观测,结果表明:不同高度等级实生苗木作母本与萌条数量、扦插成活率、苗高、地径、根系生长及生物量差异显著；定植的母株越高,扦插苗成活率越高,扦插苗质量越好.
