摘要
研究不同截顶类型对思茅松萌条数量和母株存活的影响,结果表明:采穗母株萌条数量受截顶高度的影响明显,截顶高度8 cm比4 cm的萌条数量多;截顶高度对采穗母株的存活也有较大影响,截顶高度8 cm比4 cm的存活率高.对1年生采穗母株,截顶前的母株高度对采穗母株萌条数量和母株保存率有一定的影响.
The effect of varied stumping measures on the shooting number and the survival rate of mother plant of Pinus kesiya var. langbianensis were researched. It was showed by the results that the number of sprouting shoots was remarkably affected by the remained height after topping, more sprouts could be produced by stumping at 8 cm than stumping at 4 cm above the ground. Moreover, it was showed that the survival rate of the mother plants of Pinus kesiya vat. langbianensis was also influenced by stumping height, the mother plant survival rate after topping at 8 cm was higher than that of after topping at 4 cm above the ground. To one - year - old scion producing mother plants, the sprouting number and survival rate were influenced by the remained height after stumping.
