摘要
１９９４年秋和１９９５年春，在楚雄市紫溪山用华山松和云南松作砧木，对五针白皮松进行了异砧嫁接试验研究。初步结果表明，用华山松作砧木较云南松砧木嫁接成活率高，且长势旺，平均成活率相差１０．５％；长势相差也较大，春季嫁接较秋季成活率高，平均成活率相差２２．６％．从近两年的嫁接株生长情况看，已获得初步成效，这对保存和扩大这一珍稀濒危树种具有重要意义．
The heterogeneous-stock grafting test of Pinus sguamata in two stocks of P. armandi Franch and P. yunnanensis Franch was conducted in Zixi mountain,Chuxiong City in autumn of 1994 and spring of 1995. The results showed that:(1)P. armandi was better than P. yunnanensis,and the difference of grafting survival rates between two stocks was 10.5%;(2) grafting in spring was better than that in autumn,and the difference of grafting survival rates between two seasons was 22.6%. This study clould be conducive to conservation and plantation of the rare Pinus sguamata.
