| 摘 要： | 在土沉香天然分布区之一的云南省普洱市西盟县进行了这一珍贵树种的扦插和嫁接繁殖试验.试验结果表明,土沉香属于扦插难生根树种,愈伤组织生根类型,在试验设计的几个处理中,生根率最高的是ABT 2号100 mg/L处理的半木质化插条,生根率达22%,其次是NAA 100 mg/L处理的半木质化插条和ABT 2号100 mg/L处理的1 a生木质化插条,生根率均为12%,插穗假活时间长达30~40 d,生根所需时间约50~90 d,采用半木质化接穗在夏季进行切接,30 d左右成活,嫁接成活率达52%.

| Abstract: | The experiment was focused on asexual propagation of Aquilaria sinensis in Ximeng county,Yunnan,one natural distribution area of this rare species,including cutting and grafting.The results showed that the rooting ability of Aquilaria sinensis was weak after cutting,and it belongs to the type of callus,The rooting rate about cutting of semi-lignified branches with ABT #2 100 mg/L treatment was the highest at 22%,followed by the cutting of semi-lignified branches with NAA 100 mg/L treatment and cutting of lignified branches with ABT #2 100 mg/L treatment,both were 12%,the false living time was as long as 30 to 40 days,it needed 50 to 90 days to rooting,But in spite of some shortages,the grafting survival rate of semi-lignified branches in summer was 52%,with about 30 days to healing. |
