研究分枝基部刮削(刮茎处理)和ABT1号生根粉对蛇皮果高空压条生根的影响,为提高蛇皮果高空压条育苗成活率提供依据.对蛇皮果分枝基部进行刮削和涂抹ABT1号生根粉溶液处理,以不刮削和涂抹自来水为对照,间隔一段时间测定其叶长和根数,并据此评估压条生长表现和生根率.研究结果表明:刮茎处理的压条生根率和生根数显著高于未刮茎处理的压条,叶的生长量极显著低于对照,但生长量为正值.涂抹ABT1号生根粉溶液的压条其生根数显著大于不涂生根粉的压条,而且生根数与ABT1号生根粉浓度成正相关,但以1000 mg/L性价比最高.%The effects of scraping stem and applying ABT #1 rooting powder at stem surface on the rooting of Salacca zalacca upper air layering were studied to raise the survival rate of seedlings. By taking no scraping stem and wiping water on the stem as the controls, the S. zalacca seedlings were treated. The leaf length and number of roots of the layerage seedlings were measured at regular intervals, thereby evaluating the seedlings' growth performance and rooting rate. It was concluded that the stem-scrapped seedlings had a significantly higher rooting rate than that of no stem-scraped seedlings but had a very significant low leaves growth than non-scrapped seedlings. Besides the rooting numbers of the seedlings treated with ABT #1 rooting powder were significantly greater than that of no-wiping ABT #1 rooting powder, the rooting number was positively correlated to the concentration of applying ABT#1 rooting powder, when the concentration was 1000 mg/L, the rooting efficiency (performance price ratio)reached the peak value.
