| 摘 要： | 为加快山核桃Carya cathayensis 营养繁殖和保持优良性状, 以3 年生山核桃实生苗主根为材料, 用不同种类和不同质量分数的生长调节物质处理后进行扦插繁殖试验。结果表明, 山核桃根插属于愈合组织生根型;50 ～ 100 mgkg-1萘乙酸(NAA )处理18 h 能有效提高生根率、新根数、新根长和新根根径;但300 mgkg-1NAA 抑制生根, 6-苄基腺嘌呤(BA )处理对根插无效甚至不利。探讨了解决山核桃根插条来源的途径及进一步提高生根率的思路。表6 参9

| Abstract: | An experiment on the taproot cutting of three-year-old seedlings of Carya cathayensis which were treated with different types of hormones of different mass fractions was carried out to accelerate their vegetative propagation and keep their excellent properties .The results indicated that the adventitious roots were developed from the callus , and the rooting rate , the number of new roots , the length of new roots and the diameter of new roots could be improved effectively with the treatment of 50 -100 mgkg-1NAA for 18 hours.However , 300 mgkg-1 auxin NAA could inhibit the formation of new roots .The cytokinin BA brought bad or no effects on the rooting of Carya cathayensis .The sources of root cutting and the measures for improving rooting rate were also studied .
