摘　　要：为筛选亲和力优良、适宜嫁接的砧木品种,以主栽油茶Camellia oleifera品种‘赣无2’和‘长林4号’为接穗,采用芽苗砧嫁接法嫁接‘赣60’‘赣无2’‘长林4号’‘赣石83-4’‘长林53号’和越南油茶Camellia drupifera 6个品种(种)的实生芽苗,测定不同处理的嫁接成活率、苗高、地径、叶片数、分枝数等指标,利用隶属函数法综合评价嫁接苗的生长情况。结果表明,接穗‘赣无2’和‘长林4号’的砧穗组合中,分别以‘赣60’、越南油茶为砧木的嫁接苗生长最佳,一年生苗成活率分别为94.08%、82.09%,次年苗高和地径生长量分别为16.54 cm、19.24 cm和0.43 mm、1.08 mm,一年生苗叶片数分别为8.57片·株^(−1)、7.14片·株^(−1),二年生苗分枝数分别为1.82枝·株^(−1)、3.1枝·株^(−1);均以‘长林53号’作砧木的嫁接苗生长发育较差,成活率不足72%。以上研究结果可为江西省油茶嫁接苗的科学培育提供理论指导。In order to select stock varieties suitable for growth in Jiangxi Province and with excellent grafting affinity,‘Ganwu 2’and‘Changlin 4’,the main Camellia oleifera cultivars in Jiangxi Province,were used as scions,and six stock varieties were grafted by bud seedling rootstock grafting,and the survival rate,seedling height,ground diameter,leaf number,branch number and other indexes of different treatments were determined,and the growth of grafted seedlings was comprehensively evaluated by the membership function method.The results showed that the rootstock combinations of the scions‘Ganwu 2’and‘Changlin 4’,the growth and development of grafted seedlings with‘Gan 60’and Camellia drupifera Lour as rootstocks were better,with one-year survival rates of 94.08%and 82.09%,respectively.the height and diameter growth of the seedlings in the following year were 16.54 cm,19.24 cm,0.43 mm,and 1.08 mm,respectively.the number of leaves in the one-year seedlings was 8.57 and 7.14 pieces per plant,and the number of branches in the two-year seedlings was 1.82 branches and 3.1 branches per plant,while the growth and development of grafted seedlings of Changlin 53 stock were poor,survival rate of less than 72%.The above research results can provide theoretical guidance for the scientific cultivation of grafted C.oleifera seedlings in Jiangxi Province.
