摘要： 为研究所引进的越南金花茶的嫁接亲和力，以塔姆岛金花茶、箱宁金花茶、箱田金花茶、罗斯曼金花茶4 种越南金花茶为嫁接接穗，以香花油茶、茶花‘黑牡丹’、‘毛紫’茶花、普通油茶为嫁接砧木，对4种越南金花茶嫁接亲和性进行初步研究。结果表明，塔姆岛金花茶分别与香花油茶、茶花‘黑牡丹’、‘毛紫’茶花、普通油茶4 种砧木小苗开展嫁接，其中与香花油茶嫁接成活率、抽梢率以及新稍生长情况最好，分别为96.8%、93.5%、13.8 cm；罗斯曼金花茶与香花油茶砧木的2 种不同砧高以及3 种生长调节剂处理开展的12 种组合嫁接效果最好，成活率达90.0%的组合有6 种，达80.0%的有3 种，其他3 种也达70.0%以上；4 种越南金花茶分别与香花油茶大砧嫁接，其中罗斯曼金花茶和塔姆岛金花茶的成活率、抽梢率、新稍长生长情况最好，箱田金花茶和箱宁金花茶成活效果较差；塔姆岛金花茶与香花油茶开展的不同时间的小苗嫁接和大砧嫁接对比表明，8 月嫁接成活效果最好。4 种越南金花茶中，塔姆岛金花茶和罗斯曼金花茶与4 种砧木嫁接亲和力最高，箱田金花茶和箱宁金花茶与4 种砧木嫁接亲和力较低。4 种砧木品种中，香花油茶与越南金花茶新品种嫁接亲和力最好，其次是‘毛紫’茶花。

Abstract: Grafting compatibility of four Section chrysantha species of Vietnam, C. tamdaoensis, C. phanii, C. hakodae, C. rosmannii, with different rootstocks was investigated. These Section chrysantha species are native to Vietnam. The camellia rootstocks being tested were C. osmantha, C. japonica‘Hei Mu Dan’, C. ‘maozi’, and C. oleifera. It was found that when grafted on young rootstock seedlings, C. tamdaoensis had the highest survival and sprouting rates and the largest new stem growth. When tested with 12 combinations of two different heights of rootstocks and three different types of growth regulators, C. rosmannii and C. osmantha showed the highest compatibility, with an over 70% survival rate. In particular, nine of 12 combinations resulted in at least 80% survival rate and six combinations led to at least 90% survival rate for C. rosmannii when grafted on C. osmantha. C. rosmannii and C. tamdaoensis showed higher survival and sprouting rates and larger new stem growth than C. phanii and C. hakodae, when grafted on big C. osmantha rootstocks. It was also found that the optimal month for C. tamdaoensi grafting with C. osmantha as rootstock was August. Overall, C. tamdaoensis and C. rosmannii performed better than the other two Vietnamese Section chrysantha species on the tested rootstocks. C. osmantha was found the best rootstock for these Vietnamese Section chrysantha species, followed by C. ‘maozi’.
