1989年原汕头市柑桔研究所从福建长泰县引入“岩溪晚芦”接穗,以酸桔作砧木嫁接,试种于饶平、潮安等地,迄今栽植面积达6.8hm~2,共10200株,已先后进入结果期。据观察,该株系果实迟熟性状表现稳定,比普通椪柑成熟期晚两个月以上,并能保持普通椪柑固有的优良性状。 In 1989, the former Citrus Research Institute of Shantou introduced “Rock Creek Late Lo” scion from Changtai County, Fujian Province, grafted with sour orange as rootstock, and planted it in Raoping and Chaoan so far. The planting area so far reached 6.8hm ~ 2, A total of 10200 strains, has entered the results period. It was observed that the fruit of late-maturing lines of the fruit showed stable performance, more than two months later than that of common konjak maturity, and maintained the inherent fine characters of common konjak.
