毛花猕猴桃‘赣猕6号’主要生物学特性研究

Biological Characteristics of Actinidia eriantha ’Ganmi 6’

为了对‘赣猕6号’的推广及制定合理栽培管理措施提供参考依据,试验采用田间观测与室内测试相结合的试验方法对其主要生物学特性进行观测研究。结果表明,在江西省奉新地区,伤流期在2月中旬,初花期在5月上旬,谢花期在5月下旬,果实成熟期在10月下旬,为晚熟品种;根系浅,肉质,以须根为主;花单性,二歧聚伞花序,平均单株花量为550~675朵,花红色,极具观赏性;以中果枝和长果枝结果为主,分别占66.0%与28.5%;果实为长圆柱形,平均单果重72.5 g,最大单果重96 g;果实的Vc、总糖、可滴定酸以及SSC平均含量分别为829.23 mg/100g、11.31%、1.32%和14.42%。毛花猕猴桃‘赣猕6号’生物学性状遗传稳定,具有较高的发展前景。

To provide references for formulating cultivation and management measures of‘Ganmi 6’,the main biological characteristics were observed by field observation and laboratory testing.The results showed that the bleeding period was in mid-February,the initial flowering period was in early May,the full-bloom period was in late May,the fruit ripening period was in late October,and‘Ganmi 6’was a late maturing variety in Fengxin area of Jiangxi Province.‘Ganmi 6’had shallow and succulent roots,and the main roots were fibrous roots.Flowers were unisexual and typical dichasium,the average number of flowers per plant was 550-675,the flower was red and highly ornamental.The fruiting branches were medium and long fruit branch and accounted for 66.0%and 28.5%,respectively.The fruit was long cylindrical,the average fruit weight was 72.5 g,and the maximum single fruit weight was 96 g.The average content of Vc,total sugar,titratable acid and SSC was829.23 mg/100 g,11.31%,1.32%and 14.42%,respectively.The biological characteristics of‘Ganmi 6’are genetically stable and the variety has a high development prospect.
