一个芸香科属间嫁接嵌合体的拉丁名称:+Citroponcirus‘Hormish’

An Intergeneric Grafting Chimera Name:+ Citroponcirus 'Hormish'

摘要:

柑桔属(CitrusL.)和枳属(PoncirusRaf.)属间嫁接嵌合体是1986年从福建省连城县莒溪镇一个专业户果园的芦柑(CitrusreticulataBlanco)嫁接于枳(Poncirustrifoliata(L.)Raf.)的2 a生植株发生冻害后由嫁接口蘖芽产生变异获得的。枝条有单身复叶、二出复叶和三出复叶,一些枝条出现三出复叶枳枝,表现出芦柑和枳的嵌合；幼果密被茸毛,为枳的性状,成熟果实为芦柑形态并具有芦柑风味,产生一部分为枳一部分为芦柑的嵌合果;果实汁胞以橙红色为主,兼有少量淡黄色汁胞和橙黄嵌合汁胞。依据《国际栽培植物命名法规》,芸香科柑桔属和枳属属间嫁接嵌合体拉丁名称的属名是柑桔属和枳属的属名合并建立的新“属名”,定名为+枳合芦属(+Citroponcirus),栽培品种加词采用这个嫁接嵌合体发现者的人名表示,这个属间嫁接嵌合体的拉丁名称是+Citroponcirus‘Hormish’；以公式表示为Citrusreticulata+Poncirustrifoliata。在施文格(Swingle)柑桔分类系统中,+Citroponcirus‘Hormish’是目前世界上芸香科嫁接嵌合体中唯一的属间嫁接嵌合体。

Abstract:

An intergeneric graft chimera between Citrus reticulata 'Ponkan' and Poncirus trifoliata (L.) Raf. was found in a farmholding orchard in Juxi Town, Liancheng County, Fujian Province, in 1986, which was obtained from the buds appeared after freezing damage in graft union of 2-year-old seedling of cultivar 'Ponkan' grafted on the stock of Poncirus. The graft chimera is named as + Citroponcirus 'Hormish'which has unifoliate, bifoliolate and trifoliolate leaves in some branches, and trifoliolate in other branches, showing a chimera of the two species. Young fruits are pubescent as those in Poncirus. Mature fruits are similar to 'Ponkan' in shape and in flavour, but some have the appearance of chimera character of both Poncirus and 'Ponkan'. Juicy pulp is mostly orange-red in colour with a few yellowish pulp. This report aims to give and disscuss the name of this chimera which is unique in Rutaceae.
