由于大多数柑桔栽培品种的多胚性,因此,在许多国家仍用实生繁殖柑桔苗。这种方法沿用了许多世纪,而中国人大约在公元前1000年就已经知道用嫁接方法繁殖果树(Hartmann等。1975)。现在,在热带国家还能见到柑桔实生树,但新定植的树,除小规模外,一般都采用芽接苗。嫁接苗有很多优点,但也有某些不足之处(见表1)。

Due to the multi-embryogenic nature of most citrus cultivars, citrus shoots are still reproduced in many countries. This method has been used for centuries, and the Chinese knew about grafting fruit trees by grafting around about 1000 BC (Hartmann et al., 1975). Citrus real trees can now be seen in tropical countries, but newly planted trees, except for small ones, are usually sprouted. Grafted seedlings have many advantages, but there are also some shortcomings (see Table 1).
