The characteristics of the grafted "Improved Sweet Orange" seedlings showed various segregations, such as "yellow fresh color of Aurantium type","chimaera of red or yellow fresh color of Aurantium type","red fresh color of Aurantium type","chimaera fruit of 1Vlicroacrumen type" and "variant of Microacrumen type", in the vegetative progenies found so far.

一种是把植物的嫁接变异视为&嫁接杂种&；另一种看法则认为除非两个嫁接亲本体细胞的核真正融合在一起，成为染色体数加倍的新个体，才能称为&嫁接杂种&，而这种&嫁接杂种&至今还未见到有可靠的报道。目前所见到的有关嫁接变异的报道，实际上是一些&嫁接嵌合体&，即两个嫁接亲本体细胞的机械嵌合。

The results are as follow:The diploid chromosome number of Taihe Silkies was 2n=78,the basic number of chromosome arms was AF=90 and the sex chromosome type was ZZ/ZW.According to the measured relative length,arm ratio and centromeric index,the first 10 pairs of macro-chromosomes are described as follows:No.1 ,9 and Z,W chromosomes were metacentrics,No.2,4,7 were submetacentrics,and No.3,6,8,10 were telocentrics.Studies on Taihe Silkies′ G-band showed that the first 10 pairs of macro-chromosomes can be divided into 29 zones and 190 bands.
