Harn, Chang Yawl (Chonpuk U., Iri, Korea)-Studies on the interspecific crossing of FORSYTHIA genus. Kor. Jour. Bot. 4(1)1~8 1961: Interspecific crossing of two species, F. saxatilis and F. Koreana, was carried out in order to make clear the segregation ratio of style length, mode of fertility, the fertility of F1 generation, dioecism, and other taxonomic question, the result of which being summarized as follows: 1) Style length is segregated into 1:1 ratio. 2) The behaviro of fertility in the legitimate and illegitimate unions between the different species is exactly like that in the two dimorphic forms of the same species. 3) The mode of fertility between the long and short style of the F1 generation also follows that of the heterostyle plants. 4) No difficulties or irregularities are observed in the interspecific crossing and the F1's fertility. 5) In F1 generation exceedingly high morphological and physiological variations are observed. 6) The short style individual is well fertilized and sets seed when legitimately combined. The insistence that the short style is male, this genus being dioecious, is groundless. 7) Among F1 individuals, are observed a few dwarf-types with tiny and weak vegetative and reproductive organs. 8) The two species used behave in many ways like the different styles of the same species. |
