油菜中内源赤霉素嫁接转移研究(英文)

Studies of Graft Transfer of Endogenous Gibberilic Acids in Rapeseed (B. napus)

在温室条件下 ,将未春化的油菜接穗分别嫁接在已春化和未春化油菜砧木上 ,结果已春化油菜砧木上的接穗植株很快开花 ,而未春化砧木上的接穗植株不能开花 .其主要原因是与已春化油菜砧木内源赤霉素含量高 ,并传递到接穗有关 .

The scions of the unvermalized rapeseed plants were grafted into the stocks of the vernalized and unvernalized rapeseed plants under green house conditions. As a result, flowering was soon observed in the scions grafted into the vernalized stocks, but not in those grafted into the unvernalized stocks. This phenomenon was explained due to the existence of a high level of gibberellin in the vernalized rapeseed plants,that was transferred to the grafted scions.
