聽講有d十字基因相對穩定
插葉都得
詳情唔太清楚
You are right, some 十字花 will have 穩定基因 to stay 十字 even propagated from leaf cuttings.
The word "chimera" is a "living structure or organism in which the tissues are of varied genetic origin" (quoted from Rob's violet website). Actually, "chimera" is not equal to 十字花, this is not a good translation.
Like Rob's Lucky Penny, Rob's Lucky Number, they are "chimera" but their flowers are not 十字. It is their leaf patterns which is a wanted feature which cannot be propagated from leaf cutting. |
