Graft chimeras

Spontaneous graft chimeras

• Anno 1674 : 'Bizzarria' orange
  A florentine gardener grafted a scion of sour orange on to a seedling stock of citron. The scion did not take succesfully, but a bud arising out of the callus developing on the stock grew up into bizarre tree. On the same plant, there were leaves, flowers, and fruit, identical with the orange or with the citron, and there were compound fruits with the two kinds blended together or sectored in various ways.
• Anno 1825 : + Laburnocytisius adamii
  Adam, a nurseryman from Vitry near Paris inserted a shield from the bark of a broom into a stock of common laburnum. The bud lay dormant for a year, and then grew with a flourish of buds and shoots, one of which grew more upright and vigorous, and with larger leaves then the usual broom. It was distributed throughout Europe as + Laburnocytisius adamii. The tree proved to be somewhat unstable, and branches spontaneously reverted to both parental species in their flowers and leaves.
• Anno 1904 : + Pyrocydonia
  Spontaneus graft chimera of Pyrus communis and Cydonia oblonga

Synthethic graft chimeras

Within the family Solanaceae a number of graft chimeras were synthesized. Examples are:

• Lycopersicum pimpinellifolium + Solanum nigrum (Brabec, 1960)
• Solanum tuberosum + Lycopersicum esculentum (Jorgensen 1927)
• Nicotiana tabacum + Nicotiana glauca (Marcotriguano and Gouin, 1994)
