Final diagnosis


Genetic abnormalities

This young leaf shows irregularly distributed discolorations on the blade.  Be careful not to confuse these symptoms with those of certain viral diseases.  <b> Genetic anomaly </b> (chimera)
Detail of discolorations visible on the limbus.  <b> Genetic anomaly </b> (chimera)
On the underside of the blade of this young leaf, irregular discolorations are less visible.  <b> Genetic anomaly </b> (chimera)
Several leaves of this vine have more or less discolored areas of the blade.  <b> Genetic anomaly </b> (chimera)
On this sheet, it can be seen that the yellowing of the blade mainly concerns rather geometric sectors delimited by the veins.  <b> Genetic anomaly </b> (Chimera 2)
The leaf at the bottom is weakly affected by a genetic defect.  A small proportion of its blade has turned yellow.  It is not the same for the sheet located above.  <b> Genetic anomaly </b> (chimera)
