Peach scion

Prunus persica (L.) Batsch

The peach scion is characterized by high sensitivity to physiological compatibility with the rootstock, where genetic affinity and the capacity for efficient assimilate transport through the graft union serve as critical factors.

In the reference 12 varieties crop Peach, where this is mentioned in the description.

In peaches, the issue of scion-rootstock incompatibility manifests through specific disorders such as pitting, starvation of rootstock tissues, and translocation incompatibility. The latter can result in delayed tree mortality due to the disruption of nutrient transport, even when the graft union appears visually successful.

Peach compatibility is largely determined by the specific genotype of the rootstock clone. The most stable results are achieved using peach seedlings or specialized peach-almond hybrids, whereas the use of plum or Nanking cherry rootstocks is associated with risks of long-term breakage or physiological dysfunction.

Modern assessment of scion quality and its union with the rootstock involves monitoring biochemical markers, such as phenolic compound content, RNA/DNA ratios, and phloem functionality. This allows for the detection of latent forms of incompatibility that do not manifest during the early stages of vegetation in the nursery.
