Cultivation

Citrus scion

Citrus L.

A citrus scion is a varietal shoot or bud used to accelerate the onset of fruiting and preserve varietal characteristics. The high plasticity of these species allows them to be grafted onto various rootstocks, including Poncirus trifoliata, to modify crown habit and growth vigor.

In the reference 8 varieties crop Citrus, where this is mentioned in the description.

For citrus scions, shoots with a thickness of at least 3 mm and firm leaves are suitable; these leaves are often shortened to reduce transpiration. The success of graft union formation critically depends on maintaining high humidity during the post-operative period, which is necessary for callus development and the connection of cambial layers.

The interaction between scion and rootstock in citrus is highly pronounced: the cultivar can influence root system development, while the rootstock affects flowering time, cold hardiness, and crown habit. Grafting dwarf forms, such as kumquat, onto vigorous rootstocks is frequently practiced to create decorative container specimens.
