Cutting polarity

POLARITY AND ROOT REGENERATION

Marking the base

The apex and base of a cutting occupy different positionsTowards the apexSevered surface

Record the orientation before dividing a long stem. This applies especially to fragments without an apex. [Fleischer and Schütz 1978] [Druege et al. 2019]

Wound healing

The cut surface remains above the substrate during healingWell-ventilated position

Limiting water loss and forming a barrier at the wound precede heavy watering. Assess the time needed by the condition of the tissues. [Fleischer and Schütz 1978] [Druege et al. 2019]

Adventitious roots

Adventitious roots develop in the basal part of the cuttingOriginal orientationShallow planting

Once rooting begins, the need for water and oxygen in the substrate increases. New roots do not prove that a cutting is completely healthy. [Fleischer and Schütz 1978] [Druege et al. 2019]

The diagram shows a typical stem cutting placed upright. Horizontal rooting is sometimes possible, but is not a rule for all cacti. [Fleischer and Schütz 1978] [Druege et al. 2019]

A new treatment of the topic in rozmnazanie4. The physiology of adventitious roots follows Druege et al. 2019 and archival sources. [Fleischer and Schütz 1978] [Druege et al. 2019]
