English Abstract

The concern about the propagation of native shrubs is increasing; many ecologically and economically important species that are difficult to propagate by seeds have been under study by nursery propagators.

In Kurdistan region-Iraq, Rhus coriaria L.

- Anacardiaceae or Sumac is the only native species of the genus Rhus in Iraq; with considerable ethnobotany and ecological values.

This species is difficult to be propagated sexually and asexually via shoot cuttings.

This study analyzed the potential of producing Sumac seedlings using root cuttings.

Effects of cutting size (1cm > diameter >1cm, length 7-15cm,), and exogenous indole-3-butyric acid IBA hormone pretreatment (0, 2000, 3000 and 4000 ppm) on rooting were studied in three replicates under outdoor nursery conditions from March – October of 2014.

Rooting percentage %, number of roots, root length, shoot length, number of branches and number of leaves of newly generated cuttings statistically analyzed in a complete randomized block design (CRBD).

The results of the study showed that cutting diameter, length, and IBA application and the interactions between them significantly affected all the measured traits.

For optimal rooting and producing good quality seedlings, the findings recommended thinner but longer root cutting (diameter<1 cm; 15cm) treated with 4000 ppm IBA.
