VEGETATIVE PROPAGATION VIA CUTTINGS OF THE MOROCCAN EUPHRATES POPLAR (Populus euphratica Oliv.).....

From China to North Africa, the Euphrates poplar (Populus euphratica Olivier) can be found. It only covers a few tiny places in Morocco that are vulnerable to extreme environmental stress (aridity, salinity, heat). In Morocco, there is a lack of documentation on simple vegetative propagation procedures that nursery employees can use. The goal of this research is to build a cuttings-based operational approach. Ait Atmane population, located between Er-Riche and Er-Rachidia in Morocco's south-central region, was examined for dormant and lignified sets (length: 50 to 80 cm, diameter: 8.72 2.12 mm). A factorial experimental design was used to examine the hormonal influence of 1 percent indole butyric acid (IBA) and the growing medium on sets rooted.

After 2.5 months of culture, the rooting rate of surviving sets varied between 92.5 and 100%, with no significant effect of the growing media or hormone therapy. Hormonal therapy increased the number of roots per set substantially. It ranged from 25.5 to 23.9 with hormone treatment, compared between 14.0 and 16.7 with no treatment. Root development was considerably boosted by using organic growing media. Long and short root sets are substantially more common on organic growing medium (55.4 percent and 65.8%, respectively) than on mineral growing medium (23.7 percent and 37.8%, respectively). After hormone treatment, however, 18.4 percent of the sets revealed necrosis at their bases. On IBA-treated sets grown on mineral growing medium, mortality was 52.5 percent, compared to just 5.3 percent in organic growing medium. On both types of growing medium, the mortality rate of non-IBA treated sets was less than 1.3 percent. The rate of live set bud burst varied significantly between 80.3 and 98.8%, and was slightly greater without hormone therapy.

Cuttings of Euphrates poplar can be done in marginal locations to help this plant thrive in the face of climate change. To choose efficient and resistant clones to environmental challenges, however, clonal variability research is required.
