Abstract :

The present study evaluates propagation by cuttings and transplantation of Bambusa vulgaris Schrad. at the University of Kinshasa, observing growth stages to collect data useful for the restoration of soils degraded by gully erosion and the provision of environmental services useful to society. The methodology consisted of observation and experimentation through growth measurements (diameter and height) in the nursery after 3 months, and transplantation (6 months after). The results show that out of 10,000 cuttings, 9,300 managed to recover, representing a recovery rate of 93%. The control group also showed a high recovery rate of 93.7%. Analysis of recovery rates reveals significant variations over time, peaking on day 12. Regarding height growth, the plants showed a notable average growth, with the control group reaching 95.13 cm compared to 91.02 cm for the samples on a varied substrate. The experiment also focused on diameter enlargement, with significant results showing an increase over time. By transplanting 300 B. vulgaris seedlings using the green wall technique, the study focused on spear emergence, height growth and root elongation. The results show a significant positive correlation between spear emergence and time, with a total of 5 spears after 180 days. Analysis of height development and root elongation revealed statistically significant differences between groups and over time. In conclusion, this study confirms that Bambusa vulgaris reproduces by cuttings and can be transplanted effectively on various substrates, thus constituting a fundamental reference in the fight against erosion, in the fight against climate change and in contributing to the resilience of communities in the Democratic Republic of Congo through nature-based solutions.
