Abstract

This research investigated the graft compatibility of various Capsicum spp. rootstocks with the popular bell pepper hybrid Massilia RZ F1. Grafting is a technique that combines desirable fruit characteristics of a scion with the disease resistance and stress tolerance of a rootstock, contributing to increased yield and improved quality. The study focused on 25 rootstocks, including different Capsicum species, evaluating their compatibility and productivity. Significant variations were observed in seed germination times and seedling growth parameters among the rootstocks. CRS-23 and Massilia RZ F1 exhibited quick germination, showcasing seed vigour. Graft success varied across combinations, with high success observed in combinations involving CRS-1, CRS-2, CRS-6, CRS-8, CRS-11, CRS-12, CRS-13, CRS-14, CRS-15, and CRS-21. Compatibility was reflected in scion girth, rootstock girth, and graft union girth measurements at 15 days after grafting. This study emphasizes the importance of selecting compatible rootstock-scion combinations for successful grafting, highlighting potential options for improved germination, graft success, and desirable growth traits in grafted bell pepper plants.

Conclusion

In summary, this experiment suggests that the choice of rootstock and grafting combination can significantly influence the success of the grafting process, as well as the subsequent growth and development of the grafted seedlings. It appears that CRS-23 and MS are promising rootstock and scion options for quick germination and grafting. Additionally, the combination of MS with various rootstocks, such as CRS-1, CRS-2, and others, results in high graft success percentages, which is crucial for successful grafting. The selection of the appropriate rootstock is also essential for achieving desirable girth measurements in grafted seedlings.
