Abstract

This study explores the dynamics of vegetable grafting, focusing on bell pepper hybrid MS and various Capsicum spp. rootstocks. The experiment delves into seed germination, seedling growth parameters and grafting outcomes. MS hybrid demonstrates swift germination and robust seedling growth, attributed to hybrid vigor. Rootstocks CRS-22 and CRS-24 exhibit delayed germination and slower growth. MS grafted on CRS-1, CRS-2, CRS-11, and CRS-15 rootstocks showcases superior graft success, while CRS-22 and CRS-24 combinations exhibit lower success rates. Graft combinations with CRS-14 and CRS-21 demonstrate lower graft failure rates, emphasizing compatibility. Stem girth, leaf count, and plant height variations highlight the influence of rootstock selection. The study's insights contribute to optimizing grafting practices for enhanced bell pepper cultivation, emphasizing the crucial role of seed germination and seedling growth parameters in achieving successful graft unions. The chilli rootstocks such as CRS-1, CRS-2, CRS-11, CRS-14, CRS-15 and CRS-21 has shown more than 70 per cent of graft success indicating a higher compatibility with the bell pepper hybrid MS.

Conclusion

In summary, the study underscores the distinct germination and early growth characteristics among various rootstock seeds in bell pepper cultivation. The bell pepper hybrid MS exhibited rapid germination and seedling growth attributed to hybrid vigor, while rootstock seedlings of Capsicum frutescence species, such as CRS-22, CRS-12, CRS-21, and CRS-13, displayed prolonged germination periods and slower growth rates. The choice of rootstock significantly influenced parameters such as stem girth, leaf count, and plant height. Grafting success rates varied among different rootstock combinations, with CRS-1, CRS-2, CRS-11, and CRS-15 demonstrating higher success rates, whereas CRS-22 and CRS-24 exhibited comparatively lower success rates possibly due to incompatibility. Additionally, graft combinations involving CRS-14 and CRS-21 showed lower graft failure rates, emphasizing the importance of rootstock-scion compatibility. The study provides valuable insights for optimizing rootstock selection and grafting practices in bell pepper cultivation to enhance overall plant development and yield.
