Exogenous Treatments to Enhance Splice-Grafted Watermelon Survival

This study evaluated the use of splice grafting as a propagation strategy for watermelon. In experiment 1, treatments consisted sucrose, antitranspirant A, B, auxin (indole-3-butyric acid (IBA)) at two concentrations (10 and 20 mg·L−1), plus water control. The survival (%) splice-grafted watermelon plants differed due to number days after treatment (p < 0.0001, both). At 21 grafting, treated with sucrose A 10 mg·L−1 had 90% 88% survival, respectively, whereas graft was 18% water. Experiment 2 included three top performing from 1 control treatment, applied both root-intact root-excised rootstocks. There significant difference in root treatments, exogenous all). grafted 11% lower compared plants. Plants 87% 86% 14% survival. external application rootstock seedlings does not appear be cost-effective; however, other products should evaluated.
