dc.typeThesis
dcterms.abstractNehe (Lipochaeta integrifolia) is a Hawai‘i endemic sprawling species that has been used as a native groundcover but has not been evaluated for use in hanging baskets. While morphological diversity exists within the species, evaluating collections from different locations/populations in terms of propagation success (with or without rooting hormone) and performance under hanging basket conditions have not been conducted. In this study, three nehe accessions (Koko Head, Makapu‘u, and South Point) were screened for propagation/rooting success under mist conditions and were evaluated under hanging basket conditions in terms of growth habit, canopy cover, leaf, internode and flower characteristics, and flowering frequency. Results indicated that the three accessions significantly varied in their rooting responses at each experimental run. The application of 3,000 ppm indole-3-butryic acid on apical stem cuttings did not improve rooting characteristics across accessions. Differences in rooting responses between experimental runs may be due to Plasmopara sphagneticolae, a new downy mildew disease reported in nehe. Morphological characterization under hanging basket conditions indicated that the three accessions can be differentiated in terms of leaf shape, flower diameter and peduncle length. Makapu‘u and Koko Head differed in terms of branch numbers (main, secondary, tertiary, and total) and canopy densities between two to six months after potting. Flowering frequencies also varied between the two accessions from two to ten months after potting. Overall, Koko Head was identified as the most suitable accession for hanging baskets due to its small canopy, high flower numbers, frequent flowering, and short inactive flowering period.
