Evaluation of Honey as a Rooting Adjuvant for Cutting Propagation of Three Common Nursery Crops Plant propagation is a labor-intensive process in the nursery and greenhouse industry, with labor accounting for 41.4% of expenditures in 2019—$4.8 billion of the $11.6 billion total. Labor availability remains a critical issue, and current methods of applying root-promoting compounds to cuttings of... Evaluation of Surfactants for use in One-time Foliar Auxin Applications in the Propagation of Woody Ornamentals Use of foliar applications are increasing in the nursery and greenhouse industries. However, previous research has shown that insufficient auxin is being absorbed or translocated to the site of action. Addition of surfactants to foliar applications of auxin may help with the absorption and transloca... UVC (254 nm) and Far UVC (222 nm) irradiation affects in vitro growth of Colletotrichum sp. isolates and their infection of detached strawberry leaves. Various alternatives are being developed to reduce or replace chemicals for plant disease control. We conducted laboratory studies to evaluate the effect of conventional UVC (245 nm) or FarUVC (222 nm) irradiation on growth of strawberry anthracnose pathogens in culture and on the disease response f... Combining high throughput phenotyping and multivariate analysis to assess fruit quality traits in southern highbush blueberry (V. corymbosum interspecific hybrids) germplasm collection Breeding blueberry cultivars with enhanced fruit quality requires simple, accurate and cost-effective assays to select individuals from segregating populations. In this study, berry diameter, berry weight, firmness, pH, total polyphenol, total acids, D- glucose, D-fructose, total glucose, and total ... 'USDA-Spiers' rabbiteye blueberry U*SDA-Spiers’ is a new hexaploid blueberry (Vaccinium hybrid ) developed by the United States Department of Agriculture-Agricultural Research Service and resulted from crosses among diverse blueberry germplasm and species including V. virgatum (rabbiteye blueberry) with V. constablei, V. corymbosu... Evaluation of one-time applications of foliar applied auxin co-applied with surfactant for use in commercial cutting propagation Use of foliar auxin applications are increasing in the nursery and greenhouse industry. However, previous research has shown that insufficient auxin is absorbed or translocated to the site of action when foliar auxin applications are used. It is theorized that adding surfactants to foliar applicatio... Intensity of supplemental greenhouse lighting affects strawberry plant growth, response to anthracnose infection, and growth of Colletotrichum pathogens in culture. The effect of supplemental lighting on plant growth and response to anthracnose disease of strawberries was evaluated in two greenhouse trials, and their effect on the growth of strawberry anthracnose pathogens was evaluated in the laboratory. The objective of the greenhouse trials was to determine ... Nuclear DNA content and chromosome number determination in a Sahel medicinal plant, Combretum micranthum G. Don Combretum micranthum G. Don, also known as kinkéliba, is native to West Africa where the plant grows wild as a shrub, liana, or tree and is valued for its numerous attributes including health and nutritional benefits. Despite this, genetic information commensurate to its economic value is lacking. T... Determination of genome size and chromosome number of a Ziziphus species (Z. mauritiana Lam.) from eastern Senegal Ziziphus mauritiana Lam. is a widespread shrub or tree of the Sahel region where it grows wild and is used for various purposes including nutrition, medicine, and firewood. Current domestication programs focus on using the local species as rootstock for the improved imported Asian cultivars to provi... Micropropagation of Hibiscus moscheutos L. ‘Luna White’: Effect of growth regulators and explants on nuclear DNA content and ploidy stability of regenerants Hibiscus moscheutos L., also known as hardy hibiscus, is valued for its medicinal and ornamental attributes. It is usually propagated via seeds or cuttings. The purpose of this investigation was to develop a dependable micropropagation for H. moscheutos ‘Luna White’. To that end, the effect of four... Effect of LED, UV-B, and fluorescent supplemental greenhouse lights on strawberry plant growth and response to infection by the anthracnose pathogen, Colletotrichum gloeosporioides Supplemental lighting is frequently used to extend day length for strawberries (Fragaria ×ananassa Duch.) grown in greenhouses and high tunnels; however, information is limited on the effect of these lights on disease development. We evaluated the effect of six supplemental light treatments [red, bl... New chromosome number and cytomolecular characterization of the African Baobab (Adansonia digitata L.) – "The Tree of Life" The African baobab (Adansonia digitata L.), also referred to as the “Tree of Life”, is a long-lived, majestic, and multipurpose tree of sub-Saharan Africa. Internationally, a growing demand for baobab products in the food, pharmaceutical and cosmetics industries has been observed. Given this, there ... Effect of LED, UV-B, and fluorescent supplemental lights on plant growth and fruit quality of strawberries grown in a greenhouse and on their infection by Colletotrichum spp. Supplemental lighting is used to extend daylength for strawberries grown in greenhouses and high tunnels; however, information is limited on the effect of these lights on disease development and pathogen growth. We evaluated the effect of 6 supplemental light treatments (red, blue, white, and combi... Determination of nuclear DNA content, ploidy, and FISH location of ribosomal DNA in Hibiscus hamabo Hibiscus hamabo Sieb.et Zucc, a deciduous shrub or tree, is an important semi-mangrove plant with golden yellow flowers. The plant is also cultivated for its fiber and grown as an ornamental. It is halophytic and considered one of the best afforestation trees used in reclamation programs in urban an... Characterization and pathogenicity of stem blight complex isolates associated with stem blight disease on Vaccinium species Species of Botryosphaeria and Neofusicoccum are major pathogens of blueberry worldwide. Accurate identification of these species is essential for developing effective management practices. A multigene sequencing strategy was used to distinguish between six isolates collected from two different regio... High-frequency somatic embryogenesis, nuclear DNA estimation of milkweed species (Asclepias latifolia, A. speciosa, and A. subverticillata), and genome size stability of regenerants. A high-frequency somatic embryogenesis was developed for three Asclepias species, A. latifolia (broadleaf milkweed), A. speciosa (showy milkweed), and A. subverticillata (horsetail milkweed) using gibberellic (GA3) and the amino acid L-proline. A somatic embryo initiation medium consisting of MS sal... Hedychium Essential Oils: Composition and Uses Hedychium genus, composed of about 80 species, are multipurpose plants that are generally used as ornamental plants because of their showy, diverse, and scented colorful flowers. Hedychium extracts are widely used in traditional medicine to treat a multitude of ailments while their essential oils h... ‘Muffin Man’ an edible ornamental rabbiteye blueberry The rabbiteye blueberry (Vaccinium virgatum Aiton 2n = 6x = 72) is commercially important in the southeastern United States because of its adaptability to prevalent biotic and abiotic stresses. There is a growing interest in edible landscaping as alternative to conventional landscapes. ‘Muffin Man’ ... Reaction of different vaccinium species to the blueberry leaf rust pathogen Thekopsora minima Blueberry leaf rust caused by Thekopsora minima, is a serious threat to blueberry production. To investigate the host range and characterize new sources of resistance, 15 southern highbush accessions, two interspecific hybrids (Vaccinium spp.), and accessions from five diploid Vaccinium species were... Variation in nuclear DNA content and chromosome numbers in blueberry Commercial blueberry production in the U.S. relies on cultivars derived from combinations of different blueberry species. Interspecific hybridization continues to be a vital strategy for blueberry breeding, especially in regards to improving abiotic and biotic stress tolerance to expand the range of...
