Twenty-three students of HORT 2212: Herbaceous Ornamental Plants divided into five teams, each selecting one of the ground beds at the television studio gardens of Oklahoma Gardening to design with the aid of MacDraw II and Macintosh computers. The team approach promoted cooperative learning, where those who were skilled in design worked cooperatively with those individuals more skilled at developing the theme gardens' cultural pamphlets. This project encouraged individual students to develop various communication skills to support their team's thematic garden-visual, in the form of a CAD plot of the garden design; written, in the form of a garden pamphlet; and telecommunication, in the form of Oklahoma Gardening television segments.
The students and OBGA Ambassadors started the seeds and, then, planted the gardens, resulting in a very practical experience. This design and installation project not only prepared students for the cooperative efforts that they are likely to encounter in the ornamental horticulture and landscape design and maintenance industries, but also imparted pride in their work, which was viewed by over 150,000 television viewers and visitors weekly.
Abstract
The cultivation of a wide range of ornamental plants in a closed hydrosolaric greenhouse was studied. The hydrosolaric greenhouse was composed of a solar energy harvesting system and a hydroponic system. Energy collected by the greenhouse air from the sun during the day was conserved in the growth solution, which released it during the night. This system was able to maintain the air temperature 6 C above the outdoor temperature during the night. Relative humidity ranged between 85 and 100%, thus providing a favorable environment for tropical foliage plants. Philodendron bipinnatifidum Schott, Gardenia jasminoides Ellis, Ficus benjamina L., F. lyrata Warb., Anthurium andreanum Lind and Brassaia actinophylla Endl. produced under this system were of excellent quality.
objectives of our experiments were to: 1) compare the irrigation capturing ability of some commonly grown ornamental plant species exhibiting a range of growth habits; 2) evaluate the effect that plant size, container diameter, and container spacing have on
Three-river Plain, the key agriculture and animal husbandry developing region of China is located in the northeast part of Heilongjiang province. There were rich resources of wild ornamental plants in Three-river Plain. 134 species of those were investigated belonging to 54 families. 35 were woody plants and 99 herbaceous. The domestication and cultivation of several plants with high decorative value were studied and briefed as follows: (1) Vibrunnum sargenti Koehne propagates by seeds beginning to blossom in 3 years and by rhizome. The plants grown in the plain are subject to insect pests: (2) Sambucus buergeriana Blume propagates by seeds after sand cultivation for 4-6 months and begins to blossom in the next year; (3) Acanthopanax Senticocus (tupr. et (maxim) harmes propagates by seeds, shoot layering and root cutting. The germination of seeds is lower and the shoot layering is best. It grows slowly in the white clay soil, (4) Hemerocallis midendorffii Tranty. et Mey, propagates by seeds and suckers and blossoms in the next year, growing well in the plain; (5) Ostrich fern (Matteuccia struthiopteris (L.) Todaro) propagates by spore. The spore grows to sporophyte in 70-90 days after sowing and the sporophyte grows to sporophyll in 4 years.
Abstract
Relative water use patterns for 12 species of container-grown ornamental plants, areca palm (Chrysalidocarpus lutescens Wendl.), ficus (Ficus benjamina L.), gumbo-limbo [Bursera simaruba (L.) Sarg.], parlor palm (Chamaedorea elegans Mart.), paurotis palm [Acoelorrhaphe wrightii (Griseb. + Wendl.) Wendl. ex Becc.], philodendron (Philodendron selloum Koch), pigeon plum (Coccoloba diversifolia Jacq.), schefflera (Brassaia actinophylla Endl.), seagrape [Coccoloba uvifera (L.) L.], silver buttonwood (Conocarpus erectus var. sericeus Fors, ex DC.), silver palm [Coccothrinax argentata (Jacq.) Bailey], and West Indian mahogany [Swietenia mahagoni (L.) Jacq.] were measured by comparison of actual water consumption with growth rates and predicted potential evapotranspiration rates. Growth rates as determined by the change in size index over time were used to characterize species as slow, moderate, or fast-growing. The lowest relative water demand was seen in the slow-growing species. Highest relative water demand occurred in the moderate and fast-growing species. Certain moderate and fast-growing plants such as West Indian mahogany, philodendron, and pigeon plum exhibited relative water demand rates not significantly different from the slow-growing species. Monthly potential evapotranspiration rates were closely related to actual irrigation demand levels in all 12 species.
