In March 2011, anthracnose symptoms were observed on stems of Dracaena sanderiana as imported ornamental plant in Gorgan, Golestan province (NE Iran). According to the Farr et al. (2006) the pathogenic fungus were identified as Colletotrichum dracaenophilum D.F. Farr & M.E. Palm. 

Ornamental plants are constantly being improved by new technologies and cultivation systems to provide new, high-quality plant material for one of the most demanding markets in horticulture sector [...]

This study evaluates the performance of horizontal subsurface flow constructed wetland (HSSF-CW) for the removal of chlorinated resin and fatty acids (RFAs) from pulp and paper mill wastewater. The dimensions of the treatment system were 3.5 m x 1.5 m x 0.28 m with surface area of 5.25 m, filled with fine sand and gravel. The cell was planted with an ornamental plant species Canna indica. The r...

Japanese cultivated gentians (Gentiana triflora, G. scabra and their hybrids), some of the most important ornamental flowers in Japan, have vivid blue flowers that accumulate polyacylated anthocyanins such as gentiodelphin. To breed attractive flower colors in Japanese gentians, our research group has been studying the molecular mechanisms that control flower pigmentation. Flavonoids, including...

An efficient in vitro plant regeneration protocol was developed for Chrysanthemum morifolium, an ornamental plant. Nodal segments were used as explants in the present experiment. The explants were cultured onto Murashige & Skoog’s (MS) nutrient medium containing plant growth regulators (cytokinins or auxins) with various combinations and concentrations for the study. Maximum percentage (93.33%)...

Nature of Work: Commercial production and management of ornamental groundcovers is especially difficult due to the cyclic nature of market demand. During peak periods, production cannot keep pace with demand due to many species possessing strong apical dominance resulting in few cuttings per stock plant (3). Secondly, vining plants held during the slack market periods become entwined and requir...

Oct./Dec. 1994 4(4) populations (at least once every 5 years). 2) Focus surveys on cultivars shown to be promising sources of taxol and taxanes. 3) Continue to sample clippings yields annually for plants more than 3 years old. 4) Study the potential for harvesting other plant organs and whole plants for taxol along with clippings. Questions to be answered include: a) What would be the optimum p...

There are very few case reports in literature of J. curcas poisoning. Previously grown as an ornamental plant; it is presently being cultivated on a large scale for its seed oil, which is used as biodiesel. This has brought this plant in close vicinity to the human population, exposing them to the chance ingestion. We are presenting clinical and biochemical profile of eight children with J. cur...

Understanding plant's defense mechanisms and their response to biotic stresses is of fundamental meaning for the development of resistant crop varieties and more productive agriculture. The Brassica genus involves a large variety of economically important species and cultivars used as vegetable source, oilseeds, forage and ornamental. Damage caused by pathogens attack affects negatively various...
