koelreuteria elegans, popularly known as “flame gold” is an ornamental tree. in vitro callus induction and regeneration from various explants (eaf segments and cotyledonary leaf) were studied on modified ms medium. the highest callus induction rate (80%) and multiplication was obtained in 2 mg/l 2,4-d from leaf segments. calli transferred in 1.5 mg/l bap resulted in efficient shoot regeneration...

A discussion of the agronomic theory of placing plant nutrients in the root zone of ornamental trees and plants by high pressure hydraulic injection. Definite beneficial effects of deep root injection feeding by high pressure in jection of plant nutrients have been observed in tree and ornamental plant installation and main tenance. The response outperformed conventional surface applications of...

Human has a duty to preserve the nature, preserving the plant is one of the examples. This research emphasis on ornamental plant that has functionality not only as ornament plant but also as a medicinal plant. Purpose of this research is to find the best of the particular feature extraction components from several wavelet transformations. It consists of Daubechies, Dyadic, and Dualtree complex ...

Pine needle scale, Chionaspis pinifoliae (Fitch), is a pest of many species of conifers in urban habitats and Christmas tree farms. We found that the scale was abundant in impoverished habitats, such as ornamental landscapes, and scarce in more natural, park-like habitats. Rates of parasitism were highest in impoverished habitats, suggesting that parasitoids were not effective in suppressing sc...

Potential spread of the Asian longhorned beetle (Anoplophora glabripennis Motschulsky) (Coleoptera: Cerambycidae: Lamiinae: Lamiini) (ALB) in the United States is dependent upon its rates of reproduction and dispersal, particularly among host tree species that it encounters within suitable climatic regions. Therefore, the goal of this study was to measure the reproductive potential of ALB on th...

The East Palaearctic seed beetle Bruchidius terrenus (Coleoptera: Chrysomelidae: Bruchinae) is recorded for the first time to the Bulgarian fauna. Larvae of the bruchid infest mature seeds of introduced mimosa Albizia julibrissin (Fabacea), an ornamental tree in many countries. The level of damage on seeds caused by bruchid larvae was examined.

The erythrina gall wasp (EGW), believed native to Africa, is a recently described species and now serious invasive pest of Erythrina (coral trees) in tropical and subtropical locales. Erythrina are favored ornamental and landscape trees, as well as native members of threatened ecosystems. The EGW is a tiny, highly mobile, highly invasive wasp that deforms (galls) host trees causing severe defol...
