Hawaii has no native pines, but many species have been introduced as ornamental or potential timber trees. These species have been planted in environments that differ greatly from their natural habitat. This paper describes how the coordinated seasonal cycle of growth and flowering has been influenced by the climatic conditions these pines have encountered in Hawaii. Hawaii has no native pines,...

It is well known that occupational exposure to pollens of flowering ornamental plants may elicit rhinoconjunctivitis, asthma, and contact urticaria (1). However, it was not until the 1980s that a foliage decorative plant, weeping fig (Ficus benjamina), was recognized as an important cause of occupational immediate mucosal and skin reactions, and, to a lesser degree, of similar symptoms in atopi...

The antibacterial activity of eight products marketed for the therapy and prophylaxis of diseases of ornamental fishes was tested. The products contained erythromycin, neomycin, a nitrofuran, penicillin, sulfa compounds, streptomycin, or tetracycline. When used at the concentration recommended by the manufacturer, the products failed to inhibit the growth of bacterial species known to be potent...

Syngonium podophyllum Schott, commonly referred to as Nephthytis, in commercial chan nels ranks fourth in economic importance in the ornamental foliage industry of Florida and has a sales value of approximately $350,000 annu ally. Of the relatively few diseases which affect Syngonium, a leaf spot caused by Cephalospo rium dnnamomeum Linn has been observed to occur with not uncommon frequency an...

parasitic diseases are harmful and limiting factors in breeding and rearing ornamental fish industry. in this study, 400 apparently healthy ornamental fishes from five species (each species 80 specimens) including: goldfish (carassius auratus), guppy (poecilia reticulate), angelfish (pterophyllum scalare), discus (symphsodon discus) and sailfin mollies (poecilia latipinna) was obtained from a l...

INTRODUCTION Ornamental grasses and sedges have a long history. Are they a new crop? Yes, both old and new at the same time. And a crop that has had a dramatic impact on the appearance of our developed landscape, on the work of landscape architects and planting designers, on nursery producers and landscape managers, and on researchers! Millions and millions of units of grasses and sedges are cu...

Portugal produces a great diversity of ornamental stones. Besides the internationally known white and pink marbles, also light cream limestones are produced, as well as grey, yellow and pink granites, and dark grey slates. A first exercise is presented on the evaluation of the available resources of ornamental stones in the whole Portuguese territory. The results show a total availability of 41...

A total of 25 aphid species were collected from 49 ornamental plant species in São Carlos-São Paulo, Brazil; 12 aphids were monophagous, four oligophagous and nine polyphagous. A total of 58 aphid-plant associations are recorded, 43 unknown from Brazil. Eucarazzia elegans (Ferrari, 1872) (Aphididae: Aphidinae: Macrosiphini) is recorded for the first time from Brazil, and Nectandra megapotamica ...

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...
