The application of ectomycorrhizal (ECM) fungi on forest nursery production is regarded as part of good management practice. However, before employing large scale inoculations in a nursery the interaction between ECM symbionts, growth substrate and fertilisation input should be studied to select the most suitable nursery practices for promoting plant growth and ECM colonisation. In this study, ...

Among the subgroups of agricultural workers, nursery workers have previously been identified as a group at high risk for occupational skin disease. Review of available surveillance information on nursery skin illnesses has also demonstrated that provocation patch testing is performed in less than 1% of the reported cases. We tested reactions to a battery of pesticides, plants, and the standard ...

The purposes of this study were to determine if phenotypic selection for in vitro dry matter digestibility (IVDMD) could be used to improve the IVDMD for switchgrass tPanicum virgatum L.) and to obtain heritability estimates of IVDMD in switchgrass. In 1973 a selection nursery of over 2,200 plants was established with transplanted seedlings of two similar Nebraska experimental strains. In 1974 ...

This proceedings is a compilation of 33 papers that were presented at the regional meetings of the forest and conservation nursery associations in the United States in 2002. The joint meeting of the Southern Forest Nursery Association and the Northeastern Forest and Conservation Nursery Association was held at the DoubleTree Hotel and Conference Center in Gainesville, Florida on July 15 to 18. ...

Turfgrasses play an important role in improving the environment atmosphere, and functional values modern cities. Soil-borne diseases are one of most significant constraints to ornamental nursery outputs. Among several fungi isolated from roots turfgrass plants collectedfrom different land scape gardens located at Alexandria , Cairo, Giza,

BACKGROUND Mixture models (MM) can be used to describe mixed stocks considering three sets of parameters: the total number of contributing sources, their chemical baseline signatures and their mixing proportions. When all nursery sources have been previously identified and sampled for juvenile fish to produce baseline nursery-signatures, mixing proportions are the only unknown set of parameters...

Acacia mearnsii De Wild. is one of the most widely cultivated forest species in Brazil. Despite its importance, studies on breeding strategies for this are scarce. Therefore, aim study was to evaluate progeny and develop early selection A. mearnsii. Individuals half-sib progenies were classified according their genotypic value selected based relative performance. The additive effect only signif...

© 2003 Canadian Medical Association or its licensors A lthough nursery rhymes are considered an integral part of childhood, the medical events experienced by their characters have never been documented. Several popular nursery rhymes portray head injuries as inevitable events that do not require medical follow-up. In this paper, we document the prevalence of head injuries in nursery rhymes and ...

A protocol for micrografting shoot tips harvested from in vitro shoot cultures directly to transplanted rootstock plants in the greenhouse was developed. Shoot tips of the apple (Malus domestica) cultivars Golden Delicious, Granny Smith and Fuji clone, Nagafu12, were harvested, stored in a water bath then prepared for grafting by cutting the stem immediately below the tip into a wedge shape lea...
