BACKGROUND Oral language skills in the preschool and early school years are critical to educational success and provide the foundations for the later development of reading comprehension. METHODS In a randomized controlled trial, 180 children from 15 UK nursery schools (n = 12 from each setting; M(age) = 4;0) were randomly allocated to receive a 30-week oral language intervention or to a wait...
Thirty-three social isolates were selected from four nursery school populations according to teacher ratings and behavioral samples obtained by trained Os. In a 2 X 2 factorial design, half of the children viewed a 23-min. modeling film depicting appropriate social behavior, while the other half viewed a control film. Half of the subjects in each film condition then received social reinforcemen...
Phytophthora ramorum (Oomycetes) is an emerging plant pathogen in forests in southwestern Oregon (Curry County). Moreover, since 2003 it has been repeatedly isolated from plants in Oregon nurseries. In this study, we analysed the genetic diversity of the P. ramorum population in Oregon from 2001 to 2004 by using microsatellites. A total of 323 isolates (272 from the infested forest; 51 from nur...
A multiple cloning technique was developed and successfully implemented commercially. This technique is derived from the so-called Frolich technique, which is used as a standard by various nurseries world-wide. This technique implies the positioning of 55 ml micro containers over the multiple etiolated shoots (one per shoot), which developed simultaneously and consecutively from the so called n...
For plant breeding and growth monitoring, accurate measurements of plant structure parameters are very crucial. We have, therefore, developed a high efficiency Multi-Camera Photography (MCP) system combining Multi-View Stereovision (MVS) with the Structure from Motion (SfM) algorithm. In this paper, we measured six variables of nursery paprika plants and investigated the accuracy of 3D models r...
plant tissue culture refers to growing and multiplication of cells, tissues and organs of plants on defined solid or liquid media under aseptic and controlled environment. micropropagation allows rapid production of high quality, disease-free and uniform planting material. the micropropagation of high quality planting materials of ornamentals, and forest and fruit trees has created new opportun...
Nursery grown seedlings of Pinus virginiana with infection by Pisolithus tinctorius (Pt) versus seedlings with naturally occurring mycorrhizae were used in greenhouse experiments to determine the influence of mycorrhizae on manganese and zinc uptake and distribution in seedlings. Unamended Pt mycorrhizal seedlings and those treated with 48.0 mg Mn/pot over a 2-week period accumulated significan...
This study examined the emissions produced during the pre-farm, farm and post-farm phases of the production cycle of raspberries and giant American whortleberries (blueberries) cultivated in one of the best-adapted areas in northern Italy. The pre-farm phase included the greenhouse gas emissions from the production of plants in the nursery and the transportation of the plants to the production ...
