Analysis of seedling growth characteristics between two greenhouse cover types, old fiberglass and new polycarbonate, shows significant differences in height and sturdiness coefficients in ponderosa pine (Pinus ponderosa) seedlings. Three rates of nitrogen (N) application (20, 40, and 60 mg) indicate that seedling growth will increase under both cover types, but may cause a reduction in seedlin...

PROBLEM: Eelgrass (Zostera marina) seeds are being used in a variety of both smalland large-scale restoration activities and have been successfully used to initiate recovery of eelgrass in the Virginia seaside coastal lagoons, which lost eelgrass in the 1930s ‘wasting disease’ pandemic (Orth et al. 2006a). However, a major bottleneck with the use of seeds has been the relatively low rate of see...

Seedling morphology of 210 species (173 trees and 37 lianas) was studied from a community perspective to identify major patterns of seedling functional types in a Mexican rain forest. Five types of seedlings were distinguished: cryptocotylar with reserve storage or absorption cotyledons (epigeal [CER] and hypogeal [CHR]), phanerocotylar epigeal, either with photosynthetic cotyledons (PEF) or wi...

Vermicompost is an excellent organic fertilizer, but the application of vermicompost in fragrant rice production has not yet been reported. Seedling nursery important component production. The present study firstly applied through raising. seedlings three cultivars were raised matrix with different rations (the treatment without was taken as control), and growth parameters physiological charact...

rots (Great Plains); seedling blight (Great Plains). Indian ricegrass {Oryzopsis hymenoides) : Seedling blight (far West) ; common root rot and crown rot (far West) ; rhizoctonia rot (scattered) ; snow molds (Pacific Northwest); seed rots (general); root necrosis and crown rots (far West). Kentucky bluegrass {Poa pratensis): Dollar spot (Northeast) ; brown patch (general); foot rot, Helminthosp...

Researchers have obtained conflicting results about the role of prosocial motivation in persistence, performance, and productivity. To resolve this discrepancy, I draw on self-determination theory, proposing that prosocial motivation is most likely to predict these outcomes when it is accompanied by intrinsic motivation. Two field studies support the hypothesis that intrinsic motivation moderat...

Although core self-evaluations have been linked to higher job performance, research has shown variability in the strength of this relationship. We propose that high core self-evaluations are more likely to increase job performance for other-oriented employees, who tend to anticipate feelings of guilt and gratitude. We tested these hypotheses across 3 field studies using different operationaliza...
