Modeling phyllochron in wheat and barley

Creator:: Cao, Weixing
Abstract:: An understanding of the effect of environment on phyllochron (degree-days between two successive leaves) is necessary to model cereal crop canopy growth. This study was designed to investigate the relationships of phyllochron to temperatures and daylengths in winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.). A series...

Effect of medium, fertilizer rates and transplant methods on the growth of young apple trees

Creator:: Lu, Can
Abstract:: This study compared leaf mold, bark, automobile waste and the combination of half leaf on the top and half bark on the bottom as growing media for young apple nursery stock. Although the chemical and physical analysis of leaf mold was superior to the bark, trees in leaf mold showed...

Sugar uptake, fruit growth and carbon partitioning in the strawberry

Creator:: Forney, Charles F.
Abstract:: Sinks, plant organs which depend on the import of assimilates for growth, play a central role in determining assimilate distribution patterns within the plant. The strawberry fruit is a strong sink for dry matter and its effect on carbon partitioning and assimilation in the plant as well as the mechanism...

Leaf area index and productivity in eastern Washington forests

Creator:: McCandlish, Brooks
Abstract:: The relationship between Leaf Area Index (LAI) and current stem-wood production was examined in selected stands in eastern Washington. Stands were sampled with an angle gauge (prism). LAI was estimated from sapwood area; current stem-wood production from DBH, height, and radial increment. Maximum LAI attainable on a given site has...

Stand sapwood basal area : an indicator of tree vigor

Creator:: Oren, Ram
Abstract:: The control that stand leaf area exerts upon individual tree vigor was tested on a heterogeneous, even-aged Douglas-fir stand infected by Phellinus root rot. Tree vigor, or growth efficiency ratio, was defined as the current basal area growth per unit of leaf area. Because of a close relationship between sapwood...

Competitive interactions between Douglas-fir or ponderosa pine and whiteleaf manzanita

Creator:: White, Diane E.
Abstract:: Juvenile Douglas-fir, ponderosa pine, and whiteleaf manzanita growth in southwest Oregon varied with density of co-developing manzanita and presence of herbaceous cover. Plant xylem pressure potential and stomatal conductance of each species was responsive to competition-induced depletion of soil water. Rates varied among species. The best correlations with growth usually...

Growth characteristics and site potentials of perennial grass species

Creator:: Borman, Michael M.
Abstract:: In this study I assessed the potentials of selected, established perennial grasses to maintain site occupancy in the foothills ecosystem of the Rogue River Valley of southwest Oregon which is currently dominated by a variety of annual plants. The first evaluation compared growth curves of the perennial grasses and contrasted...

The role of density and proportion in allometric equations of Douglas-fir and red alder seedlings

Creator:: Cooke, Pamela T.
Abstract:: Allometric equations are useful tools for predicting tree biomass when direct measurements are impractical. Any factor affecting plant growth can be a significant variable in allometric equations. Density and species proportion are spatial variables that influence tree growth and should be considered when developing allometric equations. This consideration is especially...
