Seasonal Fine Root Carbohydrate Relations of Plantation Loblolly Pine ,- After Thinning

چکیده
Loblolly pine (Pinus tueda L.) occurs naturally on soils that are frequently low in fertility and water availability (Allen et al., 1990; Schultz 1997). Despite these limitations, this species maintains a high level of productivity on most sites (Schultz, 1997). Knowledge of plantation loblolly pine root system growth and physiology is needed to understand how this species is adapted to soil resource limitations, and how management can be used to favor root system function. The fine root dynamics of mature conifers is modal with a distinct

Seasonal Fine-root Carbohydrate and Growth Relations of Plantation Loblolly Pine after Thinning and Fertilization’
In 1989, lwo levels each of stand density and fertilization were established in an 8-year-old loblolly pine (Pinus faeda L.) plantation. In March 1995, treatments were reapplied, and root elongation and carbohydrate concentrations were monitored for 2 years. Our objective was to evaluate relationships between seasonal root growth and carbohydrate concentration in response to thinning and fertil...

h 1989, two levels each of stand density and fertilization were factorially established in an 8-year-old loblolly pine plantation on a P-deficient site. Levels of stand density were nonthinned at 2,732 trees per hectare and thinned at 721 trees per hectare. Fertilizer levels were none or application of 150 kilograms P plus 135 kilograms N per hectare. In 1994, stand basal areas of the nonthinne...

In 1989, we established two replications of two fertilization treatments in a 10-year-old loblolly pine (Pinus taeda L.) plantation. Between March and September 1993, branch internode and needle fascicle expansion in the upper and lower third of crowns were measured weekly on three south-facing branches of each of four trees, and new root initiation and elongation were measured at 10-day interv...
متن کاملWhole-tree and forest floor removal from a loblolly pine plantation have no effect on forest floor CO2 efflux 10 years after harvest
Intensive management of southern pine plantations has yielded multifold increases in productivity over the last half century. The process of harvesting merchantable material and preparing a site for planting can lead to a considerable loss of organic matter. Intensively managed stands may experience more frequent disturbance as rotations decrease in length, exposing the stands to conditions tha...
متن کاملSeasonal Ectomycorrhizal Fungal Biomass Development on Loblolly Pine (pr'nus Faeda L.) Seedlings
Ergosterol, a membrane sterol found in fungi but not in plants, was used to estimate live mycelial biomass in ectomycorrhizae. Loblolly pine (Pinus tueda L.) seeds were sown in April 1993 and grown with standard nursery culture practices. Correlations between total seedling ergosterol and visual assessment of mycorrhizal colonization were high during July and August but low as ectomycorrhizal d...
