Resistance to pod shattering (shatter resistance) is a target trait for global rapeseed (canola, Brassica napus L.), improvement programs to minimise grain loss in the mature standing crop, and during windrowing and mechanical harvest. We describe the genetic basis of natural variation for shatter resistance in B. napus and show that several quantitative trait loci (QTL) control this trait. To ...
The study used time studies and cost analysis to assess potential economic benefits from site preparation reductions resulting producing coarse woody harvesting residue (CWHR) for bioenergy. In contrast, previous have predominantly anecdotal estimates of costs.The was performed in a recently clearfelled 15-year-old plantation Eucalyptus globulus (Labill) Tasmania, Australia. area consisted the ...
Four containerized deciduous ornamental shrubs [deutzia (Deutzia gracilis L.), silverleaf dogwood (Cornus nlba 'Elegantissima'), red-osier dogwood (Cornus sericea L.), and ninebark (Physocarpirs optilifolius L.)] were grown during each of two separate growing seasons using 12 different immature (nonaged) composts as media (year one, 12 weeks from start of windrowing; year two, 16-weeks) and als...
Meeting the reporting requirements of Kyoto Protocol has focused attention on potential forests in sustainably sequestering carbon (C) to mitigate effects rising levels atmospheric CO2. Much uncertainty remains concerning ultimate effect management such sequestration effects. The woody debris (WD) and other deadwood stocks is an example a intervention with scope affecting source-sink dynamics f...

This study was conducted to determine if the Agricultural Policy/Environmental Extender (APEX) model could reasonably replicate the effects of silvicultural practices on streamflow and loading of sediments and nutrients. APEX was modified to enhance factors associated with forestry conditions such as rainfall interception by canopy, litter, subsurface flow, nutrient movement, and routing enrich...
Background: Chorionic villus sampling refers to a procedure in which small samples of placenta are obtained for prenatal genetic diagnosis, generally in the first trimester of pregnancy in 11 weeks till 13 weeks+6 days. This procedure provides prenatal diagnosis in pregnancy. Amniocentesis is a technique for windrowing amniotic fluid from the uterine cavity using a needle via a trans abdominal ...
A common study design has been used at 13 locat ions across the South to examine loblol ly pine (Pinus taeda L.) plantations established using four vegetation control treatments after mechanical site preparat ion: (a) No Control , (b) Woody Control , (c) Herbaceous Control for 4 yr , and (d) Total Control . This research, the Compet i t ion Omission Moni toring Project (COMP), is moni toring bo...
