Modeling seed dispersal distances: implications for transgenic Pinus taeda.
Predicting forest-tree seed dispersal across a landscape is useful for estimating gene flow from genetically engineered (GE) or transgenic trees. The question of biocontainment has yet to be resolved, although field-trial permits for transgenic forest trees are on the rise. Most current field trials in the United States occur in the Southeast where Pinus taeda L., an indigenous species, is the ...
متن کاملexploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
Introgression between Pinus taeda L. and Pinus echinata Mill
Loblolly pine (Pinus taeda L.) and shortleaf pine (Pinus echinata Mill.) have widely overlapping geographic ranges. Hybridization between the two species has interested tree breeders for a long time. Morphologically, the two pine species are different. The needles of loblolly pine are 6 to 9 inches long, usually with three yellow-green needles per fascicle; but shortleaf pine needles are 3 to 5...
متن کاملNutrient use and uptake in Pinus taeda.
We quantified nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) content, use (nutrient amount for one growth year), retranslocation (nutrients recycled before foliage senescence), uptake (use minus retranslocation), volume production per unit of uptake and fertilizer-uptake efficiency (percent applied taken up) in a 2 x 2 (nutrient and water) factorial experiment repl...
متن کاملDetermination of viability of Phytophthora capsici oospores with the tetrazolium bromide staining test versus a plasmolysis method.
BACKGROUND Oospores are the most persistent propagules of Phytophthora capsici. The viability of oospores is determined by staining methods such as the tetrazolium bromide (MTT) test. OBJECTIVES The aim was to assess the MTT test and a plasmolysis method for their utility in determining viability of oospores of P. capsici. METHODS For either procedure the reactions of non-treated (viable) a...
