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 کاملAssociation genetics in Pinus taeda L. I. Wood property traits.
Genetic association is a powerful method for dissecting complex adaptive traits due to (i) fine-scale mapping resulting from historical recombination, (ii) wide coverage of phenotypic and genotypic variation within a single experiment, and (iii) the simultaneous discovery of loci and alleles. In this article, genetic association among single nucleotide polymorphisms (58 SNPs) from 20 wood- and ...
متن کاملMicropropagation of Pinus taeda L. via axillary buds
Introduction Pinus taeda stands for productivity and quality of its timber [1]. Researches using biotechnology are of great importance and have been applied to the improvement of its timber and plantation [2]. The main method of Pinus propagation is by seeds, once the minicuttings depends on the season of the year or depends of juvenile material [3-5]. Thus, researches on micropropagation of Pi...
متن کاملMicropropagation of Pinus taeda L. from Juvenile Material
The purpose of this study was to develop a protocol for the micropropagation of Pinus taeda from juvenile material. Apical shoots and nodal segments were inoculated into MS, DCR or WV medium. After 90 days, the explants were transferred to WV5 medium supplemented or not with 6-benzyladenine (BA) (2.0 μM) in order to induce multiple shoot formation. For root induction, a medium composed of water...
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...
