Conyza spp. é uma espécie de difícil controle, principalmente quando se encontram com maior estatura e em estádios mais avançados desenvolvimento. O estudo objetivou avaliar a eficiência controle 2,4-D colina da mistura formulada glifosato diferentes estaturas Os fatores avaliados foram três (1-2; 10-12 25-30 cm); dois herbicidas [2,4-D (EC) + (ED)]; doses destes correspondentes 0x, 1/2x, 1x, 2...

Aerification and topdressing are important cultural management practices that help prevent organic matter accumulation soil compaction in golf greens. However, these result surface disruption decreased putting quality during recovery. A 2-year study was conducted on a ‘TifEagle’ hybrid bermudagrass ( Cynodon dactylon × C. transvaalensis ) green to determine the effect of different aerification ...

In order to better understand the mechanism of molecular-beam epitaxy (MBE) growth on GaAs(OOl), itisessential to know the structure of the arsenic rich (2X 4 )/e(2X 8) surface where growth usually begins and ends. We have studied this surface with the scanning tunneling microscope (STM). The specimens were grown by MBE and arsenic capped prior to transfer to the STM. In the STM chamber the ars...

Knowledge of rangewide variation in DNA content and ploidy level may be valuable in understanding the evolutionary history of a species. Recent studies of Acacia senegal report diploids and occasional tetraploids in the Sudano-Sahelian region of sub-Saharan Africa, but nothing is known about the overall extent of DNA ploidy variation within the species. In this study, we determine the DNA conte...

This study examined fiber type-dependent differences in the regulation of protein synthesis in individual muscle fibers found within the same whole muscle. Specifically, the in vivo SUrface SEnsing of Translation (SUnSET) methodology was used to measure protein synthesis in type 1, 2A, 2X and 2B fibers of the mouse plantaris muscle, in response to food deprivation (FD), and mechanical overload ...

Putative gamete-derived progenies from two Hylocereus species, the diploid H. monacanthus and the tetraploid H. megalanthus, were studied with the dual aims to confirm their gamete origin and to evaluate their potential use as genetic resources. An additional goal was to determine the origin (allotetraploid vs. autotetraploid) of H. megalanthus by exploring morphological variations in the di-ha...
