The SeridóBelt,at the extreme northeast of Brazil,is one of the several Neoproterozoic mobile belts related to the Brasiliano/Pan-African Orogeny in Western *** lithostratigraphy of the SeridóBelt comprises basal quartzites and metaconglomerates(Equador Formation)overlain by hornblende-bearing paragneisses,calc-silicate rocks and marbles(Jucurutu Formation)and biotiteschists(SeridóFormation).We investigated the sedimentary provenance of these rocks based on an integration of compiled whole-rock geochemistry,Sm-Nd isotopes,U-Pb detrital zircon ages and a new set of whole-rock trace elements *** Formation quartzites have major and trace elements patterns that resemble cratonic sandstones,with a typical felsic provenance consistent with the isotopic composition of plutonic Archean to Paleoproterozoic basement *** proxies suggest that these rocks were deposited in fresh waters under anoxic conditions and moderate to intense weathering conditions(CIA=58–79).A shift in provenance led to an increase in intermediate-mafic sources during the deposition of the Jucurutu and Seridó*** elements from rock types in these units are nearly identical,yet they differ on the contents of some high field-strength elements(e.g.,Sc,V and Ni),which are higher in the SeridóFormation than average *** proxies show similar depositional environments,with brackish to marine conditions for the Jucurutu and Seridóformations under anoxic to euxinic *** conditions are consistently lower in the Jucurutu Formation(CIA=58–66)in comparison with the SeridóFormation(CIA=60–88).Compiled U-Pb data suggest maximum depositional ages of 633±11 Ma and 633±6 Ma for Jucurutu and Seridóformations,respectively,suggesting deposition following the ca.645–635 Ma Marinoan *** compared the geochemistry of the SeridóFormation schists with currently exposed basement rocks and showed a strong affinity with Neoproterozoic arc-related

Mini-cutting technique for Khaya anthotheca: selection of suitable IBA concentration and nutrient solution for its vegetative propagation

Journal of Forestry Research 2018年第1期29卷 73-84页

作者： Joamir Barbosa Filho Maria Angélica Di Carvalho Leandro Silva de oliveira Enéas ricardo Konzen Gilvano Ebling Brondani College of Forestry Federal University of Mato Grosso(UFMT) Institute of Agronomic Sciences Federal University of Minas Gerais (UFMG) department of Forest Sciences Federal University of Lavras (UFLA)

Khaya anthotheca is a hardwood species from Africa and recently introduced to Brazil. This species yields high-quality wood for diverse applications, but little has been done toward an effective propagation method for large-scale production in nurseries. We evaluated the effects of different concentrations of macro and micronutrients（i.e., 100, 50 and 25% of the concentration of a referenced solution） combined with indole-3-butyric acid（IBA） at 0 and 2 g L-1 on the survival rate of mini-stumps and the survival and adventitious rooting of K. anthotheca mini-cuttings. The mini-stumps were grown from a source of seeds imported from Ghana, West Africa. The ministumps survived at a high rate（97%）. Consistently high shoot yields were obtained from the mini-stumps（average of 1.8 per mini-stump）. High survival percentage of minicuttings and adventitious rooting were observed when solutions with 100 and 50% of the nutrients concentration were combined with 2 g L-1 IBA. Histological sections analyzed through optical microscopy indicated the tissues from mini-cutting stems were juvenile, which might have stimulated adventitious rooting. These results have important implications for further work aimed at establishing propagation strategies for K. anthotheca, which are of prime importance for assisting breeding programs of this species.
