Studies with homeopathie on seed germination of native forest species are scarce, regardless of its potential as low impact technology. Therefore, the objective of this study was to evaluate the use of homeopathic medications in different dynamizations in the seed germination of yellow ipe. The experimental design was completely randomized with three replications, in a factorial scheme with the three medicines in five dynamizations, totaling 16 treatments with the control consisting of distilled water. The medications used were Calcarea carbonica, Carbo vegetabilis and Silicea. The mediations were applied in of 6, 12, 30, 100 and 200 centesimals hahnemanianas (CH) dynamizations. Regarding germination percentage and speed of germination index the medicament...

STRUCTURAL EVALUATION OF DAMAGE CAUSED BY HERBICIDE CLOMAZONE IN LEAVES OF ARBORESCENT SPECIES NATIVE TO BRAZIL
Provedor de dados: Planta Daninha
Autores: CABRAL,C.M.; SANTOS,J.B.; FERREIRA,E.A.; COSTA,S.S.D.; DALVI,V.C.; FRANCINO,D.M.T.
ABSTRACT Herbicide clomazone is highly soluble in water, which increases the risk of leaching, resulting in contamination of sources of groundwater and waterways, affecting non-target organisms, with possible degradation of riparian areas. The objective of this work was to investigate the possible anatomical modifications of the leaf tissue of twelve arborescent species native to Brazil grown in soil contaminated by clomazone, in order to microscopically characterize leaf damage caused by the herbicide, and investigate whether the structural damage precedes visible damage. Through micro morphometrics, the thickness and the area occupied by the tissues were measured in a cross section of the leaves of the forest species: adaxial and abaxial epidermis,...

Evapotranspiration and water sensitivity of Amazonian yellow ipe seedlings under different shading conditions
Provedor de dados: Revista Brasileira de Engenharia Agrícola e Ambiental
Autores: Keffer,Josiane F.; Silva,Cátia C. da; Souza,Adilson P. de; Silva,Andréa C. da; Bouvié,Luana; Dias,Thaíse K. R.
ABSTRACT The scarcity of information on the agroclimatic and ecophysiological requirements of forest species, especially in the initial phase, limits the production of quality seedlings, the planning and optimization of nurseries. The potential evapotranspiration, crop coefficients (kc) and water sensitivity coefficients (ky) of Amazonian yellow ipe seedlings were determined under different shading conditions and levels of water replacement to the substrate, in the dry period (July to October 2016), in the Cerrado-Amazon Rainforest transition region of the Mato Grosso state, Brazil. The experiment evaluated the full sun and black polyester nets with 35, 50, 65 and 80% shading, and the levels of water replacement to the substrate of 25, 50, 75 and 100% ETc...

Post pollination events in a self-sterile hexaploid monoembryonic lineage of Handroanthus serratifolius (Vahl) S. Grose (Bignoniaceae)
Provedor de dados: Acta Botanica Brasilica
Autores: Alves,Mariana Ferreira; Bittencourt Júnior,Nelson Sabino; Oliveira,Paulo Eugênio; Sampaio,Diana Salles.
ABSTRACT In diploid late-acting self-incompatible (LSI) species of Bignoniaceae, self-pollinated pistils show a marked delay in ovule penetration by pollen tubes, followed by delayed, but otherwise normal, initial stages of endosperm development and subsequent pistil abscission. Most polyploid species of Bignoniaceae are apomictic and set selfed fruits with viable polyembryonic seeds carrying adventitious embryos. Handroanthus serratifolius is a polyploid species with sporophytic apomictic individuals that produce polyembryonic seeds after either self- or cross-pollination, and other LSI individuals that produce exclusively monoembryionic seeds. Our aim was to determine whether self-sterility events in the latter are similar to those observed in other...
