Genetic stability in synthetic wheat accessions: cytogenetic evaluation as a support in breeding programs. Author(s): FRIZON, P.; BRAMMER, S. P.; LIMA, M. I. P. M.; CASTRO, R. L. de; DEUNER, C. C. Repository: BDPA Publication year: 2017
A differential phenotypic expression of a divergent spindle mutation in interspecific Brachiaria hybrids. Author(s): FELISMINO, M. F.; PAGLIARINI, M. S.; VALLE, C. B. do Several mutations are known to alter the normal progression of meiosis and can be correlated with defects in microtubule distribution. The dv mutation affects the spindle organization and chromosomes... ... Repository: BDPA Publication year: 2008
Morpho-agronomic, cytogenetic and molecular characterization of synthetic wheat accessions as a potential germplasm for plant breeding. Author(s): BRAMMER, S. P.; CARGNIN, A.; KIIHL, T. A. M.; RESENDE, T. T. de; CASASSOLA, A.; CECCON, C. C. Synthetic hexaploid wheat (AABBDD) is produced by using the tetraploid Triticum turgidum var. durum (AABB) and the diploid Aegilops tauschii (DD) as parents. This cross has allowed genetic variability... ... Repository: BDPA Publication year: 2021
Cytogenetic analysis of wheat seeds submitted to artificial aging stress. Author(s): MENEZES, V. O.; LOPES, S. J.; TEDESCO, S. B.; HENNING, F. A.; ZEN, H. D.; HENNING, L. M. M. Several studies have been developed to understand the physiology of seed deterioration, however, the initial steps of the deterioration process are not completely clear. Seed vigor and viability losse... ... Repository: BDPA Publication year: 2014
Deltamethrin-induced nuclear erythrocyte alteration and damage to the gills and liver of Colossoma macropomum. Author(s): CUNHA, F. dos S.; SOUSA, N. da C.; SANTOS, R. F. B.; MENESES, J. O.; COUTO, M. V. S. do; SENA FILHO, J. G. de; CARNEIRO, P. C. F.; MARIA, A. N.; FUJIMOTO, R. Y. Deltamethrin is one of the most commonly used pyrethroids in the world, and it has a high toxic potential, mainly on aquatic organism. Thus, the purpose of this study was to evaluate LC50 values of de... ... Repository: BDPA Publication year: 2018
2n Gamete formation in the genus Brachiaria (Poaceae: Paniceae). Author(s): GALLO, P. H; MICHELETTI, P. L.; BOLDRINI, K. R.; RISSO-PASCOLOTTO, C.; PAGLIARINI, M. S.; VALLE, C. B. do Microsporogenesis of several Brachiaria species of the Brazilian collection at Embrapa Beef Cattle has been analyzed in detail. This paper reports abnormal cytokinesis in three accessions of three dif... ... Repository: BDPA Publication year: 2007
Meiotic arrest compromises pollen fertility in an interspecific hybrid between Brachiaria ruziziensis x Brachiaria decumbens (Poaceae: Paniceae). Author(s): MENDES-BONATO, A. B.; PAGLIARINI, M. S.; VALLE, C. B. do Microsporogenesis was analyzed in an interspecific hybrid between an artificially tetraploidized sexual accession of Brachiaria ruziziensis (2n=4x=36) and a natural apomictic tetraploid accession of B... ... Repository: BDPA Publication year: 2007
Effects of sublethal and realistic concentrations of the commercial herbicide atrazine in Pacu (Piaractus mesopotamicus): long-term exposure and recovery assays. Author(s): DELCORSO, M. C.; PAIVA, P. P. de; GRIGOLETO, M. R. P.; QUEIROZ, S. C. do N. de; COLLARES-BUZATO, C. B.; ARANA, S. Abstract: Background and Aim: The commercial formulations of the herbicide atrazine (cATZ) are widely employed in Brazilian agriculture, and, as a consequence, ATZ has been found at levels above that... ...

Meiotic behavior of interspecific hybrids between artificially tetraploidized sexual Brachiaria ruziziensis and tetraploid apomictic B. brizantha (Poaceae). Author(s): FELISMINO, M. F.; PAGLIARINI, M. S.; VALLE, C. B. do ABSTRACT -The meiotic behavior of four interspecific promising hybrids was evaluated by conventional cytological methods. The female genitors were two artificially tetraploidized sexual accessions of... ... Repository: BDPA Publication year: 2010
Microsporogenesis in Brachiaria bovonei (Chiov.) Robyns and B. subulifolia (Mez) Clayton (Poaceae). Author(s): RISSO-PASCOTTO, C.; PAGLIARINI, M. S.; VALLE, C. B. do ABSTRACT - Some African species of Brachiaria have been introduced into the Americas and became the most important forage for pastures in the tropics. New cultivars can be obtained either from direct... ... Repository: BDPA Publication year: 2009
