Resumo: | The objective of this study was to characterize morfoagronomicamente buffel grass accesses the active germplasm bank (BAG) of Cenchrus of the Embrapa Semiárido checking the variability and efficiency of characters in carrier two consecutive cuts. We used 26 hits and 4 buffel grass cultivars in randomized blocks with three replications and with plot nine plants per access, taking as the central portion useful plant in the plot. The evaluations were performed after two cuts of the aerial part of Buffel grass, each evaluation was performed 90 days after each cut. The characterization of the accessions was based on 15 quantitative and qualitative morphological descriptors. Quantitative descriptors were submitted to analysis of individual and combined variance, considering the two cuts of treatment and then applied the Scott-Knott test at 5% probability. Qualitative descriptors were submitted to descriptive analysis. For divergence analyzes both quantitative and qualitative descriptors were grouped using the methods of Tocher and UPGMA from the Mahalanobis distance (D2). In addition, a dendrogram and calculated the relative importance of characters for the divergence. In the combined analysis, the effects of access and cutting were significant for almost all the features. This result indicates genetic heterogeneity among the accessions and the felling indicates mainly differences in management culture conditions and growth rate of each access in each mowing season. It was also observed significant effect of genotype x environment interaction at 1% probability for three descriptors (NPT, and LIN QIN) and other descriptors (APL, ECO, COF, LFO and CIN) these effects were not significant. The accessions were separated into two groups, the first consisting of 25 hits and 4 cultivars and the second composed of the access 138. The number of tillers / shoot, followed by number of inflorescence and color of the seeds were the most relevant characters in separation of access. |

Foram utilizados 26 acessos e quatro cultivares de capim buffel em delineamento em blocos ao acaso com três repetições com parcela de nove plantas por acesso, tomando como parcela útil a planta central dentro da parcela. As avaliações foram realizadas após dois cortes da parte aérea do capim buffel, cada avaliação foi realizada 90 dias após cada corte. A caracterização dos acessos foi realizada com base em 15 descritores morfoagronômicos quantitativos e qualitativos. Os descritores quantitativos foram submetidos à análise de variância univariada individual e conjunta, considerando os dois cortes dos tratamentos e, em seguida, aplicado o teste de Scott-Knott a 5% de probabilidade. Os descritores qualitativos foram submetidos a análise descritiva. Para as análises de divergência tanto descritores quantitativos quanto qualitativos foram agrupados utilizando-se os métodos de Tocher e UPGMA, a partir da distância generalizada de Mahalanobis (D2). Foi estabelecido também um dendograma e calculada a importância relativa dos caracteres para a divergência. Na análise conjunta, os efeitos de acesso e corte foram significativos para quase todas as características. Esse resultado indica heterogeneidade genética entre os acessos e quanto ao corte indica, principalmente, diferenças nas condições de manejo da cultura e da velocidade de crescimento de cada acesso em cada época de corte. Também foi observado efeito significativo da interação genótipos x ambientes ao nível de 1% de probabilidade para três descritores (NPT, LIN e QIN) e para os demais descritores (APL, ECO, COF, LFO e CIN) estes efeitos não foram significativos. Os acessos foram separados em dois grandes grupos, o primeiro composto por 25 acessos e quatro cultivares e o segundo composto apenas pelo acesso 138. O número de perfilhos/touceira, seguida por quantidade de inflorescência e cor das sementes foram os caracteres de maior relevância na separação dos acessos.Submitted by Ricardo Cedraz Duque Moliterno (ricardo.moliterno@uefs.br) on 2016-07-13T23:53:47Z No. of bitstreams: 1 Dissertação final_completa_pdf.pdf: 1029289 bytes, checksum: 67d8eb9bd97c05071808a15be37032a8 (MD5)Made available in DSpace on 2016-07-13T23:53:47Z (GMT).

The objective of this study was to characterize morfoagronomicamente buffel grass accesses the active germplasm bank (BAG) of Cenchrus of the Embrapa Semiárido checking the variability and efficiency of characters in carrier two consecutive cuts. We used 26 hits and 4 buffel grass cultivars in randomized blocks with three replications and with plot nine plants per access, taking as the central portion useful plant in the plot. The evaluations were performed after two cuts of the aerial part of Buffel grass, each evaluation was performed 90 days after each cut. The characterization of the accessions was based on 15 quantitative and qualitative morphological descriptors. Quantitative descriptors were submitted to analysis of individual and combined variance, considering the two cuts of treatment and then applied the Scott-Knott test at 5% probability. Qualitative descriptors were submitted to descriptive analysis. For divergence analyzes both quantitative and qualitative descriptors were grouped using the methods of Tocher and UPGMA from the Mahalanobis distance (D2). In addition, a dendrogram and calculated the relative importance of characters for the divergence. In the combined analysis, the effects of access and cutting were significant for almost all the features. This result indicates genetic heterogeneity among the accessions and the felling indicates mainly differences in management culture conditions and growth rate of each access in each mowing season. It was also observed significant effect of genotype x environment interaction at 1% probability for three descriptors (NPT, and LIN QIN) and other descriptors (APL, ECO, COF, LFO and CIN) these effects were not significant. The accessions were separated into two groups, the first consisting of 25 hits and 4 cultivars and the second composed of the access 138. The number of tillers / shoot, followed by number of inflorescence and color of the seeds were the most relevant characters in separation of access. |
