Sorghum Bicolor L

A study on the extent and pattern of genetic variability in late-maturing sorghum [ Sorghum bicolor (L.) Moench] landraces collected from the Wello and Hararge areas of Ethiopia was conducted using random amplified polymorphic DNA (RAPD) markers for 70 individuals representing 14 populations. Four oligonucleotide primers generated a total of 55 polymorphic bands with 13–19 bands per primer and a mean of 16 bands across the 70 individuals. The value of the Shannon diversity index among the populations (0.26) and between the two regions (0.24) was low to moderate, despite the high degree of polymorphic bands per primer. The mean genetic distance (0.25) between the populations was found to be low. The low genetic variation may be due to the reduced population size of late-maturing sorghum landraces in the two regions of Ethiopia because of farmers’ decisions in the process of planting, managing, harvesting and processing their crops. Partitioning of the genetic variation into variation between and within the population revealed that 92.9% and 7.10% of the variation was found to be between and within the populations, respectively. Cluster analysis of genetic distance estimates further confirmed a low level of differentiation in late-maturing sorghum populations both between and within the regions. The implications of the results for genetic conservation purposes are discussed.

Six populations (Psen, Pns, F1, F2, BCsen, BCns) were used to estimate genetic variances for ratoon tiller regrowth in sorghum (Sorghum bicolor (L.) Moench). All data involving progeny of senescent and nonsenescent crosses were pooled for analysis using the joint scaling test. Parental lines differed significantly in tiller production. Tiller production of a ratoon sorghum crop was used as a measure of nonsenescence and this character was quantitatively inherited with additive genetic effects, with no indication of significant dominance genetic effects. The large estimates for additive genetic variation indicated that some progress could be made in selecting for tillers in a ratoon sorghum crop. However, heritability estimates were low (0.18–0.28) for number of tillers in ratooned sorghum. The selection program would probably be most successful if it were based on tiller counts after 6 wk of regrowth. Estimates concerning the number of effective factors controlling tiller number in a ratoon crop indicated that this characteristic is under the control of one major factor or chromosome segment.

Objetivou-se neste estudo quantificar a evapotranspiração real (ETr) e máxima da cultura (ETc) e os coeficientes da cultura (Kc) do consórcio palma-sorgo. O experimento foi conduzido no município de Serra Talhada, PE. O delineamento usado foi em blocos ao acaso, envolvendo cinco lâminas de irrigação (0, 25, 50, 75 e 100% da evapotranspiração de referência - ETo), sob sistema de cultivo consorciado palma-sorgo. O clone de palma forrageira utilizado foi a Orelha de Elefante Mexicana (Opuntia stricta (Haw.) Haw.) e o cultivar de sorgo, Sorghum bicolor (L.) Moench, a SF 15. O sorgo foi conduzido durante dois ciclos (planta e rebrota) compreendidos em um ciclo anual da palma. A quantificação da ETr e da ETc foi realizada através do resíduo do balanço de água no solo (BAS) a cada 14 dias, com a mensuração dos componentes hidrodinâmicos. As determinações da ETc e do Kc foram realizadas com base na lâmina de 75% da ETo. Os componentes do BAS foram submetidos à análise de regressão, sendo testados modelos polinomiais. Com exceção da variação do armazenamento de água no solo, os demais componentes hidrodinâmicos do solo cultivado sob sistema consorciado palma-sorgo respondem linearmente ao aumento de lâminas de irrigação. A evapotranspiração média diária do consórcio palma-sorgo é igual a 3,0 mm dia-1, independentemente da lâmina de irrigação. Os coeficientes do consórcio palma-sorgo são iguais a 0,40, 0,68, 0,90 e 0,52 durante as fases I, II, III e IV de emissão de cladódios.

Le changement des habitudes alimentaires au cours de ces dernières années a abouti à l’apparition des maladies dites de civilisation, parmi elles le diabète sucré. Des approches diétothérapeutiques privilégient la consommation des produits céréaliers sous la forme la plus complète possible. Ce travail a pour but de tester l’efficacité des régimes expérimentaux préparés à base des grains complets des deux céréales, le sorgho (Sorghum bicolor L.) et le seigle (Secale cereale L.), sur la correction de l’hyperglycémie et des marqueurs du stress oxydant associés au diabète chez le rat mâle Wistar. Les résultats montrent que les rats diabétiques, soumis au régime seigle pendant quatre semaines, présentent une diminution significative de la glycémie qui atteint les 53,95 % à la fin de l’expérimentation, ce qui fait que leur taux en glycémie se rapproche de celui des normoglycémiques. Le sorgho blanc présente, d’une part, une diminution significative de la peroxydation lipidique intracellulaire et, d’autre part, une augmentation de l’activité de la glutathion peroxydase, la glutathion réductase ainsi que la vitamine C. Ces approches méthodologiques peuvent, en améliorant la connaissance de l’importance des céréales (fibres alimentaires solubles et des polyphénols) dans l’évolution du diabète, aboutir à des recommandations et à une éducation nutritionnelle du diabétique.
