Sorghum Bicolor L

Endosperm transfer cells mainly occur in the epithelial layer of the endosperm and transport the nutrient unloaded by the maternal vascular tissue. They have wall ingrowths that can facilitate solute transportation. Here we report our further investigation of endosperm transfer cells in sorghum (Sorghum bicolor L. Moench). We observed endosperm transfer cells, embryo, and endosperm with different kinds of microscopes. Our experimental results showed that the distribution and configuration of endosperm transfer cells were fit for solute transportation, and they had a tight relationship with the embryo and endosperm.

Wooding and Northcote (1965), Gunning, Pate, and Briarty (1968), Gunning and Pate (1969), and Pate and Gunning (1969) have drawn attention recently to the presence of cells with wall ingrowths in a number of sites in plants at which one might expect short-distance transport of considerable quantities of solutes. Gunning and Pate (1969) suggested that these cells be called "transfer cells" and surveyed their distribution in the leaves of a large sample of Angiosperms. These cells have not been found in the leaves of any grasses, and they have been demonstrated in the Gramineae only in the embryo sac of maize (Diboll 1968). In this paper, transfer cells are illustrated in the vascular tissue at the coleoptilar node in wheat, and the possible functions of these cells at this site are discussed.

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.
