Abstract

The genus Secale (Poaceae, Triticeae) was described first by Linnaeus. Based on the latest taxonomic treatment the genus contains three species, four subspecies and two varieties. Secale taxa are naturally occurring in Mediterranean areas, Eastern Europe to central Asia and South Africa. This study concerns the evaluation of taxonomic value of morphological characters and phenetic among Secale taxa in Iran. Our statistical analyses were done using the software STATISTICA. The resulting data matrix used for cluster analysis and Factor analysis. The results of this study showed that there is no diagnostic morphological character among the studied populations of Secale. The homogeneity of the morphological characters can be caused by gene flow and hybridization in this taxon, limited the taxonomic value of such traits. Based on the results of this study it can be concluded that there is a little possibility for effective separation of Secale species based on morphological characters. In the present study, the liver of 10 normal fish was studied macroscopically and microscopically. Section of tissues were made by routine paraffin embedding method and stained with H&E, PAS and Weigret's Iron Haematoxylin techniques. Macroscopic results showed that the liver is situated in cranial part of abdominal cavity and consisted of two thick and wide lobes (left and right), with a long thin process extended from each lobe. The processes were joined together. Microscopic results showed that the liver encapsulated by a thin serosa. The lobulation was not seen in the liver clearly. Parenchyma of the liver consisted of central vein, hepatic cords and sinusoids. Pancreas tissue was penetrated into the liver along with portal vein. Pancreas tissue consisted of serous cell clusters (exocrine tissue), which were arranged around a central vein. The serous cells had a euchromatin nucleus in basal portion, and their basal cytoplasm was basophilic, but the apical cytoplasm contained eosinophilic zymogenic granules. A few pancreatic islets were seen in H&E staining and only 2 types of cells were recognizable; A or a cells with large and euchromatin nucleus and B or β cells with small and heterochromatine nucleus. Common HEPATOPANCREAS duct opened in the middle part of intestinal bulb. The results showed that although the HEPATOPANCREAS structure of tenopharyngodon Idell fish has many similarities other fish species HEPATOPANCREAS of Lungfish (Stoskopf 1993) and Fat Head (Takashi, Yonkos and Kane 2001), it has also considerable structural differences.
