“…The dicots are paraphyletic (that is they contain some, but not all, descendants of the most recent common ancestor of that group), whereas the monocots can be defined by several synapomorphies (Anonymous 2005). But kinked twins were firstly observed in soybean as whewellites in Leguminosae (Ilarslan et al 1997). Kinked twins were distinctive characteristics of C. orientalis var.…”

In this study, Ca oxalate crystals were isolated from the leaves and X-ray diffraction identified them as weddelite in Crataegus pontica C. Koch, C. stevenii Polar., C. monogyna ssp. monogyna Jacq. in C. orientalis var. orientalis Pallas ex Bieb. both whewellite and weddelite crystals were found. Although there were some differences among the soluble and insoluble oxalate contents, they were not notable in the species of C. stevenii (10%; 18%), C. orientalis (12.4%; 15%), C. monogyna (12.9%; 13%), whereas in C. pontica the difference was so great with the lowest soluble (4%), and highest (28%) insoluble oxalate content. Crystals have tetragonal or prismatic shape in general but tetrahedral kinked and straight shapes were seen in C. orientalis, tetragonal aggregates in C. stevenii, and also pseudo-tetrahedral cordate (heart) shape were found in C. monogyna ssp. monogyna and C. pontica. As the crystal biomineralization is under genetic control, this characteristic hydration state of crystals of Crataegus orientalis var. orientalis must be important for systematic phylogenetics.

“…Nitrate was extracted from fresh samples by boiling water bath and contents were assayed according to the method of salicylic acid-sulphuric acid with KNO 3 as a standard [27]. The oxalic acid was extracted also from fresh samples by water, clarified with 0.5mol/L HCl in 75°C water bath for 30 min, and contents were determined using the method of sulfonic acid as described by Ilarslan et al with oxalic acid as a standard [28].…”

Portulaca granulatostellulata and P. edulisare two subspecies ofcommon purslane. The biomass of both plants was similar; however, with long upright stems and a long vegetative period, P. edulis production was easier. Both subspecies were rich in vitamin C and flavonoids, main organic nutrients' contents in 25-d-old plants were higher than those in15-d-old plants, and were higher in P. granulatostellulata. Both purslanes were rich in minerals, with the K content being the highest, and was higher in P. edulis, whereas the Ca content was higher in P. granulatostellulata. A similarly high content of polyunsaturated fatty acid, particularly α-linolenic acid, in both purslanes showed their high value in balancing the ω-6/ω-3 intake ratio. Furthermore, all the contents of nitrate and heavy metals in this study were within the safe range, and the oxalic acid content in mature plants decreased to the high level of oxalic acid in vegetables. In brief, both purslanes are excellent reserve crops for use as vegetables and medicines. P. edulis has advantages over P. granulatostellulata regarding plant appearance and the K content. P. granulatostellulata has advantages regarding Vc, flavonoid and other mineral contents; Both purslanes are similar in fatty acid composition and are suitable for picking at a mature stage.

-(Ontogeny and structure of the pericarp and the seed coat of Miconia albicans (Sw.) Triana (Melastomataceae) from "cerrado", Brazil). Miconia albicans fruit and seed coat ontogeny were described under light microscope. The samples were fixed in formalin-aceto-alcohol (FAA), neutral-buffered formaldehyde solution (NBF) and formalin-ferrous sulphate (FFS) solutions, embedded in plastic resin, sectioned at 10 µm and stained with Toluidine Blue. Specific dyes and/or reagents were used for the microchemical tests. The ovary is semi-inferior and the indehiscent, fleshy globose berries are originated mainly from the development of the inferior portion of the ovary. The immature pericarp is mainly parenchymatous with some sclereids, druse crystal and phenolic-like compounds idioblasts widespread in the mesocarp. In the mature pericarp, the endocarp cells are often collapsed, the mesocarp is thick with cells more or less turgid, and the sclereids, the druses and the phenolic-like compound idioblasts are almost absent. The ovules are anatropous, bitegmic and crassinucellate, and the zig-zag micropyle is formed by both the exostome and the endostome. The mature seed is pyramidal-elongated in shape, exalbuminous and testal. The raphal part occupies about 40% of the seed coat total length and had the mechanical layer derived from its inner layer. The antiraphal side is non-multiplicative and the exotesta, mesotesta and endotesta are differentiated into a sclerotic layer, with the exotesta being the mechanical one. The tegmen is absent.Key words -anatomy, fruits, Melastomataceae, Miconia, ontogeny RESUMO -(Ontogenia e estrutura do pericarpo e do envoltório da semente de Miconia albicans (Sw.) Triana (Melastomataceae) do cerrado, Brasil). A ontogenia dos frutos e das sementes de M. albicans foi descrita sob microscopia de luz. Os materiais foram fixados em soluções de formalina -ácido acético -álcool etílico 50% (FAA), formalina neutra tamponada (FNT) e sulfato ferroso em formalina (SFF), embebidos em resina plástica, seccionados a 10 µm de espessura e corados com Azul de Toluidina. Corantes e/ou reagentes específicos foram usados para os testes microquímicos. O ovário é semi-ínfero, e os frutos são bagas indeiscentes, originadas em sua maior parte a partir do desenvolvimento da porção ínfera do ovário. O pericarpo imaturo é principalmente parenquimático, com esclereídes, idioblastos cristalíferos e com compostos fenólicos no mesocarpo. No pericarpo maduro as células do endocarpo estão freqüentemente colapsadas, o mesocarpo é espesso, com células túrgidas, e as esclereídes e os idioblastos cristalíferos e com compostos fenólicos estão em pequena quantidade. Os óvulos são anátropos, bitegumentados e crassinucelados, e a micrópica, em zig-zag, é formada pelo exóstoma e pelo endóstoma. A semente madura é piramidal-alongada, exalbuminosa e testal. A porção rafeal ocupa aproximadamente 40% do comprimento total da semente e possui a camada mecânica derivada de suas camadas internas. A porção anti-rafeal é não-multiplicativ...
