[en] Development of bio fertilizer seed treatments for okra seeds were carried out by mixing phosphate solubilising bacteria (AP 3) and plant growth promoter (AP 2) with adhesives. The seeds were coated with inoculum and four types of adhesives namely, Gum Arabic; Polyethylene Glycol (PEG); Sodium Alginate and Methylcellulose respectively. From eight seed treatments, all seed treatments significantly increased seed germinations except treatment T4 (Gum Arabic and AP3). In general, maximum germination rates and log of viable cells were observed when treated with polyethylene glycol 4000 (PEG) mixed with AP2 (T7) and AP3 (T8). These results show that using PEG as adhesive enhanced the germination rates and log of viable cells of AP2 and AP3. Thus, PEG could be a good adhesive for seed treatment. In greenhouse experiment, okra seeds treatment with AP2 and PEG (T1) showed the highest dry weight compared to other treatments. Seeds treatment with AP3 and PEG (T2) showed higher contribution of N compare to seeds treatment (T1). There were no significant different within seed treatments and urea treatment in okra yield. All treatments significantly increased yields compared with control. (author)
[en] The seed oil of 138 accessions of 14 Acer truncatum (Aceraceae family) populations native to China were analyzed by pulsed nuclear magnetic resonance spectroscopy and gas chromatography-flame ionization detection. The oil content ranged from 17.81% to 36.56% (mean: 28.57%), which mainly consisted of 14 types of fatty acids. Palmitic (4.69%), stearic (2.30%), oleic (25.19%), linoleic (32.97%), linolenic (2.76%), cis-11-eicosenoic (7.90%), erucic (16.49%), and nervonic (5.76%) fatty acids accounted for 98% of total fat. The nervonic acid content ranged from 3.90% to 7.85% among the accessions. Significant variations in oil content and predominating fatty acids were observed among populations. Hierarchical cluster analysis and principal component analysis detected obvious geographical variation trends among A. truncatum populations which correlate with environmental variations (especially altitude, temperature, and precipitation) and supported the grouping of the populations into three groups according to geographic locations.
[es]El aceite de semillas de 138 accesiones de 14 poblaciones de Acer truncatum (familia Aceraceae) nativas de China se analizaron mediante espectroscopía de resonancia magnética nuclear pulsada y cromatografía de gases y detección de ionización de llama. El contenido de aceite varió de 17.81% a 36.56% (promedio: 28.57%), y están formadas principalmente por 14 tipos de ácidos grasos. Palmítico (4.69%), esteárico (2.30%), oleico (25.19%), linoleico (32.97%), linolénico (2.76%), cis-11-eicosenoico (7.90%), erúcico (16.49%) y nervónico (5.76 %) los ácidos grasos representaron el 98% de la grasa total. El contenido de ácido nervónico varió de 3,90% a 7,85% entre las accesiones. Se observaron variaciones significativas en el contenido de aceite y en los ácidos grasos predominantes entre las poblaciones. El análisis jerárquico de conglomerados y el análisis de componentes principales detectaron evidentes variaciones geográficas entre las poblaciones de A. truncatum que se correlacionaban con las variaciones ambientales (especialmente altitud, temperatura y precipitación) y permitieron agrupar las poblaciones en tres grupos según las ubicaciones geográficas.
[en] To assess the effect of aqueous extract of Carum carvi seeds in experimentally induced diabetic nephropathy (DN) in rodents, we studied 48 adult male Wistar rats divided into 4 groups: normal controls (group A), diabetes positive control (group B), and experimental (groups C and D). They received Carum carvi extract as a renoprotective agent. Rats having fasting blood glucose levels over 280 mg/dL were included in this study. Group C rats received STZ (60 mg/kg) and aqueous extract of Carum carvi at 30 mg/kg of body weights. On the other hand group D rats received STZ (60 mg/kg) and aqueous extract of Carum carvi at 60 mg/kg of body weight. Blood samples were collected on the 60 th day, and kidneys were also extracted for examination. The diabetic group rats showed a variable increase in the serum levels of glucose, urea, creatinine, total urinary protein and microalbuminuric levels. Body weight decreased and urine volume increased in the diabetic groups. 30 mg/kg body weight of Carum carvi dose decreased the levels of these parameters in rats. On the other hand, 60 mg/kg body weight of Carum carvi dose significantly decreased the levels of the biochemical parameters. The morphological examination of group C rats showed no changes whereas the rats in group D showed moderate changes. Carum carvi constituents, especially flavonoids and carvone have strong anti-oxidant activity, which provides reno-protection against diabetes and its complications. In conclusion, high dose of Carum carvi aqueous seeds extract (60 mg/kg) showed reno-protection against STZ induced diabetic nephropathy in rats (Author).
[en] Pollens and seeds of Hypoestes and Rhinacanthus collected from different field localities in Taiz and Soqotra Island, Yemen were investigated by using light and scanning electron microscopes. Pollen grains of Hypoestes were prolate in equatorial view, lobate trigonal to lobate circular in polar view whereas those of Rhinacanthus were sub spheroidal and rounded trigonal in polar view. The aperture was tricolporate and exine ornamentation was coarsely reticulate for all species in the two genera. Scanning electron microscopy and morphological observations showed that mature dry seeds of Hypoestes and Rhinacanthus have various sizes and shapes, the surface ornamentations observed were reticulate to cristate, an addition to the tuberculum and papillae. The three Hypoestes species differ in the seed structure which are useful for identification and their high structural diversity provides an important taxonomic value for species differentiation.

[en] The objective of this research was to microencapsulating the pumpkin seed oil (PSO) by the spray dryer and also investigating the effects of some process conditions on physicochemical properties of PSO microparticles. Inlet drying air temperature (140-180 C), aspirator rate (55-75%), and peristaltic pump rate (5-15%) effects were studied. Moisture content (%W.b.), Microencapsulation Efficiency (MEE, %) and Peroxide value (POV, meq/kg sample) considered as model responses. Consequently, the ideal drying state for microencapsulation of PSO as a result of optimizing by Response Surface Methodology (RSM) determined with the aim of minimizing the Moisture content and POV and maximizing the MEE.

[en] Study was made on samples of seed culture and fermented wort from Gyogon alcohol distillery. In all samples bacteria contaminants were observed. Samples were cultured on Sabouraud dextrose agar, Czapek Dox agar, and nutrient agar media and broth. The selected colonies were isolated. Biochemical tests for identification were conducted. The yeast and bacteria contaminants were identified by morphological characteristics and biochemical reactions. The yeast isolated and identified from Gyogon alcohol distillery was Sacchacromyces cerevisiae. The bacteria contaminants isolated and identified were Aeromonas sp. and Pseudomonas sp.
