abstract genetic diversity of german chamomile (matricaria chamomilla l.) populations in iran was evaluated using morphological, agronomical and phonological characteristics and compared with three cultivars from germany, hungary and iran. in this experiment, statistical design of rcbd with three replications was used, sixteen quantitative traits were measured such as yield, flower number per p...

abstractbackground and purpose nowadays, the application of antioxidants and plant growth regulators has discussed for decreasing the negative effect of different stresses. ascorbic acid and sodium nitroprusside have substance caused witch the resistance to biotic and abiotic stresses. to evaluate the effect of ascorbic acid and sodium nitroprusside foliar application on some traits of safflowe...

this study was conducted to investigate the hair production and fleece characteristics of hairy goats according to the sex and age of animals. the material of the study consisted one total data of 73 hair goats, which were between more than one year-old and one year-old lori goats from both sexes (26 males and 47 females). the overall fleece weight, fiber length, lock length, washing yield, hai...

in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...

The present study was undertaken to assess the relative efficiency of three different collection techniques of ovarian biometrics and oocytes grading percent of oocytes in local goats of Andhra Pradesh The mean oocyte recovery from right and left ovary was 1.9 ± 0.28 and 0.8 ± 0.18 in aspiration technique, 2.15 ± 0.31 and 2.9 ± 0.46 in dissection technique and 6.55 ± 0.57 and 4.51 ± 0.46 in sli...

The electromagnetic field (EMF) has an effect on various organs, including the female reproductive system. purpose of this study was to evaluate impact carnosine ovarian follicle number and diameter in rats exposed a 900 Megahertz (Mhz) field. In study, six different groups were used. 40 divided into evaluated. ovaries removed at end study. Routine histological procedures performed tissues. Fol...

BACKGROUND The negative impact of rising progesterone levels on pregnancy rates is well known, but data on mature oocyte yield are conflicting. We examined whether delaying the oocyte maturation trigger in IVF/ICSI affected the number of mature oocytes and investigated the potential influence of serum progesterone levels in this process. METHODS Between January 31, 2011, and December 31, 2011...

The specific binding of vitellogenin to chicken oocyte membranes was characterized. This major hen serum phospholipoglycoprotein and one of its lower-molecular-weight components, phosvitin, bound to oocyte membranes with KD values of approx. 6 x 10-7 M. The optimum pH for binding was 6.0, the same as the pH of yolk contents. Phosvitin and vitellogenin compete with each other for binding; other ...

plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. in this study, field experiment carried out as factorial randomized completely block design (rcbd) in 3 replications. different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. second factor was different plant spaces (10, 15, 20 and 25 cm). results showed th...

Diplotene oocyte nucleus of the scorpionfly Panorpa communis is transcriptionally silent and contains numerous nuclear bodies including interchromatin granule clusters (IGCs). The latter consist of the granules of 30-50 nm in diameter and contain IGC marker protein SC35 as well as RNA polymerase II. In this study, we also localized in P. communis oocyte IGCs the transcription coactivators CBP/p...
