A PIXE study of vitrification of carnation in vitro culture
نویسندگان
چکیده
PIXE (Proton Induced X-ray Emission) is a well-known method for elemental analyses of specimens in applied studies. In this paper, we report results of an application of PIXE in trace-element analysis of normal and vitrified carnations in vitro culture. Experiments were performed to study the vitrification in connection with the trace elements in carnation tissues. About two hundred PIXE spectra were obtained from seventy samples with an irradiation of 3 MeV protons from the NEC 9SDH-2 Pelletron tandem accelerator. From the PIXE analysis we determined the trace element composition of normal and vitrified carnations. Our results indicate that there is a significant change of K, Ca, Fe and Zn contents in the vitrification process.

In Vitro Culture of Carnation (Dianthus caryophyllus L.) Focusing on the Problem of Vitrification
This study was conducted to evaluate the effect of plant growth regulators on in vitro shoot multiplication, vitrification and rooting of two carnation cultivars (Eskimo Mogr and Innove Orange Bogr). Isolated axillary buds were cultured on MS medium supplemented with different levels of Benzyl amino purine (BAP) or kinetin (Kin) in combination with 0.2 mg/l NAA and shoot multiplication and vitr...

The aim of this study was to evaluate the effects of ovarian tissue vitrification and two-step in vitro culture on the metaphase II (MII) oocyte reactive oxygen species (ROS) level, mitochondrial transcription factor A (TFAM) expression and succinate dehydrogenase (SDH) activity. After collection of neonatal mouse ovaries, 45 ovaries were vitrified and the others (n = 45) were...

Background: Although testicular tissue cryopreservation could be advantageous for fertility preservation in cancerous children, the possibility of apoptosis incidence should not be ignored. Our aim was evaluation of the apoptosis incidence in mouse testicular tissue after vitrification and short-term culture. Materials and Methods: Testes of 7days old NMRI male mice were isolated, divided and d...

Background: Evaluation of maturation genes expression and their pattern during in vitro culture of vitrified preantral follicles is an essential and could promote either vitrification procedure or culture condition. Materials and Methods: Preantral follicles (with 100- 130 μm diameter) isolated mechanically from 12-14 days old NMRI mice ovaries and divided into vitrification and control groups....

Background: Cryopreservation of oocytes is an effective technology in assisted reproductive technology. Although successful vitrification of gametes has been reported in several mammalian species, the survival is generally low. The aim of this study was to investigate the effects of fibroblast growth factor (FGF) and hepatocyte growth factor (HGF) on preantral follicle development after vitrifi...
