In Vitro Early Ontogenic Studies of Actiniopteris Radiata (swartz) Link. under Different Medium
نویسندگان
چکیده
Actiniopteris radiata (Swartz) Link. is a fern belonging to the family Pteridaceae. The spores collected from the pinnae of A.radiata was inoculated in Knudson’s C and Knop’s medium at pH 5.8. The ontogenic pattern such as germination type, prothallial development and micromorphological changes were studied in detail. The germination of the spore was Anemia type. The gametophyte development was Ceratopteris type. The growth area in Knudson’s C medium(KC), Knop’s (Kn) medium and brick pieces supplemented with Knudson’s C medium showed different germination percentage, growth area and micromorphology. In micromorphology, the apical notch formation varied in different medium. Few antheridiate prothalli could be seen in Knop’s medium.

Successive extracts of whole plant of Actiniopteris radiata screened for its therapeutic potential as an antiallergic and antistress agent in asthma using specific in vivo animal models. Only ethanol extract (AREE) at a higher dose of 100 mg/kg i.p significantly (p < 0.05) decreased milk induced eosinophilia by 16.20 ± 2.235 when compared with control group while even lower doses of 50 mg/kg, i...
متن کاملP-20: Determination of Effect of Melatonin on In vitro Maturation of Bovine Oocytes under Heat Stress
Background: Melatonin (N-acetyl-5-methoxytryptamine) is a multifunctional molecule that mediates several circadian and seasonal processes in animal reproduction. Melatonin and its metabolites are antioxidants and free radical scavengers. Furthermore, melatonin has been shown to act as an indirect antioxidant, and it is able to increase the activity of glutathione synthesis, and many others dire...
