Primary cassava somatic embryos were induced on a medium without CaCl(2), however, no or only a few secondary somatic embryos were formed from them. With 15 mM CaCl(2) in the medium for induction of cassava primary embryos, more secondary somatic embryos were produced from them, and they were much effective in maintaining their embryogenic capacity than the controls of embryos which were induce...

Bronchogenic cysts are congenital lesions caused by the abnormal budding of the trachea-bronchial tree in the embryogenic period. İntramural esophageal bronchogenic cysts occur by the abnormal budding seen between mucosa and muscle layers of the esophagus which is an extremely rare localization. İntramural esophageal bronchogenic cysts is asymptomatic until it reaches to a large size. A complic...

Heterodera mediterranea completes embryogenic development in 15-18 days at 24 +/- 2 C. On olive and pistachio seedlings the postembryogenic development was completed in 42-50 days at 24-30 C. Juveniles and adults have semiendoparasitic habits and do not penetrate completely into the root tissue. This cyst forming nematode has been detected only on Olea europaea, Pistacia lentiscus, and P. vera....

Somatic embryogenesis was achieved in four leguminous tree species, that is, Acacia catechu, Acacia arabica, Hardwickia binata, and Dalbergia sissoo using immature zygotic embryos as explants on Murashige and Skoog (MS) medium supplemented with 0.25-1.0 mg/l Kn (kinetin) and 2.0-3.0 mg/l 2,4-D (2,4-dichlorophenoxyacetic acid) or NAA (1-napthaleneacetic acid) and 3% sucrose. MS medium containing...

The objectives of this work were to evaluate in vitro response of Iranian alfalfa cultivars and select high regenerative genotypes. Somatic embryogenesis response of leaf and petiole explants from five alfalfa cultivars and landraces was studied using six regeneration protocols. Cultivars and landraces exhibited protocol, and explant-specific response and somatic embryo formation occurred only ...
