Effect of genotype on androgenesis in barley (Hordeum vulgare L.)
Current study was set up to determine the response of 12 Iranian winter diploid barley (Hordeum vulgare L.) cultivars to anther culture on solid FHG induction medium supplemented with 90 mg/l sucrose, 2 mg/l 2,4-D and 0.1 mg/l kinetin. For cold pretreatment each selected spike was kept in a refrigerator at 4 C for 14 days. The experimental design consisted of a completely randomized design (CRD...
متن کاملInfluence of anther pretreatment on the efficiency of androgenesis in barley.
The change in the developmental pathway of microspores from gametophytic to sporophytic is induced by stress during pretreatment of spikes and anthers. In our experiments, anther culture of three barley cultivars was tested with regard to the effect of chilling at 4 degrees C for 28 days, starvation in 0.3 M mannitol solution for 4 days, and a combination of both methods. Chilling was shown to ...

As such they present the physician with the same basic problems-cosmetically disfiguring lesions and extreme sensitivity to sunlight of the involved areas. None of the diseases is itself an immediate threat to life, but the social disabilities, especially among dar...
متن کاملMonosex Tilapia Production through Androgenesis
Control of reproduction is vital to aquaculture and includes artificial propagation as well as management of unwanted recruitment. Developments in manipulation of the reproductive system provide options to enhance production. Nile tilapia, Oreochromis niloticus, spawning was managed by photoperiod and temperature manipulation. A controlled light cycle of 20L:4D and water temperature of 26 ± 2°C...
متن کاملOculocutaneous albinism
Oculocutaneous albinism (OCA) is a group of inherited disorders of melanin biosynthesis characterized by a generalized reduction in pigmentation of hair, skin and eyes. The prevalence of all forms of albinism varies considerably worldwide and has been estimated at approximately 1/17,000, suggesting that about 1 in 70 people carry a gene for OCA. The clinical spectrum of OCA ranges, with OCA1A b...
