چکیده
th (Hafmer, 1998) and was introduced in India in 16 century from Malacca (Kumar and Abraham, 1983). Papaya is one of the most important fruit crops of Hawaii, Malaysia, Burma, Sri Lanka, India, Queens Land, South Africa, and other tropical and sub-tropical countries of the world. Papaya occupies 2.0 per cent total fruit crop area and 5.3 per cent of total fruit production in India (5381.73 thousand MT of production from 132.18 thousand hectares with

Somatic embryogenesis and plant regeneration from immature embryo explant of papaya (Carica papaya L. cv. washington and honey dew).
Immature zygotic embryo explants of Carica papaya were cultured on MS medium supplemented with 2,4-D (2.0 mg/l) and formed globular embryos on explants without callus formation in 4-6 weeks. Maturation and conversion of somatic embryos was also achieved on the same medium. Cotyledonary stage embryos germinated to 63.66 and 68.33% in cv. honey dew and washington respectively in MS basal medium s...
متن کاملBiomechanical, biochemical, and morphological mechanisms of heat shock-mediated germination in Carica papaya seed
Carica papaya (papaya) seed germinate readily fresh from the fruit, but desiccation induces a dormant state. Dormancy can be released by exposure of the hydrated seed to a pulse of elevated temperature, typical of that encountered in its tropical habitat. Carica papaya is one of only a few species known to germinate in response to heat shock (HS) and we know little of the mechanisms that contro...
متن کاملPlant Regeneration and Somatic Embryogenesis from Immature Embryos Derived through Interspecific Hybridization among Different Carica Species
Plant regeneration and somatic embryogenesis through interspecific hybridization among different Carica species were studied for the development of a papaya ringspot virus-resistant variety. The maximum fruit sets were recorded from the cross of the native variety C. papaya cv. Shahi with the wild species C. cauliflora. The highest hybrid embryos were recorded at 90 days after pollination and t...
متن کاملInhibition of Velvetleaf (Abutilon theophrasti) Germination and Growth by Benzyl Isothiocyanate, a Natural Toxicant!
/ Abstract. Benzyl isothiocyanate (BITC) was extracted from mature papaya (Carica papaya L.) seeds and applied to imbibed velvetleaf (Abutilon theophrasti Medic. #3 ABUTH) seeds. Complete inhibition of germination occurred at a concentration of 6 x l(f4 M BITC, and only 28% (compared to controls) of the seeds germinated after 4 days exposure to the 4 x l(f4 M treatment. Corn (Zea mays L. 'DeKal...
متن کاملDevelopment of Transgenic Papaya through Agrobacterium-Mediated Transformation
Transgenic papaya plants were regenerated from hypocotyls and immature zygotic embryo after cocultivation with Agrobacterium tumefaciens LBA-4404 carrying a binary plasmid vector system containing neomycin phosphotransferase (nptII) gene as the selectable marker and β-glucuronidase (GUS) as the reporter gene. The explants were co-cultivated with Agrobacterium tumefaciens on regeneration medium ...
