High-Frequency in Vitro Direct Shoot Regeneration from Nodal Explants of Hyssop Plant (Hyssopus officinalis L.)
Considering great medicinal value of Hyssopus officinalis L. and possibility of its mass production through in vitro culture, two individual experiments was conducted. Effect of various concentrations (0, 2.2, 4.4 and 11 µmol) of TDZ and BAP in combination with 1 µmol of IAA on direct regeneration from nodal explants were assessed. Significant difference between treatments was observed (P≤ 0.01...
متن کاملImproving adventitious shoot regeneration from cultured leaf explants of Petunia hybrida using thidiazuron
The effect of various concentrations of thidiazuron (TDZ) with or without 2.7 μM of α-naphthalene acetic acid (NAA) on adventitious shoot formation of two Petunia hybrida cultivars was studied. Seeds from ‘Daddy Blue’ and ‘Dreams White’ cultivars were germinated in vitro. Expanded leaves from both seedlings and regenerated shoots were taken as explants. Explants were placed on MS media supplied...

متن کاملHistology of the regeneration of Paulownia tomentosa (Paulowniaceae) by organogenesis.
Paulownia tomentosa is a fast-growing tree species with a considerable economic potential because of its value for wood as well as its high biomass production, and elevated stress tolerance. The objective of the present study was to evaluate the development of adventitious buds in leaves obtained from four-week-old shoots of P. tomentosa, in order to identify the cells involved in in vitro adve...
متن کاملC-geranyl compounds from Paulownia tomentosa fruits.
Five geranylflavonoids, one prenylated flavonoid, and a simple flavanone were isolated from an ethanolic extract of Paulownia tomentosa fruit. Tomentodiplacol (1), 3'-O-methyl-5'-methoxydiplacol (2), 6-isopentenyl-3'-O-methyltaxifolin (3), and dihydrotricin (4) are reported from a natural source for the first time and 3'-O-methyldiplacone (6) for the first time from the genus Paulownia. The str...
