Elms are threatened by Dutch elm disease, and conservation methods needed to protect their genetic diversity. Cryopreservation of dormant buds allows large numbers genotypes be conserved with small space requirements minimal upkeep. through slow controlled cooling was tested for both species native Finland, Ulmus glabra laevis. Regeneration the thawed micropropagation studied on different basal...

Abstract Mulberry ( Morus alba L.) leaf, a “source of both medicine and food”, contains antioxidant ingredients such as flavonoids, alkaloids polyphenols. The effects 6-benzylaminopurine (6-BA) treatment on plant growth flavonoid contents in mulberry leaves were investigated this study. expression rutin (Rut), chlorogenic acid (ChA), isoquercitrin (IQ) astragaloside IV (Ast) related genes the s...

The growth rates of tobacco callus tissues on media containing 10(-6) to 10 mum 6-(gamma,gamma-dimethylallylamino)purine (2iP) were measured. At concentrations of 10(-4) mum and above growth rates were exponential and dependent on cytokinin concentration. At 2iP concentrations of 10(-4) to 0.33 mum, the exponential rate was maintained for 4 to 5 doublings of fresh and dry weight. After this per...
