  The effects of NaCl stress at different concentrations on germinating characters of muskmelon seeds were studied in culture dishes.The results showed that higher concentration of NaCl stress slowed water absorption of the germinating seeds,though no effect was observed at early stage of water absorption.Lower concentration of 50 mmol·L -1 promoted the growth of Huanghemi s radicle,with the increasing of NaCl concentrations,germination process was delayed,relative germination index,relative vitality index an...

  The tomato genetic transformation system was established by cocultivated cotyledons of four varieties of tomato with agrobacterium tumefaciens EHA 101 including the plasmid pEbisLycBHyg.Then LycB gene can be transformed into tomato via agrobacterium tumefaciens.Regeneration plants of tomato were obtained by callus inducing,bud inducing,striking root cultivation and hygromycin screening in selective condition.PCR and PCR-Southern analysis of these resistant plants proved that LycB has been transferred into g...
