Abstract:
Taking 21 Vitis amurensis germplasm resources as materials，in vitro subculture plantlet were conducted，and the effect of damage symptoms，damage index and salt injury index of salt-resistance growth index under 0.2% NaCl in the rooting medium were studied.And the main element analysis of salt injury index of salt-resistance growth index of Vitis amurensiswere made.The results showed that the difference of damage symptoms，damage index and salt injury index and salt-resistance growth index among different germplasm resources was significant.The results of the main element analysis showed that the index of Vitis amurensis germplasm in vitro was rooting rate>root length>damage index>plant height>lateral bud germination rate，and these 5 growth indexes could be used as identification index to evaluate the salt tolerance of Vitis amurensis germplasm resources in vitro.
