Effects of different salt concentration on germination of some triticale lines

Abstract

This study was conducted to determine the responses of some triticale varieties and lines to salt stress at germination stage. Triticale varieties and lines Nortingen, Eronga, Karma-2000, C9, N X 2003-3, NX2002-2, N X 2003-12, N X E-3, 2003 X 2002-10 and 2003 X 2002-8 were used as plant materials. Five different salt stress levels (0, 50, 100, 150 and 200 mM) were applied in this study. The parameter examined were water intake rate of seeds at 12 and 24 h., germination percentage, plumule length, radicle length, plumule and radicle dry weights. The results obtained indicated that salt treatments affected negatively all of the parameters examined. The responses of variety/lines to salt stress were different in respect of all parameters. Variety/lines x salt interactions were significant only for germination percentage and plumule length. N X E-3 and N X 2003-12 lines responded to bemore resistant to salt stress than the other genotypes examined at germination stage.
