Salinity Tolerance Identification and Screening of Maize Inbreeds in Seedling Emergence Stage

doi:10.7668/hbnxb.2007.05.006

Abstract

Abstract: Maize inbreeds of 14 varieties were treated with NaCl solutions of different concentration and their salinity tolerance during seedling emergence stage were analyzed. The results were as the follows: maize inbreeds were sensitive to salt stress; different salinity stress had inhibition effects on the germination rate, shoot length, relative water content and net photosynthetic rate; different inbreed had obvious difference in salinity tolerance; the best one was XS98-28; the next was XSK5; the middle were in turn XSF, XS01-61; the lower were other inbreeds.

Key words: Maize, Seedling emergence stage, Salinity tolerance, Identification, Screening
