Responses of 14 Triticale Germplasms to Saline-alkali Stress at Germination Stage
In order to investigate the effects of salt and alkali stress on seed germination of triticale,four kinds of salt(NaHCO3,NaCl,Na2SO4,Na2CO3)were used to prepare 4 concentrations of salt and alkali solution,and the effects of salt and alkali stress on the germination stage of 14 triticale germplasms were measured.The results showed that the germination indexes of triticale decreased with the increase of salt and alkali concentration.The salt-alkali tolerance of Gannong No.4 was the best,followed by Gannong No.2,and the salt-alkali tolerance of Zhongsi1048 was the weakest.The clustering analysis showed that Qingzhimai5,Gannong No.2 and Gannong No.4 were strong saline-al-kali tolerant groups.Leishen,Youneng,1771,Qingsimail,Qingsimai2,Qingsimai4 and C23 were saline-tolerant intermediate groups.Zangsil,C24,C25 and Zhongsi1048 were saline-alkali sensitive groups.
