| 摘 要： | 为探索谷子地方品种发芽期和苗期的耐盐性,为谷子耐盐机制研究和新品种耐盐培育提供依据,采取NaCl浓度0、50、150、300 mmol·L-1处理沧344、冀谷31、安04-4783、206058、沧555、200131、200152、安06-6082、济0404、济0515、06766-7、郑06-3、长生08、冀谷19共14个夏谷种子,对种子萌发和幼苗生长的变化进行了研究。结果表明：低浓度NaCl处理（50 mmol·L-1）能促进谷子种子萌发,提高种子的相对发芽率,并促进幼苗胚根和胚芽的伸长,增加相对根长和相对芽长;NaCl处理浓度超过150 mmol·L-1时抑制谷子种子萌发和幼苗生长,而且对幼苗胚根的抑制作用大于胚芽,表现为相对根长的降低大于相对芽长的降低。

| Abstract: | In order to explore the germination and salt-resistance of local varieties,provide references for study of salt resistance mechanism and breeding of new salt resistance varieties,Cang344,Jingu31,An 4-4783,206058,Cang555,200131,200152,An06=6082,Ji0404,Ji0515,06766-7,Zheng06-3,Changsheng08 and Jingu 19 were taken as materials,the effect of NaCl（0、50、150、300 mmol·L-1） stress on different varieties seed germination and seedling geowth of Setaria italica（L.） were studied.The results indicated that NaCl concentration of 50 mmol·L-1 treatment could promote germination and seedling growth of differrent seed.When NaCl concentration over 150 mmol·L-1,it restrained the germination and seedling growth,and the restrain on radicel was bigger than that of on plantule,the relative radicel length was longer than relative plantule length. |
