摘要: 研究了沙生芦苇胚性愈伤组织(SREC)和水生芦苇胚性愈伤组织(WREC)在PEG-6000的胁迫及外源ABA的影响下一些生理生化特性的变化.结果显示:从相对生长量和细胞活力上看,SREC的抗渗能力大于WREC;WREC的可溶性蛋白质含量下降幅度大于SREC.外源ABA对WREC的作用大于SREC.SDS-PAGE表明,SREC在30%PEG胁迫下出现了一条17kD的特异蛋白带;在PEG胁迫同时施加外源ABA后,二者均出现此蛋白带.

Abstract: Physiological and biochemical response of the embryogenic calluses of sand reed (SREC)and water reed(WREC)to PEG-6000 osmotic stress and exogenous ABA was studied.The result showed that the ability of osmotic stress resistance of SREC was obviously greater than that of WREC while the decrease of soluble protein in WREC was more than that in SREC.The response of WREC to exogenous ABA(10 μmol/ L)was much more sensitive than that of SREC.SDS-PAGE analysis showed a new 17 kD protein band when SREC was treated with 30 %PEG-6000 osmotic stress or when SREC and WREC was treated with 30% PEG-6000 osmotic stress and exogenous ABA simultaneously.

Key words: Reed ecotypes, Embryogenic calluse, Osmotic stress, ABA, Protein
