Abstract
Using the indica rice varieties including Xiangzaoxian 32,Jiazao 935 and Han 116 with different drought resistance as the materials,the effects of exogenous polyamine(PA)regulators on the growth and polyamine content of coleoptiles and young roots under osmotic stress were studied.The results showed that the growth of both coleoptiles and young roots was inhibited under osmotic stress,and the contents of Put,Spd and Spm in coleoptiles and young roots of all rice varieties significantly increased,but the drought-resistant varieties Jiazao 935 and Han 116 had a larger increment than the drought-sensitive variety Xiangzaoxian 32.The exogenous MGBG and D-Arg treatments significantly inhibited an increase in Put,Spd and Spm contents in coleoptiles and young roots,aggravated harm of osmotic stress on them.The exogenous Spd treatment significantly raised Put,Spd and Spm contents in both coleoptiles and young roots,and it alleviated inhibition of osmotic stress on the growth of coleoptiles but aggravated harmful degree of osmotic stress on the growth of young roots.
