磁场对杉木陈种子萌发及其萌发过程中内源激素含量的影响

Effects of Magnetic Treatment on the Germination and Interal Hormone Content during the Germination of Chinese Fir Seeds

杉木种子在低温零上条件下贮藏四年以后,种子活力受到明显影响。但是经过3000高斯处理5分钟以后,发芽率基本恢复到原来水平,比对照提高16.87%,发芽势和胚根生长量分别提高17.51%和89.22%。这是因为磁场处理,提高了杉木种子在萌发过程中,尤其是在露白以后,内源激素GA_3、IAA、CTK的含量,并抑制了ABA的活性。

Chinese fir (Cunninghamia lanceolata) seeds had been stored for 4 years at low,temperature above zero degree, It's vigour suffered to obvious impair. But after treating 3000G. S. 5 min., germination percentage had been regained its original level, higher than the controlby 16.87%, germination speed and radile growth higher than the control by 17.51% and 89.22%.Because interal hormone content during the germination, especially after germination, GA_3, IAA,CTK was increased and ABA was decreased by magnetie treatment.
