| Abstract: | Embryogenic calli of Lolium perenne L.variety Derby from one seed were carried by Shenzhou No.7 spaceship for space treatment.Plants were regenerated from carried calli(SP) and uncarried calli(NSP).The SPAD value(an index of relative chlorophyl(content)),relative water content(RWC),leaf width,fresh weight per unit leaf area,and dry weight per unit leaf area were measured to compare the differences of growth traits and variation frequency between SP group and NSP group.The results showed that coefficients of... |
