Abstract The changes of seed vigor and various physiological indexes of welsh onion during normal and ultra-dry storage were studied.After stored at normal condition for 12 months,the seed vigor of welsh onion decreased with the extending of storage time.The seed vigor,SOD and POD decreased significantly;and electric conductivity,the content of soluble sugar and MDA increased significantly.But after 18 months of ultra-dry storage,the germination rate,germination index,vigor index,electric conductivity,the content of...
