Abstract:
Taking the seeds of ‘Datong’ Allium fistulosum that were harvested after anthesis 45,50,55,60,65 days as the test materials,the morphological characteristics and inclusions at different harvest time were dertermined,and germination vigor under different hierarchical dry moisture contents were detected and stored at ambient temperature for 1.5 years.The results showed that the seed plumpness increased alone with harvesting.The moisture content and soluble sugar content were downward trend,and the crude fat and the soluble protein content were upward trend with the increase of harvest time.There was different seed vigor between different maturities seeds in the ultra drying condition.The seed vigor of 2.5 to 3.5 percent water contents were higher than any others.The seed that picked after anthesis 45 days was stored in ultra drying condition,which seed vigor could be increased substantially.The seed that picked after anthesis 60 days was more suitable storage in ultra drying condition.
