Abstract
A method for selecting live seeds of sugar beet (those which are able to germinate) from dead seeds (those which are unable to germinate) based on the case of seed-cap releasing. When immersed in water, live seeds absorb much water and expand appreciably, while dead seeds expand only slightly because less water is absorbed. This expansion of live seeds upon absorption of water makes the seed caps, closely fitted onto the outer shells of fruit, ready to be released. When mechanical vibrations are given to a mixture of water-soaked fruit, only the seed caps of expanded fruit are easily released. Thus live seeds of sugar beet can be effectively obtained by selecting out the fruit from which seed caps have been released.
