  • Patent number: 4658539
    Abstract: The present invention relates to a process for bringing pregerminated seed n a sowable and for some time storable form. The invention further relates to pilled pregerminated seeds.According to the invention the pregerminated seed is pilled, whereas in the pilling mixture at least one compound which slows down the germinating process is included under formation of a moist pill in which a suitable micro-climate is secured until the time of sowing.This required micro-climate inside the moist pill is obtained by addition of compounds which have a retarding action to the germinating process, such as compounds having an osmotic effect, e.g. water soluble sugars and their derivatives, salts, or glycols and their polymers; or having a growth retarding action, e.g. absicine acid.
