Germination ofSpirodela polyrhizaturions: the role of culture conditions during turion development

摘要

The rapidly germinating“old”turions ofSpirodela polyrhizawere shown to derive mainly from the slowly germinating“young”turions. This modification to“old”turions could occur even in isolated“young”turions, and was accelerated by sucrose. It is suggested that this modification is a form of turion senescence and that turion initiation and maturation are strongly influenced by exogenous carbon and n
