Abstract
Water uptake (after 4 h imbibition) as a function of the moment of its onset shows rhythms with a period length of approx. 6 h. The period length is not affected by a increase in temperature of 10 °C, suggesting that the oscillation is endogenous in character. Furthermore, heat-killed seeds show no oscillations in water uptake, indicating that the rhythm described originates from the temperature-sensitive component of imbibition.
