The influence of temperature on corn seed water uptake

Abstract

Temperature is a very important factor which effects seed water uptake. In this paper we investigated the effect of high temperature and high humidity on seed rate imbibition for five corn hybrids. Seeds were placed at the temperature of 4l°C and 95-100% relative humidity (treatment). These seeds were compared with control. Seeds were hydrated at 12°C and 20°C fur 6, 12, 24, 48 h. The highest imbibition rate was shown by ZP SC 599 hybrid seed. The lowest imbibition rate was shown by ZP SC 599 hybrid seed. The seed treated at 12°C had the lowest imbibition rate. At 20°C differences in imbibition rate were lower than at 12°C.
