The Effect of Coumarin on Uptake of Water by Seeds
Institute of Soil Science and Cultivation Putawy, Poland
There is a marked effect of coumarm on the water uptake of wheat seeds: uptake by the embryo is inhibited, but uptake by the endosperm is unaffected. Even in the early swelling stage, water uptake by embryo and endosperrn thus appears to involve two distinct mechanisms. It is suggested that the inhibitory effect of coumarin on germination is primarily due to its effect on water uptake by the embryo.
