Abstract
The ability of the zygotes and seedlings of the green alga Ulva lactuca to develop under the influence of crude oil in various concentrations was determined. The oil at a content of 1 mg/l in water does not have a damaging effect on the germination of zygotes and their further development into multicellular seedlings. Juvenile seedlings have a wider tolerance range than zygotes and can develop under oil content in marine water up to 3 mg/l. The real threat of the death of zygotes, which rovide replenishment of ulva algae thickets in the littoral with young thalli, is observed under short-term oil pollution of more than 25 mg/l, or with constant oil pollution of more than 5 mg/l. The oil content in water of 25 mg/l and above stops the development of most seedlings by irreversibe destroying the structure of their cells.
