Abstract
Dehydration tolerance of seedlings of ten cultivars and strains of spring wheat (Triticum aestivum L.) was drastically lowered on the 5th day of germination. The “break” in dehydration tolerance is coincident with intensive mobilisation of seed grain reserves and accumulation of dry mass in vegetative organs. Following rehydration, survival of 4-day old seedlings was almost complete, whereas survival of 6-day old seedlings was drastically reduced. The observed phenomenon seems to be genetically determined.
