Abstract

SUMMARY Predisposition to hollow heart in pea seeds (Pisum sativum L.) is caused by high ambient temperatures during their maturation on the plant, and by drying them when immature. Symptoms develop during germination, and the proportion of seeds affected in any sample depends on the rate of water imbibition. It is suggested that predisposed cells die during rehydration.
