Abstract

Each combination of two of three seed treatments, namely soaking, heating (storage at 30℃) and hulling (removal of bracts), was applied to green panic seed, and seed responses to these combinations were investigated. It was thought that soaking made better germination by leaching water-soluble inhibitors and hulling made better germination by removal of water-soluble and water-insoluble inhibitors in bracts. And so, hulling was a better method than soaking to improve germination. Soaking resulted in worse gerimination with seeds that possibly showed better germination due to heavy rain and a comparatively low temperature during the ripening periods, and the negative effect appeared clearly in the case thta the seed was hulled before soaking. Heating improved germination by different way from soaking or hulling, affecting mainly to a portion of seed except bracts. Combination of heating and hulling improved markedly germination.
