摘　　要：通过对多种作物干种子进行等离子体处理发芽试验 ,结果表明 ,等离子体处理后 ,种子的萌发力显著提高 ,种子活力增强 ;同时发现 ,不同作物或同一作物不同品种对等离子体的敏感度和耐受性有所不同。此外 ,等离子体能明显促进种子的抗旱萌发力 ,在水分胁迫条件下 ,小麦种子的发芽势和发芽率分别提高 2 3.3%～ 15 2 .9%和8.3%～ 5 4 .8%。Germination experiments were carried out for several crops in seed treatment by plasma. The results showed that germination percentage and vigor of seeds were increased. It was discovered that different crops or varieties had different sensitivity and endurance to plasma. Plasma could improve germination of seeds in drought. Under the water stress condition, germination power and germination percen tage of wheat seeds were raised by 2.3%~109.3% and 8.3%~54.8% respectively. Crop seeds treatment by plasma could develop to a new technology for the increase of crops yield.\;
