水杨酸浸种对高羊茅在干旱胁迫下萌发的影响
Effects of soaking seeds with salicylic acid on tall rescue seed germination under drought stress
摘要
Abstract
Tall fescue （Fescue arundinacea） is a cold-season type turfgrass and is widely used in urban greening. This study was to evaluate effects of socking seeds with different concentrations of salicylic acid （SA） on seed germination of Bonsai 2000, Houndog 5 and Ruby tall fescue under drought stress, which was simulated by PEG-2000. The results obtained from the study indicated that SA at the lower concentration （0.12-1.00 mmol/L） increased germination potential, germination rate of tall rescue seeds promoted growth of seedlings and roots; and improved the drought resistance of tall rescue during seed germination period. However, the higher concentrations （2.00-3.00 retool/L） inhibited seed germination and growth of the seedlings. The treatment with 3.00 mmol/L SA displayed a significant inhibiting effect （P〈 0.05） on tall fescue seed germination. The treatment with 0.5 mmol/L SA showed the best performance in this study.关键词
