赤霉素对盐胁迫下甘蓝种子萌发及幼苗生长的影响
Effects of Gibberellins on Seed Germination and Seedling Growth of Brassica oleracea L.under Salt Stress
摘要
Abstract
[Objective ] To research the effects of gibberellins on seed germination and seedling growth of Brassica oleracea L.under salt stress.[ Method] With Zhonggan 11 as the test material, we researched the effects of different concentrations of gibberellins on seed germina-tion, seedling growth, leaf POD and SOD activities and MDA content of B.oleracea under salt stress were studied.[ Result] Morphological in-dexes such as germination rate, germination rate, germination index, plant height, and maximum root length and root-shoot ratio were the highest at 100 mg/L gibberellins treatment, which were 79%, 96%, 76.555, 16.900 cm, 13.788 cm and 0.268 respectively.The activities of POD and SOD were the highest in the leaves of the seedlings, which were 122.5 U/g· min and 269.446 U/g.And malondialdehyde con-tent was the lowest, which was 0.289 μmol/g .[Conclusion] 100 mg/L gibberellins treatment could alleviate salt stress effectively and pro-mote seed germination and seedling growth of B.oleracea.关键词
