摘要:

【目的】研究盐/碱胁迫对新型转基因高产棉花萌发期和苗期生长发育的影响并对其耐盐性与耐碱性进行评价。【方法】以转Bn-csRRM2基因高产棉花HN9311和亲本对照中棉所12号(CCRI-12)为研究对象,在盐胁迫(150 mmol/L NaCl)和碱胁迫(70 mmol/L NaHCO3)下,统计和分析生长发育相关指标及差异。【结果】与对照相比,除真叶数和根冠比以外,在盐胁迫和碱胁迫下HN9311萌发期和苗期各项直接指标均显著下降;除萌发期碱胁迫下相对下胚轴长和相对发芽指数以及苗期碱胁迫下相对根冠比以外,HN9311萌发期和苗期各项相对指标均显著低于或等于中棉所12号;HN9311萌发期相对盐/碱害率分别为27.00%、21.00%,中棉所12号分别为22.75%、23.00%,HN9311相对盐害率显著大于中棉所12号。【结论】盐/碱胁迫对HN9311萌发期和苗期生长发育均具有显著的抑制作用,与盐胁迫相比其苗期对碱胁迫更为敏感,萌发期耐盐胁迫能力和苗期耐盐/碱胁迫能力均低于中棉所12号。

Abstract:

【Objective】 This study aims to explore the effects of saline/alkali stress on the growth and development of new transgenic high-yield cotton at germination stage and seedling stage, and evaluate its saline/alkali tolerance. 【Methods】 In this project, transgenic Bn-csRRM2 high-yield cotton HN9311 and CCRI-12 (parent control) were used as study materials, the values and differences of growth and development related indexes were calculated and analyzed under saline stress (150 mmol/L NaCl) and alkali stress (70 mmol/L NaHCO3). 【Results】 Except the number of true leaves and root/shoot, the other direct indexes of HN9311 at germination stage and seedling stage significantly decreased under saline stress and alkali stress when compared with those of CCRI-12; Except for relative hypocotyl length and relative germination index under alkali stress at germination stage, and relative root/shoot under alkali stress at seedling stage, the other relative indexes of HN9311 at germination and seedling stages were significantly lower than or equal to those of CCRI-12; The relative saline/alkali damage rates of HN9311 at germination stage were 27.00% and 21.00%, and those of CCRI-12 were 22.75% and 23.00%. The relative saline damage rate of HN9311was significantly higher than that of CCRI-12. 【Conclusion】 Saline/alkali stress has a significant inhibitory effect on the growth and development of HN9311 at germination stage and seedling stage. HN9311 is more sensitive to alkali stress at seedling stage when compared with saline stress, saline tolerance at germination stage and saline/alkali tolerance at seedling stage were lower than those of CCRI-12.

Key words: HN9311; germination stage; seedling stage; growth and development; saline/alkali tolerance evaluation
