BACKGROUND
The raising trend of cultivation of ()-transgenic cotton is faced with a new challenge what effects on the growth and yield of cotton under elevated CO.
METHODS
Rhizobacteria is the significant biological regulator to increase environmental suitability and ameliorate soil-nitrogen utilization efficiency of crops, especially cotton. Pot-culture experiments investigated the effects on the yield and fiber quality components of cotton (transgenic Line SCRC 37) inoculated with (AC) under elevated CO.
RESULTS
The findings indicated that the inoculation of azotobacter significantly improved the yield and fiber quality components of cotton, the elevated CO significantly increased the soil density of and the partial yield indexes (as cottonweightper 20 bolls, lint yield per 20 bolls and boll number per plant), and non-significant decrease the fiber quality components of cotton except uniform.
DISCUSSION
Overall results obviously depicted that the inoculation of azotobacter and the elevated CO had positive effects on the yield and fiber quality components of cotton. Presumably, azotobacter inoculation can be used to stimulate plant soil-nitrogen uptake and promote plant growth for cotton under elevated CO in the future.
背景
种植（）-转基因棉花的上升趋势面临着一个新的挑战，即在升高的 CO 下，这对棉花的生长和产量有什么影响。
方法
根瘤菌是增加作物环境适宜性和改善土壤氮利用效率的重要生物调节剂，特别是棉花。盆栽实验研究了在升高的 CO 下接种（AC）对转基因棉（SCRC 37 品系）产量和纤维品质成分的影响。
结果
结果表明，接种固氮菌显著提高了棉花的产量和纤维品质成分，升高的 CO 显著增加了土壤密度和部分产量指标（如每 20 个棉铃的棉花重量、每 20 个棉铃的皮棉产量和每株棉铃数），但除均匀度外，对棉花纤维品质成分没有显著降低。
讨论
总体结果明显表明，接种固氮菌和升高的 CO 对棉花的产量和纤维品质成分有积极影响。推测，固氮菌接种可以用于刺激植物土壤氮吸收，并在未来升高的 CO 下促进棉花的生长。
