Abstract
A series of experiments were conducted about the effects of different CO2 concentrations and ventilating time on cotton using OPT-1 open top chambers.The results show that.for all the ventilating treatments,the development stages of cotton were advanced,plant height increased,the biomass of root and stalk increased when CO2 concentration increased:the number of bolls formed in summer was more than 85% of the total for the treatment of 700 ppm CO2 concentration;single boll weight,the number of bolls per plant,ginned and unginned cotton weights,and stalk weight increased obviously when CO2 concentration increased,but the influences of CO2 enrichment on the ratio of ginned weight to the total weight of ginned and unginned cotton,fibre length and ginned weight of 100-seed were small.
