[Effect of increased temperature in boll period on fiber yield and quality of cotton and its physiological mechanism].

To study the effect of temperature increase in boll period (13-Jul. to 24-Aug. ) on cotton yield and fiber quality under the global warming background, a pot experiment with cotton cultivar Simian 3 was carried out in half-open-top greenhouse in Pailou experiment station (32 degrees 02' N, 118 degrees 50' E) of Nanjing Agricultural University in 2010 and 2011.
