Effects of Temperature and Light on Fiber Quality in Upland High Quality Cotton Abstract：To investigate the effects of temperature and light on fiber quality in Kemian 1, experiments were carried at four different ecological sites in Jiangsu Province. The results indicated that temperature and light at four sites varied significantly. Further regressive analyses indicated that there were different dominant factors affecting different fiber indexes in four types of bolls. The dominant factor affecting fiber length is daily temperature difference. Fiber strength of pre-summer bolls and early autumn bolls was dominantly affected by maximum temperature, while the fiber strength of summer bolls was mainly influenced by daily sunshine duration and daily temperature difference. As for the fiber strength of late autumn bolls, it was mainly influenced by maximum temperature and daily temperature difference. The micronaire readings of fiber in pre-summer bolls were mainly affected by minimum temperature and daily average temperature. The micronaire readings of fiber in summer bolls and early autumn bolls were primarily affected by daily sunshine duration. The micronaire readings of fiber in late autumn bolls were mainly affected by daily temperature difference.
