Correlation coefficient of environmental factors during cotton fiber development period with maximum/minimum sucrose content and sucrose transformation rate in cotton fibers on FP1 and FP3 of two cultivars during 2010–2011.

aSUCmax, maximum sucrose content.bSUCmin, minimum sucrose content.cTr, sucrose transformation rate.dn = 8, R0.05 = 0.707, R0.01 = 0.834. *, significant differences at P = 0.05 probability level.
