Abstract: With temperature decrease, maximum fibre elongation of cotton decreased and elongation period increased. Night temperature showed larger influence on fibre elongation than daily average temperature. While fibre break strength was increased with cotton boll age, it was reduced when temperature dropped. Fibre maturity was increased as fibre developed and the rate of increase decreased with boll age. Fibre fineness decreased with fibre development. Daily average temperature of 16.7 ℃ and cummulated temperature of 1142.9 ℃(≥15 ℃) are the critical points of fibre fineness. Fineness decrease rate was reduced when temperature was below this temperature. At the same boll age, fineness increased when temperature was decreased.
