Response of seed cotton yields to t

Response of seed cotton yields to temperature changesduring the growth periodsTable 4 shows that the relationships between increasing every1 °C during the three growth periods and seed cotton yieldswere statistically significant. The highest negative correlationcoefficient was produced by the rising maximum temperatureduring the period from seeding emergence to three-leaf andseed cotton yields, and the minimum temperature caused themost loss of seed cotton yields for every 1 °C rise during thegrowth period from seeding emergence to three-leaf. Itshowed that rising temperatures could reduce seed cottonyields in this growth period; however, increasing temperaturesincreased seed cotton yields during the other two growthperiods, and increasing every 1 °C in mean temperature enhanced by 338.75 kg/ha during the period from full bloom tocleft boll.
