Abstract: The paper aims to reveal the impact of asymmetric temperature change in the climate warming context on plant phenophase. The authors analyzed the response of specific fruit phenophase to the asymmetric warming in Tarim Basin on the basis of meteorological and phenological observation data during 1980-2014. The results showed that, over the past 35 years, the annual average maximum and minimum temperatures in the region increased with asymmetry in time series, and the change tendency rate of annual average minimum temperature was 2 times warmer than the annual average maximum temperature. The increase of temperature in spring was more obviously than in other seasons. The spring phenophases of several kinds of specific fruits were found commonly earlier while the autumn phenophases were postponed. As the annual average temperature increased 0.1℃, the growing season extended by 1.5 days on average. Thus, most spring phenophases were clearly correlated negatively with the average, the highest and the lowest temperatures of the current month and the previous month (P<0.01), moreover, they also had extremely negative correlations with the monthly average diurnal range of the previous month (P<0.01). The temperature change in spring is the critical factor for the phenophases of specific fruits, and the variation of monthly average minimum temperature affects the phenological periods of fruits more significantly than the monthly average maximum temperature.
