| Abstract: |
| Based on the agro-meteorological data during 1981～2004,the influence of climate change on apple growth in Tainshui City of Gansu Province were analyzed.The results showed:(1) the warming-dry climate resulted in the advance of apple growth period;(2) after full blossom,the high temperature,drought and interval low temperature made fruit setting ratio decrease;(3) the effect of average temperature on yield was most dominating,and the main meteorological conditions causing the yield reduction were the great fluctuation of temperature in April or May and the drought and low temperature during flower bud emergence phase in April;(4) the average temperature in July was the main influencing factor of apple quality,and the distinct enhancement of temperature in July was the primary climate reason of reduction of apple quality since 1990's. |
