摘要: 通过1986~2001年对450余份桃品种需冷量的7.2℃模式、0~7.2℃模式(不包括0℃)和犹它模式比较分析,归纳出桃品种需冷量的评价模式为:以秋季日平均温度稳定低于7.2~C的日期为需冷量测定的起点,以0~7.2℃累积低温值作为需冷量的评价标准比较适宜;犹它模式在中需冷量和长需冷量范围内能有效预测休眠的结束,而不适宜低需冷量品种的测定;7.2℃模式不适宜作为需冷量的评价模式。品种的需冷量与叶芽开放和始花期的相关系数分别为0.52和0.58,均达到极显著水平。提出了桃品种需冷量评价的系列标准参照品种。

Abstract: 7.2℃ 、0—7.2℃ and Utah model were used as estimation of the chilling requirement of mole than 450 peach varieties at Zhengzhou in Henan from 1986 to 2001.The results showed that: The date of average temperature in autumn equal to or lower than 7.2℃ was appropriate for the initial date of efective chilling accunlLi—lation,0—7.2℃ mod el could be suitable for predicating efectively rest completion;Utah model performed aCELI—
mtely in normal and long chilling requ irement; but 7.2℃ mod el Was inefective. The correlation coeficient of chilling requirement with leaf bud breaking an d initial blooming, were 0.52 an d 0.58 respectively, both of them reached significant levels.Reference pe ach cuhivam for chining requ irement determining were given.
