为探明影响野生杏花期冻害率、败育率和座果率高低的因素,对伊犁不同地区(四个县)及不同类型的野生杏调查研究结果显示:(1)冻害率在4个不同纬度地区间有显著差异。位于较低纬度的新源县冻害率最高(达57%),位于较高纬度的巩留县冻害率最低(仅4.4%),败育率则是巩留县最高,与其他地区间差异极显著;(2)海拔高度为1300 m时的冻害率为21.4%,而其他高于或低于海拔1300 m的地区则都显著高于1300m处的冻害率,败育率在较低海拔(900 m)地区显著低于其他各海拔高度地区;(3)野生甜仁杏的冻害率显著低于野生苦仁杏,且其败育率也低于野生苦仁杏。座果率则是野生甜仁杏显著高于野生苦仁杏。综合分析得出野生杏花期受冻程度与纬度、海拔高度和杏树的类型有关,败育率和座果率则与纬度和海拔没有必然的相关性,而与其类型有关。野生甜仁杏的抗冻性较野生苦仁杏强。
In order to find out the factors influencing frostbite rate, abortion rate and fruit setting rate of wild apricot, the investigation results of different types of wild apricot in different regions (four counties) of Ili showed that: (1) There are significant differences between latitude and longitude. Xinyuan County at the lower latitude had the highest rate of frostbite damage (up to 57%), Gongliu County at the highest latitude had the lowest rate of frostbite (only 4.4%), and the abortion rate was the highest in Gongliu County (2) The rate of frostbite was 21.4% at altitude of 1300 m, while the others at or above 1300 m above sea level were significantly higher than those at 1300 m m) were significantly lower than those in other altitudes. (3) The freezing damage rate of wild sweet apricot was significantly lower than that of wild kufu apricot, and its abortion rate was also lower than that of wild kimchi. Fruit set rate is significantly higher than the wild sweet kiwi wild bitter apricot. The results showed that the freezing degree of wild apricot was related to the latitude, altitude and the type of apricot. The abortion rate and fruit setting rate were not related to the latitude and altitude but related to its type. Wild sweet apricot frost resistance than wild bitter apricot.
