6个美国扁桃品种在新疆喀什地区的引种适应性

The Adaptability Study of Introduced Six American Almond Varieties in Xinjiang Kashi

以新疆喀什地区品种纸皮为对照(CK),对连续3a从美国引进的Nonpareil、Sonora、Mission、Thompson、Ne puls ultra和Butte在物候期、坐果率、光合特性、田间适应性、种子及种仁性状和产量方面进行对比试验。结果表明,引进的6个品种均可以适应新疆喀什地区暖温带大陆性干旱气候条件,表现出开花期晚、光合作用强、坐果率高、进入结果期早及丰产性强等特性;另外,从丰产性、果实经济性状及田间适应性方面考虑,Butte和Nonpareil 2个品种可作为新疆喀什地区发展美国优良扁桃品种的主栽品种,其他品种可作为授粉品种适当发展。

In order to provide technical data for introduction and cultivation of American almond in Xinjiang Kashi,six introduced American almond varieties-Nonpareil,Sonora,Mission,Thompson,Ne pulus ltera and Butte were compared with Xinjiang local almond variety Zhipi on phenophase,fruit setting,photosynthetic characteristics,field adaptability,characteristics of almond kernel and yield for three consecutive years.The results showed that the six introduced American almond varieties could bloom and bear fruits normally under the warm and arid continental climate of Xinjiang Kashi and displayed later flowering,stronger photosynthesis,higher fruit setting,earlier fruiting and higher yield.For the consideration of yield,economic traits and filed adaptability,Butte and Nonpareil were chosen to be the two main varieties developing in Xinjiang Kashi,others could be developed to be the pollinator lines.
