摘　　要：根据2011—2012年对陕西省杨凌地区18个不同核桃品种的物候观测记录,结合同期气象资料,分析了各核桃品种物候期变化及其对气温的响应情况。结果表明:核桃各种源物候期的差异主要集中在雌花期。核桃5个主要物候期与日均温的相关性显著,且萌芽期、芽开裂期和展叶期之间有相关性,均为极显著正相关。With 18 different walnut cultivars in phonological period in the nursery of Yangling, Shannxi Province, China, the ex-periment was conducted to study the relationship between the phonological period of walnut and the airtemperature in 2011-2012.Different phenological phases of walnut cultivars are infemale phase.Five mainly phonological-phases of walnut have significantly positive correlations with daily temperature , as well as the correlations of germination , bud cracking and leafing stages.
