摘　　要：通过对4个不同品种(Mahan、Pawnee、钟山25、金华)薄壳山核桃花期特性的观测,结果如下:(1)4个品种在4月底至5月初相继进入雌花初期,其中Mahan最早进入初花期,最佳可授期持续5～7 d;(2)4个品种雄花散粉时间均较短,仅持续3～5 d,其中Pawnee在5月2日最早开始散粉,其他3个品种均在5月中旬散粉;(3)观测4个品种的雄花散粉期和雌花可授期的相遇情况,得出适宜的授粉组合:分别为Mahan×金华、Mahan×Pawnee、Pawnee×钟山25、Pawnee×Pawnee。By observing the flowering phenology characteristic of 4 varieties of Carya illinoensis （ Mahan, Pawnee, Zhong shan 25 and Jinhua）, We obtained the results as follows, （ 1 ） The early flowering stage of female flower of them were from the end of April to the early of May. Among them, Mahan was the earliest variety, and its best pollination period lasted for 5 7 days. （2） The period of Male flower of 4 varieties were all short,with the duration of 3 to 5 days. Among them ,the pollen of Pawnee dispersed on May 2, earlier than the other 3 varieties whose period was at middle of May. （3） By observ ing the crossing situation of the period of Male flower and female flower, we worked out the appropriate combination of polli nation which was Mahan x Jinhua, Mahan x Pawnee, Pawnee x Zhongshan 25, Pawnee x Pawnee.
