摘　　要：为了了解美国黑核桃在西藏适宜的播种时期,引种51个黑核桃品种或品系,在西藏林芝进行了育苗,通过层积催芽以及育苗,培育出了46个品种的实生苗,其中未见萌芽的有：Farrington、Kwik Crop、Pammel Park、Surprise等。同时发现：各品种的层积催芽所需时间因品种、采种母株以及育苗地环境条件不同而不同,在西藏层积催芽至少需要进行90-200 d。In order to screen suitable sowing period of Juglans nigra L. in Tibet, 51 breeds or strains were introduced, and seedlings from 46 breeds or strains were gained by stratification accelerating germination and cultivation, but some don＇t germinate, including Farrington, Kwik Crop, Pammel Park, Surprise, and so on. Otherwise, accelerating germination durations were different between breeds or strains, stock plants and environment, and it was 90-200 days at least in Tibet.
