We investigated cone traits of Abies fargesii including length, width, fresh weight, seed numbers per cone, and seed traits including length, width, thickness, seed mass and seed germination capacity. The results showed that the average length and width of the cone were 5.37 ± 0.75 cm and 3.01 ± 0.32 cm, respectively, and its fresh weight was 18.93 ± 6.06 g, the seed number per cone was 59–567. The length, width and thickness of seeds were 1.08–8.68 mm, 1.16–6.42 mm and 0.66–3.48 mm, respectively, and the thou-sand-seed mass was 7.30 g. One-way ANOVA revealed that fruiting characteristics were significantly differ-ent both within and between populations. The distribution pattern of frequency of seed numbers per cone dif-fered in different populations. The seed germination rate, seed germination energy and seed germination speed were different among mother trees. The proportion of empty seeds was high, accounting for 75.79% of the total amount due to seed abortion.
