Abstract

observed the cone-bearing number, cone biological traits of different clones and ef fect of environmental factors on seed-extracting percentage and full seed percentage. High seed-extracting percentage was not relation to cone type and size, but interrelated to fertile seed scale, seed numbers and thousand seed weight. Well sun light and full pollination could lift seed-extracting percentage and full seed percentage, reduce empty seed and woody seed. Harvest cone in the middle of Novermber had more seed-extracting percentage and thousand seed weight than one in the middle end of October, but had not noticeable difference in germination percentage. Hengfan seed orchard of 1. 5 off spring Chinese fir, 10 yeas old with intensive mangement, reaped a bumper harvest (243 kg hm- 2 ) in 1995, seed-extracting percentage was 6. 2% , and full seed percentage was 62% in cone.
