Studies on cone analysis and early growth of pinus densiflora f multicaulis uyeki

Studies on cone analysis and early growth of pinus densiflora f multicaulis uyeki

Research Report of the Forest Genetics Research Institute (25): 53-55

Cone were analysed and early growth in nursery was measured to get information needed for seed production and nursery management of Pinus densiflora f. multicaulis Uyeki. The results were as follows. 1. The number of seed potential and filled seed per cone were 47 and 35, and germination rate in nursery was 76%. 2. /The mean number of cotyledon was 6.2 and mean length of cotyledon and hypocotyle were 3.3cm and 1.2cm. 3. The mean height, diameter at root collar, number of branch and branch diameter were 10.9cm, 7.2mm, 13.9 and 1.4mm, respectively.
