Variation of the Number of Empty Seeds per Cone in Pinus koraiensis Sieb. et Zucc. <Jour. Kor. For. Soc. 65:24-30 1984> Senior author Sang-Keun Chon
The average number of empty seeds per cone on the mature tree was 10.03±0.61. The ratios of empty seeds to total seeds and to full seeds were 7.38±0.35% and 8.42±0.49%, respectively in average. The number of empty seeds per cone and the ratios varied with the site condition, fruiting year, and individual tree. The contribution rates of these sources of variance to the number of empty seeds per cone were 3.50%, 8.06%, and 55.41%, respectively. No co-relationships were found between the amount of empty seeds in number or ratio and the cone production, and the D.B.H. of mother tree. However, both the number of empty seeds and the ratio of empty seeds to total seeds showed significant positive correlations with the number of one-year-old cones per tree.
Key words: Pinus koraiensis, seeds, empty seeds
