Book excerpt: Excerpt from Seed Stored in Cones of Some Jack Pine Stands, Northern Minnesota In both the 40-year-old and 70 to 80-year stands, the number Of cones produced increased with d.b.b. The limited data available also indicated that within a given stand, cone production increased as crown position increased in dominance. The amount Of viable seed stored in the cones varied from per acre in the 40-year un thinned stand to for thinned timber of this age. Intermediate were 70 to 80-year jack pine with and the plantations with per acre. This is a range of to pounds of germ inable seed, an amount which would be muchcones. But since there were more Older cones on the trees, they contributed almost a third of the viable seed. The lower yield Of viable seeds in Older cones was due in part to the fewer total seeds they contained and in part to the presence Of an appreciable number Of dead seeds, for empty seeds were no more numerous here than in young er cones. Dead seeds were Of no consequence in any Of the other cone lots tested except in one from a 130-year-old tree in which they amounted -to 7 percent.
