Abstract
IT is well known that seedling trees of Pinus sylvestris, in common with those of many other woody species, pass through a juvenile period, during which no reproductive organs are formed. The first female cones appear at the age of about seven years, while male cones are not usually formed until several years later. These male cones generally appear first on the lower, older branches.
