Reproductive organs were induced in 2-year-old Pinus griffithii X Pinus strobus seedlings by a combination of temperature and fertilizer treatment, and a number of the microsporangiate strobili changed into hermaphroditic strobili. Similar results were observed in three successive years. Sex transformation in some instances progressed far enough to produce viable seed following pollination of bisporangiate cones.
