Yield of cotyledonary embryos of hybrid larch (Larix × eurolepis Henry) after eight weeks of maturation per g FW of embryogenic culture in three different culture systems: clumps of embryogenic culture on solid maturation medium, suspended embryogenic culture plated onto filter paper placed on solid maturation medium, and TIBs. Data represent mean ± SE from three replicates. Different letters indicate significant differences at P < 0.05 according to Duncan's multiple range test (n = 3).
