Abstract: Researches on the fruiting pattern and its fluctuation of Larix gmelinii have great significance in seed collection and forest regeneration.As the investigations indicate,the fruitage of Larix gmelinii in 1989 is in mid-level.For trees with dbh over 16cm,60% are fruited.The fruiting rate and seed production increase with increasing dbh,and for trees with dbh over 24cm,they are significantly greater.Serious seed infestations by insect pests are also found .The period of seed dispersal is quite short.It begins at the first ten days and ends at the last ten days of September.
