Abstract
Seed productivity and seed quality determine the survival of the species in the places of its growth. Evaluation of the seed maturity of some species of the genus Larix Mill. growing in the arboretum of the Botanical Garden of the St. Petersburg State Forest Engineering University named after S.M. Kirov is an important indicator of the success of the introduction of these species in the conditions of St. Petersburg. This report is devoted to the study and evaluation of the seed quality of representatives of the genus Larix using a modern X-ray method. It was showing that seeds of different quality forming at different tiers; the percentage of good, mature, viable seeds does not exceed 10-15. This figure could be higher if the seeds were not affecting by the larch wasp Eurytoma laricis.
