- the first seed orchards of lime trees Tilia cordata Mill. were established in Poland in the Susz Forest district in 1985. Currently, there are 21 seed orchards of this species in the country in order to satisfy the seed demand and preserve the species as well as genetic diversity. due to disease symptoms occurring on Tilia trees and irregular fruiting, an attempt was made to collect information on the problems of seed orchards and their characteristics in Poland. In order to achieve this goal, the average annual seed yield and the total amount of seeds collected in plantations located in Poland were analyzed and compared. each of the selected plantations currently has several dozen different Tilia clones, which mainly serve to preserve the genetic diversity. these orchards are producing seeds from which new tree seedlings are grown and therefore increases in yield are desired. In this study, we analysed orchard location and their seed yield based on the information provided by Forest districts and the National Seed register, in which foresters record data on the collection of seeds as well as breeding difficulties resulting from unsuitable soil types. we were able to determine that the seed yield is primarily influenced by the age of the trees. In addition, trees are exposed to changing weather conditions each year, which may not always be conducive to seed formation. Furthermore, it is during seed collection that disease symptoms or nutritional deficiencies of trees are noticed and recorded, which may not occur every year due to variability in seed formation and demand. In addition, trees are exposed to changing weather conditions each year, which may not be conducive to seed formation.
