Quality indicators of Larix L. seeds in plantations of Ternopil region
Journal Title: Лісівництво і агролісомеліорація - Year 2013, Vol 122, Issue
Abstract
The quality indicators of compatible seed lots of Larix Mill. were studied (purity, weight of 1000 seeds, germination, germination energy, pathogen contamination) based on the analysis of medium-sized samples from the Lviv State Zonal Forest Seed Inspection during 1990–2012. We found that in forest plantations of the western region of Ukraine the quality of Larch seeds is generally high. Average value of a species seeds technical germination is 32,3–38,8 % with the sign of clear tendency towards germination reduction during the study period. Among the 773 compatible lots the seeds of 1, 2 and 3 quality classes are distributed as follows: 46, 37 and 16 % respectively, amongst which the substandard seeds reach only 1 %
