Quality indicators of Abies alba Mill. seeds in plantations of western regions of Ukraine
Journal Title: Лісівництво і агролісомеліорація - Year 2013, Vol 123, Issue
Abstract
The quality indicators of compatible seed lots of Abies alba Mill. were studied (purity, weight of 1000 seeds, germination, pathogen contamination) based on the analysis of medium-sized samples from the Lviv State Zonal Forest Seed Inspection during 2000–2012. We have found that in forest plantations of the western region of Ukraine the quality of Abies alba Mill. seeds is generally high. Average value of a specie seeds technical germination is 25,5–43,5 %, weight of 1000 seeds is 49,4–56,9 g with the sign of clear tendency towards germination reduction during the study period. Among the 1308 compatible lots the seeds of I, II and III quality classes are distributed as follows: 29, 34 and 35 % respectively, amongst which the substandard seeds reach only 2 %
