Sažetak
The paper analyzes some of the elements of Black walnut seed quality and examines its characteristics. In spring 2004 stratified seed was sown in two ways: on nursery beds and in two types of multiple containers (Bosnaplast 18 and a 35,5x27,0 (16) container with 24 holes). The seed sown in the Bosnaplast 18 container showed the largest germination percentage (55,00 %), followed by nursery germination of seed sown on beds (42,99 %) and in the other type of container (20,83 %). At the end of the current growing season (1+0) the bed-grown seedlings had the largest height (315 mm). The seedlings grown in the Bosnaplast 18 container 18 were on average lower by 61 mm and those from the other container by 67 mm with respect to the bed-grown seedlings. In autumn 2004 non-stratified seed was sown in two ways: with and without cleaning husks. Part of the seed was sown with and part without husks. The nursery germination of the cleaned seed amounted to 91,67 % while the germination of the seeds sown with husks reached 73,00 %. The non-undercut seedlings raised from the cleaned seeds had the largest height (524 mm) at the end of the current growing season (1+0). The non-undercut seedlings raised from uncleaned seeds were on average lower by 185 mm compared to the seedlings raised from cleaned seeds. In both cases the undercut seedlings were lower than the non-undercut ones.
