Abstract - Issue Jan 2006, 27 (1) BackGrowth responses of scots pine
seedlings grown in peat-based media amended with natural zeolite ?(Received: 18 October, 2004
; Accepted: 12 May, 2005) Abstract : Zeolite has many good features that makes it very attractive for
nursery use as a growing media over others. This study was designed to
investigate influence of different growing media and their mixtures (with zeolite and without zeolite) on
morphological characters of scots pine seedlings.
Twenty-one treatments of varying amounts of peat, fine pumice, coarse pumice,
river sand, perlite and river sand were established
and were sown with
scots pine seeds. At the end of first growing period,
30 seedlings from each treatment were harvested and measured for height (SH),
root collar diameter (RCD), root dry weight (RDW), stem dry weight (SDW) and
total dry weight (TSDW). These parameters varied significantly among treatments
and were lower in zeolite added media. SH negatively
correlated with Na and K content and C/N ratio of growing media but positively
correlated with Mn content of media. SDW
and TSDW had positive correlation with N, Fe, Mn,
total porosity and loss of ignition, and had negative correlation with pH, Ca,
Na and K content.? Key words: Scots pine, Seedling, Zeolite, Growing media, Morphological character. Copyright
