Abstract :In the present study, effects of vermicompost treatment tried to be determined on some morphological and physiological seedling quality characteristics of one – year Scots pines. Experiments were set according to random plots experimental design including 14 trials with 3 repetitions. With this aim, seeds obtained from seven different sites (origins) of mixed Scots pine stands which naturally grow in the Western Black Sea Region of Turkey were used in the experiments. At the end of the vegetation period, important physiologic and morphologic parameters of seedlings in the plots, SH, RCD, TDW, RDW and total N rate were detected. After that, RI, V and QI rates, each of which is also important rational indicator in seedlings for height, root collar diameter and weight balance, were calculated with the help of morphological data. Effects of VC treatment were found to be statistically significant on all the development parameters measured in seedlings in seven origin groups. It was determined in all morphologic parameters that the best development rate was observed in Goktepe originating seedlings in both VC treatment and control groups while Geyikgolu originating seedlings showed the least development performance. It was observed from the correlation analysis that there is a positive relation between morphologic and physiologic quality criteria. It was also determined according to the results of multivariable regression analysis that elevation of the sites where seedlings were picked up was more effective on the development of seedling development than the aspect of the sites. Results of the study were found to be convenient with the related literature and showed that VC treatment contributed positively to the development of Scots pine seedlings taken from seven different origins.
