Effects of planting time on survival and early growth of containerized and bareroot scots pine seedlings in Tortum, Erzurum

In this research, the effects of planting times (spring and summer) and 5 seedling types on seedling performance (survival, height, diameter, diameter increment and height increment) were investigated in Tortum, Erzurum-Turkey. Seedling morphological characters (height, diameter, shoot dry weight, root dry weight) were determined before planting, and it was found that they were affected by seedling types. Seedling type and planting time affected seedling performance in this semiarid site, Tortum, Erzurum. Seedling survival and seedling height were the highest in spring planting. Seedling height and seedling root collar diameter were the highest in 2+0 containerized seedlings. It might be concluded that in semiarid areas 2+0 containerized seedlings might be planted in spring compared to autumn planting.Keywords: Afforestation, seedling performance, seedling morphology, containerizedseedlings, Scots pine.
