Effects of cultural treatments, seedling type and morphological characteristics on survival and growth of wild cherry seedlings in Turkey

Abstract

Wild cherry (Prunus avium L.) is receiving increasing attention from foresters in Europe and Turkey for its fast growth, highly-valued wood and benefits for wildlife and biodiversity. Little documentation may be found concerning the selection of appropriate cultural treatments and the quality and types of seedlings used for wild cherry plantations. This study reports the effects of various combinations of intensive cultural treatments (including weed control, soil tillage, and fertilization) and seedling types on early growth, survival, and nutrition of one-year-old wild cherry seedlings out-planted on four different sites in the western Black Sea Region of Turkey. After two years, early seedling survival and growth were clearly enhanced for potted seedlings. For bare-root seedlings, initial seedling root-collar diameter and height successfully correlated with survival two years after planting. Seedlings with a root-collar diameter of 6-8 mm and height of 60-70 cm demonstrated the best survival rates in the field. The wild cherry seedlings were shown to be highly sensitive to herbaceous weed competition early in their establishment, warranting effective weed control. When used in addition to weed control, neither intensive fertilization nor soil tillage treatments significantly increased seedling survival and growth two years after planting. Therefore, intensive site preparation, as well as fertilization, are not recommended at this stage for planting sites without severe nutrient deficiencies.
