This paper presents the measurement results and mutual relations of morphological indicators of quality of sycamore maple (Acer pseudoplatanus L.) one-year-old seedlings. The correlation between morphological characteristics was defined in order to determine which of these measured morphological characteristics give the best estimate of quality of sycamore maple one-year-old seedlings without having a destructive effect on seedlings and without requiring an increased range of work. The following morphological characteristics were measured: root collar diameter, height of seedling, weight of aboveground and underground part of seedling in dry condition, number of buds, length and volume of root. Based on measured values the following ratios were calculated: height: root collar diameter, weight of aboveground part of seedling: weight of underground part of seedling and quality index. The root collar diameter and the height have proven to be good indicators of seedling quality but the root collar diameter has a stronger relation with other morphological characteristics. The weight of the underground part of seedling is a better indicator of quality than the weight of the aboveground part of seedling. The best indicator of quality of sycamore maple one-year- old seedlings is the quality index but at the same time it is the most expensive and the most slowly determined indicator which requires the destruction of the seedlings.
