초록

벚나무류 (Prunus subg. Cerasus)는 가로수 및 조경수로 전국에 가장 많이 식재하지만 외형으로 식별이 어려워서 종별 수량은 관리되지 않고 있다. 다양한 벚나무류가 식재된 성남시 분당구 분당중앙공원과 인접 지역의 식재유형과 종 구성 등의 실태를 파악하고, 조경수목 식재 관리 필요성을 논의하고자 하였다. 벚나무류의 개화기인 2021년 4월에 성남시 분당구 일대 약 6 km2 내에 식재된 벚나무류 총 5,866주를 조사하였다. 이 중 5,744주는 11분류군으로 구분하였으며, 나머지 122주는 복합적인 외부형태 특징을 보였다. 소메이요시노벚나무(Prunus ×yedoensis Matsum.)가 가장 높은 비중(52.1%)을 차지하였고, 잔털벚나무(P. serrulata Lindl. var. pubescens (Makino) Nakai), 벚나무(P. jamasakura Siebold ex Koidz.) 등의 순으로 나타났다. 제주도에 자생하는 왕벚나무(P. ×nudiflora (Koehne) Koidz.)는 본 조사에서 확인되지 않았다. 미소한 특징으로 구분되는 벚나무류의 식별을 돕고자 주요 조경용 벚나무류 11분류군에 대한 검색표를 제시하였다. 벚나무류는 자연 상태에서도 빈번하게 종간 잡종을 형성하는 것으로 알려져 있다. 외래 벚나무류와의 잡종화와 이에 따른 유전자 이입에 의해 자생종의 유전적 고유성이 손실되는 것을 막기 위해서는 자생지 주변의 식재 수종 관리와 원산지 추적이 필요하다.

Prunus subg. Cerasus is the most planted street and landscaping tree in South Korea, but it is difficult to identify species according to their macro-morphologies, leading to problems when attempting properly to manage species quantities. The purpose of this study is to understand the current status of plant types and species compositions in Bundang Central Park in Bundang-gu of Seongnam City and to discuss the necessity of the management of landscaping tree planting. In April of 2021, during the cherry blossom season, a total of 5,866 planted cherry trees were investigated within an area of 6 km2 of Bundang-gu in Seongnam City. As a result, 5,744 trees were sorted into eleven taxa, but the remaining 122 trees were not determined due to their complex morphologies. Prunus ×yedoensis Matsum. accounted for the highest proportion (52.1%), followed by P. serrulata Lindl. var. pubescens Nakai and P. jamasakura Siebold ex Koidz. P. ×nudiflora (Koehne) Koidz., a plant native to Jejudo Island, was not found in this survey. In order to help identify cherry trees based on micro-morphologies, an identification key was presented for the eleven taxa planted as major landscaping trees. It is known that cherry trees frequently form interspecific hybrids in nature. In order to prevent a loss of the genetic originality of native species due to hybridization and gene introgression from foreign cherry trees, it is necessary to manage planting species near the habitats of native taxa and track their origins.
