Identification of Juvenile Duration and Morphological Changes in Leaves and Stems after Transition to the Adult Phase in Native Trachelospermum in Korea

This study was conducted to determine an index of phase changes in Trachelospermum jasminoides leaf and stem morphology identify the timing juvenile-to-adult transition. Fifty percent stems showed thigmotropism fall 5th year after sowing. In May 6th year, had adult leaves 33% bloomed, indicating that juvenile period for native T. requires at least 5 years prior blooming. As a result targeting 13 regions Korea shape during phases, greater than adults cultivation test districts most (10) regions. Young were lanceolate with distinct veins, whereas long oval-shaped, inconspicuous morphological changes. shows phases can be distinguished by stems, vein pattern, relative size leaves, index. identification method could adapted into discriminate jasminoides. According dendrogram PCA, there no clustering region harvest elements similar. addition, PCA area highest contribution rate among first main components used as indicator distinguishing
