Tóm tắt

The endemic species Pinus krempfii Lecomte in Bidoup National Park – Lam Dong Province, Vietnam is monopodial woody within morphogenesis and architecture based on Rauh’s model. With a monopodial structure, it is featured with rhythmic branching, lateral flowering, radial symmetry, and the architectural unit within 5 axes. On morphological development, the P. krempfii consists of three main stages: seedling, sapling with five phases getting along with the arising of the first axis to 5th, and the adult carrying reproductive organs and a complete architectural unit. Respectively, the transition of needle morphology and size is observed: wide, slender falcate, bundle with two leaves from a short shoot only on seedling and sapling trees. The adults, in addition, bundle with smaller, lanceolate leaves from a short shoot spirally. Essentially, the modification of leaves corresponds to the stages of morphogenesis: the size of leaves decreases with stages on average
