THE VARIATION OF PHENOLOGICAL TRAITS AMONG LATITUDINAL AND ALTITUDINAL SIBERIAN STONE PINE (PINUS SIBIRICA DU TOUR) ECOTYPES
The comparative analysis of seasonal shoot growth cycle between latitudinal and altitudinal Siberian stone pine ecotypes growing under the homogeneous environments of clone archive was conducted. Among latitudinal ecotypes differences in shoots and needles growth dates and duration were more significant than those among altitudinal ones. More significant differentiation among latitudinal ecotypes, probably, was related to their development not only contrast climatic conditions but in different photoperiodic regime in contrast to altitudinal ecotypes.
