Effects of Intra-Plant Competition on the Ensuing Spatial Branching Patterns of Straits Rhododenron

Abstract:
The ensuing plant branching patterns were studied at three planting densities 1, 2 and 3 plants per wooden box, raised until maturity. Circular statistics were used to represent the evolving spatial distribution of branches along density gradients of the translation with certain assumptions. The position of each branch was characterized by three parameters: horizontal rotation (φ), vertical rotation (θ) and translation. The values of φ were measured within 45° angle using a circular protractor, divided into 8 angular sectors oriented clockwise, while φ was measured from the geographical north direction (0°). The translation was registered from 1 to 5 categories. The distribution φ was uniform, but the distribution θ was non uniform. The former was distributed symmetrically in plants at densities 1, 2 and 3 with respective mean direction values of 52.3°, 47.8° and 41.8°. The mean direction of the angle θ was different between plants at different densities and translations, whereby branches became progressively more erect with increasing density regimes from 1 to 3 and from the base to the top of the canopy. The registered mean direction of each translation from 1 up to 5 from the base were 60.2°, 49.7°, 40.1°, 30.5° and 22.5°, respectively.
