... usambarensis flowering was observed in all the mature species, however, the fruiting was rare. Seedlings were observed at the Chogoria site. The mean leaf fall was 1.67 (17%) while the Mean leaf flush was 2.33 (33%) ( Table 1). Flower buds formed in January and opened in February while leaf fall occurred between March and June. Leaf buds formed in July and leaf flush was observed in September and October (Figure 2). The environment parameters that influence phenology of a plant were investigated. There was significant (P< 0.05) monthly variation of humidity, rainfall, and radiation. However variations in temperature and wind speed were in significant (P<0.05) during the study period. The mean monthly records indicated the congruence with the phenophases of O. usambarensis (Table 2). The relationship between the environmental factors The regression analysis depicted a linear relationship (P <0.001) between the environmental factors ( Table 3). The relationship between humidity and other parameters were computed with humidity as the dependent variable. There was a linear relationship (P<0.05) between humidity and temperature (Table ...

... usambarensis is partly deciduous. Leaf fall and leaf flush of the deciduous species are annual and strictly seasonal, and leaf fall peaks during the long dry season when the temperature is high. The periods of leaf fall and leaf flush were overlapping. Annual pattern and strong seasonality accords with leaf fall and leaf flush. During the periods of low rainfall and high temperatures the plant shed some of its leaf. The shedding of the leaf coincides with the flowering period. The leaf fall forms the floor layer that enhances moisture conservation in readiness for seed shedding and germination. The physiological process also reduces the chances of transpiration thus concentrating the chemical energy to the seed development. Temperatures, solar radiations and humidity were relatively high at the period of leaf fall for which additionally prepares the plant for leaf flushing at the onset of the rain season (Figure 2). The wind speed was also high during the period to facilitate the leaf fall and spread on the floor surface. The findings agrees with the report by (Justiniano and Fredericksen, 2000) and cloud forest in Hawaii ( Berlin et al., 2000) that Leaf fall of deciduous species in a Bolivian dry forest began at the beginning of the dry season and continued until the beginning of the rainy season. The significant correlation between leaf fall and mean monthly temperature suggests that leaf fall is an adaptation to reduce the effect of water stress in the dry season. The seasonality pattern of peak leaf fall also agrees with reports from the Atlantic Rain Forest Trees ( Morellato et al., 2000) where leaf fall consistently peaked during dry seasons when there was high water stress ( Anderson et al., 2005). Borchert (1984) argued that the timing of leaf fall is controlled by the water status of the ...
