Abstract The aims of this study were to evaluate the effects of light and temperature on seed germination and the effect of light on seedling emergence of Clausena excavata, an invasive exotic species. Seeds were incubated at constant temperatures (10 to 40 °C), under continuous white light and darkness. Seedling emergence was evaluated under full sun and canopy shade. There was no significant difference between seeds germinated in the presence or absence of light at temperatures between 20 and 35 °C. Seeds maintained at 20 °C germinated more slowly than other temperatures. Independent of temperature, seed germination was much more synchronised under white light than under darkness. In the field, emergence occurred in both environments, but a greater percentage was observed under full sun. Seedling emergence occurred at the same rate and synchronisation index under both conditions. C. excavata has a high invader potential in open areas and shaded environments. 1. Introduction Biological invasions represent one of the greatest dangers to local and global biodiversity (Washitani, 2001). Little is known about invasive species in Brazil (Petenon and Pivello, 2008). These invasions can cause harm on several levels, affecting individuals (e.g. mortality and growth), population dynamics (abundance, population growth and extinction), the community (abundance of species and diversity) and ecological processes (Parker et al., 1999). In the process of biological invasion, invasive exotic species become dominant in the environment and harm native species and ecosystem functioning, and may even cause the extinction of native species (Pivello, 2007). Invasive species show the most diverse life forms, from herbs to trees, and are present in various ecosystems (Cronk and Fuller, 1995; Seastedt, 2007). Vines and lianas are frequently found along the edges of somewhat intact tropical forests, while colonisation of exotic species frequently occurs in clearings (Dislich et al., 2002). However, according to these authors, disturbed areas and small fragments are more susceptible to biological invasions, since many of these species are helophytes, which are more easily established in these environments. Among some of the characteristics that invasive species have and that promote their success as invaders are fast growth, tolerance to environment stress and high tolerance to environment heterogeneity (Sakai et al., 2001). Disturbances in tropical forests, such as the formation of clearings, have been seen as changes in a habitat. These alterations influence many abiotic factors, such as light availability and presence of undergrowth, which alter environmental temperature and humidity in the canopy gap (Everham III et al., 1996). According to Baskin, CC. and Baskin, JM. (1988), temperature, light, and soil humidity are the most important environmental factors controlling seed germination and seedling establishment. According to Rejmánek and Richardson (1996), optimal conditions for seed germination and seedling emergence are the same as those for optimal growth of a species, since plant survival and invasion are strongly related to mechanisms of germination and emergence. Seed germination studies are important not only for the useful information they contribute to seed technology, but also for their help in understanding the ecophysiology of plant species (Borghetti and Ferreira, 2004). This knowledge helps explain biogeographic peculiarities of many species (Borghetti, 2005) and predict possible environments susceptible to invasion according to specific attributes of invasive species (Cordell et al., 2002). Clausena excavata Burm. f. – wampee, clausena curry – is a semideciduous tree that is native to India, Southeastern Asia and the Philippines. Height reaches between 6 and 9 m, with irregular and open canopy. Flowers are whitish and small, arranged in terminal bunches of 20-30 cm length. Fruits are shiny rose ellipsoid drupes, of 7-10 mm in length, sweetish succulent pulp, and 1 or 2 (Lorenzi et al., 2003) non-dormant seeds (Ng, 1980 apud Baskin, CC. and Baskin, JM., 1998). Medicinal properties of its leaves, bark and roots are known (Wu et al., 1998). In Brazil, its natural regeneration was related as predominant in a recovered forest (Vieira and Gandolfi, 2006), indicating its invasive potential. This species is known in Australia as a weed that is common in Christmas Island vegetation (Green et al., 2004) and as an invasive species in Hawaii (Space and Imada, 2004). The aims of this study were to evaluate the effects of light and temperature on seed germination of Clausena excavata under laboratory conditions and the effect of light on seedling emergence under natural conditions, in order to understand the invasive capacity of this species.. |
