This manual contains detailed biological descriptions of the major characteristics of some weed species found in Trinidad, including Axonopus compressus, Brachiaria mutica [Urochloa mutica], Commelina diffusa, Cyperus rotundus, Echinochloa colonum [E. colona], Eleusine indica, Parthenium...

Oilseed rape MON 88302 was developed by Agrobacterium tumefaciens-mediated transformation to express the CP4 EPSPS protein, which confers tolerance to glyphosate. The molecular characterisation of oilseed rape MON 88302 did not raise safety issues. Agronomic and phenotypic characteristics of...

Jatropha curcas L. is a tropical tree belonging to the Euphorbiaceae family with oil-rich seeds that are currently used as a source of biodisel. A better knowledge of the reproductive ecology is imperative for yield optimisation and invasiveness risk assessment. Insight in the diversity and...

Urban areas are among the most important centres of invasive plant species distribution due to their richness in alien species. Because of that, a detailed floristic analysis of perennial flowerbeds was conducted in the central parks of Belgrade. A total of 53 perennial species were found, of which ...

Genetic and environmental and reproductive factors can play a vital role in the invasion success of plant species. In fact, recent studies indicate that plant reproductive systems are an important determinant of invasion success. To test these hypotheses, this study used two independent...

In view of the significant contribution of phenotypic plasticity in survival and spread of invasive species in heterogeneous adventive environments, present study was carried out on natural populations of Anthemis cotula L. (Stinking mayweed) growing in habitats that differ in disturbance. The...

Weeds cost Australian agriculture over $4 billion annually through factors such as yield loss and management costs (Sinden et al. 2004). Although not quantified, the impact of weeds on natural ecosystems has also been recognised as a serious threat to biodiversity. Consequently there is a need to...

Senecio inaequidens DC. is a rapidly spreading plant invader in Europe. In its native range, it occurs at two co-existing diploid and tetraploid cytotypes. To date, only tetraploids are reported in Europe, even though invasive diploids were recorded in other parts of the world. We compared native...
