There is usually a great flush of germination after tillage of the soil during the spring.Finally, central achenes were more likely to be removed from the infructescence when tested with an artificial dispersal agent, as 40.4% of the infructescences tested had achenes removed from the central positions.Analysis of the germination percentage confirmed the presence of two distinct classes, formerly defined as short and long achenes.Leaf area, number of shoots and number of flowering heads increased considerably with increasing nitrogen.Seedlings originating from short achenes showed lower survival rates and initial slower development than those originating from long achenes ( Forsyth and Brown, 1982 ).Common Name of Blackjack Oak and Teak Scientific name of Blackjack Oak and Teak is the name accepted by scientists worldwide.Blackjack Oak in Greek: Blackjack Oak Tree Teak in Greek: Teak.Learn about medicinal plants and herbal remedy uses,.

A coffee-foliage feeding noctuid moth can spread by using B. pilosa as a host ( Bardner and Mathenge, 1974 ).The phenomenal spread and colonization of Bidens species is due partly to their effective pollination mechanisms and their distinctive dispersal adaptations, which allow seed distribution by humans, animals, wind and water ( Holm et al., 1997 ). In the Philippines, it has been reported as a rice crop seed contaminant ( Elliot et al., 1993 ).
