Seed dormancy, storage behavior and germination of an exotic invasive species, Lantana camara L. (Verbenaceae).

摘要: Lantana camara is a native shrub to West Indies. It has been introduced several tropical and sub countries. Now this plant become invasive in these countries including Sri Lanka. The objective of study was gather basic information on seed biology L. aid controlling it. Seeds were collected from numerous shrubs Kandy Ambalangoda. Seed moisture content (SMC), imbibition germination untreated manually scarified seeds determined. Effect dormancy breaking treatments studied. Length, width, mass, SMC germinability developing examined. Moisture Content (12.9%) suggested that are orthodox. Both imbibed water similar rate. None the germinated light/dark constant dark conditions. Further, contained fully developed embryo. Thus, it concluded have physiological dormancy. Only few responded suggesting deep According ontogenical experiments, attained maturity dispersal by 4 th 5 week pollination, respectively. can be onset occur before maturity, where 0% at any stage. showed potential retain soil bank. control invasion, suitable methods develop deplete
