ABSTRACT:
Lantana camara is a common wild shrubby ornamental and hedge plant growing from plains to an elevation in surrounding forest of Chhattisgarh. Lantana with red flowered are thought to be the most toxic but some white/ pink flowered varieties can also be highly toxic. Allelopathy is a complex ecological process and biological phenomenon that depends upon accumulation and decay of litter, soil characteristics and climate. The aim of present work to observed the allelochemical effect of Lantana on forest vegetations of Bilaspur Chhattisgarh which inhibit the plant diversity and displace the native vegetation. The present work was done in forest and waste land of Bilaspur Chhattisgarh. Lantana camara seed, fruit, ste and leaf parts are have strong allele-chemical effect. Allelopathic influences the growth, survival, and reproduction of other biological organisms. In dense thickets, lantana excludes native species through smothering and allelopathic effects (ie toxicity to other plants). It dominates under-storey's prolongs succession and reduces biodiversity. Lantana plays a role as a persistent weed and has the potential to block succession and displace native vegetation and reducing biodiversity by allelo- chemicals. Allele-chemical observations of Lantana inhibit the germination and growth of plants which grows surrounding lantana clumps. In present study will be discuss the Lantana camara play as allelopathic effect on the germination and growth of various plant species and can establish in natural ecosystems, open and bare areas etc.
