In this research work first time different colorful varieties (Dark purple, light purple, white, yellow with different shape) of Solanum melongena has been selected to evaluate the intraspecific taxonomic confusions existing to classify the lower order taxa with the help of leaf epidermal anatomical markers. There are many taxonomic confusions were existed due to wide range of adaptability in different environmental conditions. This approach also assists to determine either the different shapes of leaf margins effect on the internal anatomy of long and round fruits of S. melongena. It also provided the similarities and dissimilarities among the related species, but does not provide sufficient knowledge to delaminate the lower order taxa. This approach also leads to choose the other chemical methodology after preliminary evaluation because many characters were same so for careful study and classification we need other genetically and chemical approaches.
Allelopathy is new emerging science, which indicates inhibitory or stimulatory biochemical interactions between the two plant species. Prof. Hans Molisch, a German Plant Physiologist coined this term in 1937. International Allelopathy Society in 1996 broadened its definition as any process involving secondary metabolites produced by plants, microorganisms, viruses and fungi.Agricultural and Biological Systems. Trees are the most dominant form of vegetation in phyto-community Allelochemicals released from trees either in atmosphere (volatilization) or in soil (root exudation and leaching). The allelopathic effects are selective, varies with different trees because these plants have different phytochemicals. Tropical and subtropical areas are rich in tree flora and play vital role in determination of community composition. Therefore it is important to evaluate the allelopathic potential of trees. The analysis should help shed some light on this new and exciting field of research, and will be very useful to plant ecologists.
