Abstract:

The study of various periodic behaviours of the phenology has great significance because it not only provides knowledge about the plant growth pattern but also provides the inferences on the effect of environment and selective pressure on flowering and fruiting behaviour. In the present study, an attempt has been made to record such data regarding periods of leaf fall, flowering and fruiting. This was done for a period of one year for 50 species of course which were somehow having medicinal properties and it was carried out in the Pachamalai hills of Tiruchirappalli district, Tamilnadu. In the study the leaf fall peak period was found in last part of January - February, new foliage peak period in the month of February-March where as flowering and fruiting activity peak period was found during the month of March - April. The present paper will be helpful to give inferences in future whether the of climate change are giving pressure on the periodic behaviour of plant species. Changed phenological behaviour of plant species indicates the losing of plant diversity of the district in a critical level.
