Abstract:
In the present study fruits were collected from the seven natural populations of teak from Ponnampet, Mudigere, Shivamogga, Sirsi, Kiravathi, Dandeli and Bidar. Nursery experiment was carried out during April 2004 to June 2005 at Agriculture Research Station (Paddy), College of Forestry Campus, Sirsi. Teak populations have showed the significant variations among different locations for various fruit and seed characteristics. For seed length and seed breadth highest was found in the Ponnampet population 5.57 mm and 3.96 mm respectively and least was observed in the Bidar population 5.31 mm and 3.63 mm respectively. Shivamogga population has showed highest for the seed thickness with 2.51 mm, followed by Dandeli and Mudigere 2.42. Whereas least was found in the Bidar population (2.33 mm). The germination per cent of teak in different location was poor (<14%) may be due to poor seed filling which is a major problem in teak. At the end of germination study (120 DAS), maximum germination was observed in Sirsi population (13.1%), followed by Kiravathi (11.10%). Both Shivamogga and Ponnampet recorded low germination (6.3%). Highest total biomass was observed in Kiravathi (86.4 g) followed by Dandeli (80.8 g) and lowest was observed in Ponnampet (38.0 g). The results revealed a significant positive association of collar diameter with shoot biomass (r=0.952) and number of lateral roots (r=0.863). Similarly, seed breadth showed significant positive association with 100 fruit weight (r=0.549) and fruit diameter (r=0.544).
