 ABSTRACT

The high economic importance of teak was widely used due to its durability, physical and aesthetic property and also known as king of timber. It has a high demand in international market and distributed throughout India and Southeast Asia. Therefore, the species is now widely planted and the rate of plantation establishment is increasing year by year in India as well as the tropical countries. However, extremely low and erratic germination rates are a significant problem for the teak plantation industry as well as the deployment of planting material from breeding programs. Therefore, five teak provenances i.e. Bardipada, Bhenskatri, Kalibel, Kaprada and Mandvi from Gujarat natural teak forests had been selected for germination test to find out reasons of low germination. Our result showed significant differences (p≤ 0.01) in all the studied characteristics. Drupe germination was maximum at 3rd month (16 %), 6th month (18.50 %), 9th month (23 %), 12th month (35 %), with alternate drying & wetting treatment (17.50 %) and seed germination (55.25 %) in Mandvi provenance followed by Bardipada provenance while lowest in Kaparada provenance. Overall, Mandvi and Bardipada provenances were performed better than all others. The comparison of different germination traits showed the presence of seed dormancy in teak. The major factors for poor germination in teak are physical, mechanical, chemical and embryo dormancy or combined dormancy two or more types such as chemical and embryo dormancy for deployment of superior genetic materials.

Key words: King of timber, Plantation industry, Drupe germination, Seed germination, Seed dormancy
