Influence of Seed Age and Mechanical Treatments on Seed Germination in Calophyllum inophyllum Linn

Calophyllum inophyllum Linn., is one of the multipurpose tree species of coastal area and commercially used as Tree Borne Oil seeds (TBOs). In the study, fresh and one year stored seeds were examined for germination pattern by using some mechanical treatments. One year stored seeds did not germinate in control, whereas fresh seeds resulted in 40% germination in control. Decoated seed fetched the germination improvement up to 88.3% in fresh seeds and 20% in one year old seeds. Seed thickness and seed length showed significant positive association with seed germination. The study revealed that it is better to use fresh seeds followed by de-coating of seeds to achieve higher germination in C. inophyllum.
