EFFECT OF ACCELERATED AGING ON GERMINATION AND SEEDLING VIGOUR OF TEAK (<em>TECTONA</em> <em>GRANDIS</em>)

Abstract

A study was made to assess the influence of accelerated aging of 10-month-old teak fruit stones on seed germination and seedling vigour. Aging was carried out in an aging chamber maintained at 100% RH and 40 °C. The fruit stones aged for 13 days showed 53% germination against 18% in the control in normal open condition after 28 days of sowing. Fruit stones in mist chamber gave 39% germination against 14% in the control after 11 days aging. Further forced aging enabled early germination which was associated with more seedlings per 100 fruit stones and better seedling vigour under both test conditions.
