Abstract

The present study was conducted to find the influence of age of the seedling, drupe size and earliness of germination on the root growth potential of teak stumps. Teak drupes graded into diameter classes of 9-12, 12-15 and 15-18 mm, germinated and weekly germinants up to four weeks were planted in split plot design with drupe size as main plot and time of emergence as the sub plots. The drupe size and earliness of germination significantly influenced the seedling traits. Root growth potential of the stumps prepared from six and twelve month old seedlings were assessed. The analysis of variance of root growth attributes indicated that the interaction effects of drupe size, earliness of germination and age was significant in the case of biomass production of lateral roots (p=0.01). In stumps from six month and one year old seedlings, the highest root biomass observed in the stumps belonging to large size grade and first week of germinants. While selecting the seedlings for stump preparation, screening of seedlings based on the drupe size and earliness of germination as well as using one year old seedlings is essential or the successful establishment in the field.
