Evaluation assesses seedling growth and stump quality in teak drupes across various forest types, indicating significant provenance differences.
Teak drupes were collected from seven geographical locations representing four forest types in India—dry deciduous, moist deciduous, very moist deciduous, and semi-deciduous—to evaluate provenance variation in field emergence, seedling growth, and stump quality. Seed filling percentage was assessed through a cutting test. Pre-conditioned drupes were sown in nursery beds (5 m²) containing red earth, sand, and farmyard manure (2:1:1) under a randomized block design with five replications. Seedling emergence was recorded up to 28 days and at monthly intervals up to six months after sowing. Growth and quality parameters were measured at six months. Results indicated significant provenance variation, with drupes from the Telangana (Jannaram) provenance producing the highest seedling emergence per m² and the greatest number of plantable stumps compared to other provenances.
