Abstract: The study was conducted with a view to standardize the propagation techniques in Tea tree (Melaleuca alternifolia L.). During the trial, two type of propagation method viz., vegetation propagation through different type of cuttings and seed propagation treated with various plant growth regulators were done. Observations were made on sprouting percentage, number of sprouts per cutting and survival percentage for vegetative propagation and in seed propagation study, germination percentage, days taken for germination and survival percentage were recorded. At 30 days after planting, sprouting percentage (49.45 per cent) was recorded maximum in hardwood cuttings treated with IBA 1500 ppm (T1) and highest number of sprouts per cutting (8.78) in control (T3). No callus formation and rooting were observed in any type of cuttings and treatments. In seed propagation, soaking the seeds in GA3 1000 ppm (T1) for 30 minutes resulted in higher seed germination percentage both in petridish (laboratory condition) and pot sowing (35.63 and 33.33 per cent respectively) and was significantly superior to all the other treatments. Due to toppling of seedlings during misting operation and subsequent drying up of seedlings, no germinated seedlings survived.
