dc.description.abstractGarcinia gummi-gutta is one of the economically important recalcitrant species which is rich in Hydroxycitric acid (-HCA), an important biologically active plant metabolite used as an anti-obesity drug. Seeds of Garcinia gummi-gutta loose its viability within few days under natural conditions, when the seed moisture content reduces below a high critical value. Germination of this tree is also very poor and late. The present investigation was taken up in College of Forestry, Sirsi in 2013-2014 on Garcinia gummi-gutta in order to enhance the quality for better and quick germination. The maximum germination percent (34 per cent) and moisture content (41.97 per cent) was observed in freshly decoated seeds. The moisture content of 28.84 % was found to be critical moisture content for seeds, as below this germination was zero. The maximum mean daily germination (0.19), peak value (0.22) and germination value (0.04) was recorded in fresh decoated seeds. Out of eleven different pre-sowing treatments tried, the maximum germination percentage (86.33 per cent) was recorded in decoated seed treated with GA3 50 ppm for 12 hrs as compared to other treatments. The other higher quality indexes viz., mean daily germination (0.48), peak value (0.58), germination value (0.28), shoot length (13.33 cm), root length (13.43 cm), seedling height (26.76 cm), seedling dry weight (1.26 g) and seedling vigour index (2311) also recorded in this treatment. During six months of storage, the seeds stored in ash treatment recorded maximum germination at the first month of the storage and decline in germination was noticed with advancement in the storage period. Germination per cent in control was negligible after 3 months of storage. Among the all treatments the maximum germination percentage was maintained in pet jar upto sixth months of storage.en_US
