Seed Studies


Studies on variability, germination, desiccation sensitivity and storage of seeds from evergreen tree species were carried out for seeds of Garcinia gummi-gutta, Dysoxylum malabaricum, Myristica fragrans and Dipterocarpus indicus. All the four species are recalcitrant in nature and seeds of G. gummi-gutta are dormant recalcitrant. The viability of G. gummi-gutta and D. malabaricum seeds can be prolonged by storing at 15°C temperature.
