MOISTURE CONTENT AND TEMPERATURE EFFECT ON THE CONSERVATION AND GERMINATION OF Mimusops kummel .....

Many tree species and their ecosystems are currently threatened by anthropogenic and climate-change-related issues. Experiments on seed storage and germination responses of tree species are therefore critical for determining appropriate conservation techniques. This study intends to discover optimal seed pretreatments and investigate the effects of moisture content (20.6, 7.06, and 3.7 percent), storage settings (room temperature, +4C, and +10C), and varied storage periods over 12 months on Mimusops kummel A. DC seed germination and storage behaviour. Seed germination varied considerably (P =.01) from 30% (hot water treatment) to 100% (cold water treatment) (sand sowing media). On seed germination and storage behaviour, significant impacts of seed moisture content and storage temperature (P.001), as well as the interaction effect of these two parameters (P =.004), were observed. Although the storage length had no effect on the germination percentage of seeds, the most optimal values of seed moisture and storage condition for long-term storage are 3.7 percent moisture content and –10 °C temperature, respectively. Similarly, for interim storage, a seed moisture content of 7.06 percent and a storage temperature of +4°C are ideal. M. kummel seeds have a traditional storage habit, which means they may be stored for a long time without losing viability. The seed of M. kummel is non-physiologically dormant, which means it can germinate readily in a controlled setting using sand or filter paper media. Cold storage improves germination as well.
