Lopping and soaking in seeds of noni (Morinda citrifolia L.)

The study aimed to test the germination of seeds of noni under different soaking times, with and without the seed emerges. For this, an experiment was installed in a greenhouse in a completely randomized design with 10 treatments and 4 replicates of 25 seeds, being composed of: 1. Witness 2. Seeds with the blunt side opposite the embryo 3. Intact seeds with 12 hours of soaking, 4. Intact seeds with 24 hours of soaking, 5. Intact seeds with 36 hours of soaking, 6. Intact seeds with 48 hours of soaking; 7. Seeds with cutting with 12 hours of soaking; 8. Seeds with cutting with 24 hours of soaking; 9. Seeds with cutting with 36 hours of soaking and 10. Seeds with cutting with 48 hours of soaking. The characteristics evaluated were: percentage of emergence, speed of emergence index, seedling height, root length and weight of the dry mass of seedlings 46 days after the experiment. There were significant differences between the different times of soaking and treatment 10 (cutting with 48 hours of soaking) who obtained the best results for the percentage of emergency and emergency speed index and dry weight. The height of the seedling, one treatment (control) was the highest, while in treatment 2 (blunt) registered the largest root length. Although the witness did not differ, the best treatment was the use of blunt + 48 hours of soaking.
