“…All the scarification treatments weakened the seed coat of the tamarind thereby, making it water permeable. This is in agreement with the findings of [10] who affirmed that scarification treatments could overcome physical dormancy of seeds by causing many randomly located cracks in the seed coat, which then function as sites of water entry.…”

The purpose of this research was to determine the appropriate methods of breaking seed dormancy, level of water uptake, and the influence of gibberellic acid on the early growth of Tamarindus indica seedlings. The scarification methods used included: concentrated sulphuric acid (H2SO4), manual scarification, flaming, hot and cold water treatments. The experiments were conducted in the laboratory on Petri dishes and in potting media. GA3 was used to optimize the production of seedlings by spraying the solution on the foliage. The treatment for 10 minutes with concentrated H2SO4 gave the maximum germination percentage and water uptake (80.41%). GA3 enhances the growth of the seedlings by increasing the height, the number of leaves and stem girth at eight weeks after sowing. In conclusion, all the scarification treatments applied to the seeds of T. indica proved effective. The ten minutes treatment with concentrated H2SO4 was the best treatment for breaking seed dormancy of T. indica. And gibberellic acid enhanced early and fast seedling growth as it increase height, number of leaves and stem girth of T. indica.

Indigofera zollingeriana is one of Indigofera species distributed in Indonesia and known as forage crop. Seed is an important factor which influences cultivation of I. zollingeriana due to low seed germination. The objective of the research was to determine the effect of different pre-treatment as chemical scarification (98% of H2SO4, 0.3% of KNO3, glycerine (C3H8O3) at 70 o C), hot water at 70 o C with different duration of immersion or soaking and mechanical scarification using sand paper on I. zollingeriana's seed germination. Pretreatment had significant differences and improved germination percentage, germination speed index and shoot length. The positive correlation was noted between germination percentage and germination speed index.

“…In order to initiate the germination process, it is necessary to have a rupture in this impermeable layer; this can be done artificially by mechanical scarification or with corrosive chemical substances, such as acids. For example, the application of sulfuric acid for five minutes breaks the dormancy of Stylosanthes humilis seeds (Chaves et al, 2017).…”

Physical, physiological and anatomical changes in Erythrina speciosa Andrews seeds from different seasons related to the dormancy degree

et al. 2018

Dormancy, a process that allows seeds to survive in adverse environments, needs to be broken for germination to start, for example, by the disruption of the impermeable layer of seeds. Mature seeds of Erythrina speciosa present seed coat impermeability, whose degree depends on the year of production. The objective of this study was to analyze the physical, physiological, anatomical, and ultrastructural seed coat modifications, according to the environmental conditions in which seeds were produced, as well as the seed sensitivity to treatments as for breaking dormancy. E. speciosa seeds were collected for six years in a row and were analyzed as for dormancy degree. Moreover, chemical scarifications by different immersion times were applied on seeds from two production years, as well as mechanical scarification, which was an efficient methodology to overcome dormancy. Different immersion times by acid scarification were necessary to break dormancy in each harvest year. It was possible to conclude that the climatic conditions under which the mother plant is submitted can influence the dormancy degree of E. speciosa seeds, but the expected anatomical changes between dormant and non-dormant seeds were not found in seeds from this species.
