“…Sanyang et al (2008) concluded that seeds of A. senegal treated with hot water for 10 min showed early germination. Seeds of Albizia julibrissin treated with hot water, soaking in warm water at 40°C and 50°C, and soaking period were 1-6 h. Seeds soaking in 40°C and 50°C showed 86-91% germination (Merou, 2011). Ixora seeds treated with hot water and showed 85% germination, this result close to Albizia results.…”

Ixora coccinea L. is ornamentally and medicinally important coastal plant also associated with mangroves of Sindhudurg and Ratnagiri district. In the present study, seeds of I. coccinea were treated with cold water, 50°C hot water, germinator solution, and also 100, 200, and 500 ppm gibberellic acid (GA). Germination percentage was measured everyday until no germination was observed. Data were analyzed using analysis of variance and the significant mean difference in pair of treatments was analyzed using t-test. Seeds of I. coccinea treated with 100 ppm GA showed highest germination percentage, i.e., 90% followed by hot water treated seeds and it showed 85% germination. Seeds were treated with GA, hot water, germinator, and soaking in cold water showed significant difference in between treatments (P < 0.05). Overall, the results suggest that 100 ppm GA and hot water treatment used for enhance the germination of I. coccinea seeds.

“…Soaking seeds in cold water for 1 to 6 days had no significant effect on increasing the germination percentage, germination rate, and seed vigor index. Unlike our present results, Merou et al (2011) reported that seed immersion in tap water for 2 days resulted in 73% germi- Fig. 4.…”

“…The reason behind the low seed germination reported by them, compared to that of the present research, can be attributed to both the different experimental conditions (planting the treated seeds in trays containing sterile sand and keeping them in a growth room under a temperature range of 20-25 °C) and seed provenance. In this regard, Merou et al (2011) also found that the seed coat of Albizia julibrissin became permeable when seeds were immersed in sulfuric acid for 2 hours, which increased germination from 33% to 99%. Our results are consistent with those obtained in other studies of Fabaceae species in which acid scarification made the seed coat water-permeable, thus allowing seeds to imbibe and germination (Orozco-Almanza et al, 2003;Hu et al, 2009;Babashpour et al, 2011;Merou et al, 2011).…”

The results of research on seeds of Acacia auriculiformis (Olatunji et al, 2012) revealed that scarification with concentrated sulfuric acid for 5 and 10 minutes brought about the highest germination percentages (more than 92%) compared to that of the control (42%).…”

Effects of dormancy-breaking methods on germination of the water-impermeable seeds of Gleditsia caspica (Fabaceae) and seedling growth

et al. 2019

Various treatments can be used to break physical dormancy (PY, i.e. water-impermeable seed coat) of legume species, but the effects of these treatments on seedling growth are of great importance in the success of afforestation projects. Our aims were to determine the effects of 20 PY-breaking treatments on (1) germination of Gleditsia caspica (Caspian locust) seeds and (2) seedling growth. Five germination and nine seedling growth and morphological traits were studied. Immersion in concentrated sulfuric acid (98%) for 60 minutes was optimal for all germination traits and for all seedling traits except root length. After seed coat removal or treatment with sulfuric acid (for 45 to 120 minutes), 99–100% of the seeds germinated, but seedling growth traits after 5 months were significantly lower in the former than in the latter treatment. Other treatments (e.g., different periods of exposure to cold water, boiling water, and KNO3) did not significantly increase germination or improve seedling growth. Thus, despite incurring adverse environmental impacts, sulfuric acid treatments have the best potential to break seed dormancy and produce high-quality seedlings (in terms of shoot length, root and shoot mass, root area, leaf number and area and collar diameter) of Caspian locust.

“…This result demonstrated that above mentioned treatment had the destructive effect on embryo. It is notified that increasing in doses of sulfuric acid caused germination improvement and suggested chemical scarification in concentrated H 2 SO 4 for 2 hours [16]. In this research thiourea did not have a positive effect on germination improvement of C. persica.…”

The purpose of this study was to investigate the effects of different treatments on seed germination in the desert plant speciesCalotropis persica(Gand.). This species is known to have long time for seed germination considering arid region condition and short time of access moist. An experiment was performed with 13 treatments and 4 replications in a completely randomized design. Treatments included KNO3with concentrations of 0.1, 0.2, and 0.3 percent, immersion in hot water for five min, acetylsalicylic acid 100, 200, and 300 mg L−1, ethereal sulfuric acid (60%) for 5 and 10 min, thiourea with concentrations of 0.1% and 0.3%, and prechilling for 10 days. Tap water was used as the control. Our findings indicate that KNO30.1% and 100 mg L−1acetylsalicylic acid were the most effective treatments for improvement of seed germination properties in this species. In a comparison of the two mentioned treatment, KNO30.1% treatments is the best.
