“…For dry mass of whole seedlings, length of the largest root, and shoot length, exponential increases occurred up to 55.00, 37.63, and 44.44 min, respectively (Figure 2). The effects of seed immersion times in sulfuric acid on seedling development and initial growth have been reported for several species (Silva et al, 2018;Nourmohammadi et al, 2019). Nevertheless, the results found in literature are generally contrasting and inconclusive.…”

To increase genetic variability, sweet potato needs to be sexually propagated in breeding programs. However, its seeds have a hard and thick integument, requiring some dormancy breaking method. Chemical treatment of seeds allows greater efficiency of the relationship between seeds obtained in crosses and those that germinate, providing genotypes to be tested for their potential, aiming at developing a new commercial cultivar. Thus, the objective of this study was to identify the effects of immersion times of seeds in sulfuric acid (98%) on the germination and initial growth of sweet potato seedlings. The seeds were immersed for five different times: 0 (control), 20, 40, 60, and 80 min. The experiment was carried out in a completely randomized design with ten repetitions consisting of 25 seeds each experimental plot. The germination percentage, germination speed index (GSI), dry mass of whole seedlings, and length of the largest root and shoot of the seedlings were evaluated. The germination percentage and GSI increased with immersion time until 53.30 min, with maximum estimated values of 85.39 and 25.10%, respectively. For the parameters dry mass of whole seedlings, length of the largest root, and shoot length, increases were observed up to 55.00, 37.63, and 44.44 min, respectively. In conclusion, the immersion of sweet potato seeds in sulfuric acid (98%) for 53 min is ideal for breaking dormancy and providing better conditions for the initial development of seedlings.

“…Therefore, in previous experiments with the related species C. varia, GA 3 , sulfuric acid, and HCl were tested. The best results were obtained using GA 3 , contrary to other Fabaceae species, where mechanical abrasion or sulfuric acid improves germination [19,20]. With this information, an experiment to compare different concentrations of GA 3 was set.…”

Coronilla viminalis Salisb. is a fodder leguminous plant from the Canary Islands and Northwestern Africa with adaptation to drought. Its conservation status is critical. Its low germination capacity and intense loss of viability of the seeds over time complicate its conservation, limiting its long-term maintenance in germplasm banks and hampering its potential use as a resilient fodder crop. Therefore, in this work, two alternative propagation methods have been addressed. The first was based on facilitating seed germination under aseptic conditions, supplementing the media with gibberellic acid (GA3). The latter consisted of creating a micropropagation method from nodal segments and testing different media and pretreatments with indole-3-acetic acid (IAA). The quantity and quality of the roots were assessed, and the plant acclimation rate was measured. The results showed that the optimum concentration of GA3 for germination, up to 98%, was 250 PPM. The experiments showed that using IAA in the micropropagation media is critical for in vitro rooting in this species. A hormonal pretreatment with IAA significantly improved the rooting efficiency compared to supplementing it into the culture media. One hundred percent of acclimated plants survived the process. These new protocols will help conserve the species and explore its possibilities as fodder crops.

“…On husk media, the development the emergence of the first folium compositum was seen on day 20 (12 leaves), the second compound leaf on day 30 (30 leaves), the third compound leaf on day 40, and the fourth compound leaf on day 50 (20 leaves) (Figure 3). Based on study about effect of dormancy-breaking methods on germination of Gleditsia capsica (Fabaceae), revealed that the largest number of leaves per seedlings was derived from seeds treated for different periods time with sulfuric acid for 60 and 120 minutes (14).…”

Senna alata (L.) Roxb., locally known as “Ketepeng China” from the family of Fabaceae, is a shrub or small tree that is used as an ornamental flowering shrub and for medicinal purposes in tropical and subtropical countries. Various parts of S. alata plant (leaves, flowers, roots, or stem) are used in traditional medicines to treat typhoid, diabetes, malaria, asthma, ringworms, scabies, and eczema. The present study was designed to investigate plant conservation by establishing an efficient seed germination method. The seeds of S. alata responded differently in growth to each location and medium. The best result-produced seedlings are grown in pots filled with sand, both at Bogor and Cibodas. The percentage of seed germination on sand was higher (around 96.7%) than on husk media (about 10%) for 10 planting days.
