“…The highest Germination (%) and lowest MGT were obtained for an interaction of 70 % H 2 SO 4 and 60 minutes. These results are in agreement with previous studies conducted by Kher and Nataraj (2015) and Purohit et al (2015). These results indicated that H 2 SO 4 can speed up the germination rate because MGT is decreased.…”

Least snout bean (Rynchosia minima L.) is considered a promising rangeland legume fodder for marginal land in Sudan, but its seeds are associated with high dormancy (%). This study was carried out at the Laboratory of the Plant physiology, Department of Botany and Agricultural Biotechnology, Faculty of Agriculture, University of Khartoum to investigate the effect of sulfuric acid (H2SO4) on breaking seeds dormancy of least snout bean. The seeds were soaked in 0, 50, 70, and 100% H2SO4 concentrations for 30, 45, 60, 90 and 120 minutes. The seeds were germinated in petri dishes and incubated at room temperature for 10 days. The H2SO4 concentration and soaking period significantly (P < 0.01) increased seeds germination (%) and decreased mean germination time (MGT). The germination percentage was increased while MGT was decreased by increasing soaking period up to 60 min. The highest germination (%) and lowest MGT were obtained by soaking the seeds in 70 % H2SO4 for 60 minutes. The result would be useful for large-scale establishment of least snout bean in natural rangelands.

“…In general, proper treatment with sulfuric acid has been demonstrated to open the plugged natural openings of seed coat, thus increasing the water absorption and gas exchange between placenta and its surrounding atmosphere. This, in turn, improves germination of seeds with PY (Li et al 1999;Rahnama-Ghahfarokhi and Tavakkol-Afshari, 2007;Baskin and Baskin, 2014;Purohit et al, 2015).…”

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.

“…From the results it was inferred that the physiological dormancy in M. nudicaulis seeds might be associated with seed coat therefore, to analyses the seed germination percentage after removal of the seed coat, the chemical scari cation of the seeds was taken in account. In chemical scari cation the sulphuric acid treatment has been widely used and studied to break physiological dormancy (Aliero 2004;Emongor et al 2004;Zida et al 2005;Purohit et al 2015). For M. nudicaulis the highest 38% germination was found after the acid pulse treatment.…”

In rapid climate change how C3-C4 plants will respond this is the question of study. Here, we present Mollugo nudicaulis Lam., a C3-C4 intermediate species known for C2 type photosynthesis as a model plant in the tropics. Therefore, to know the functionality and habit of M. nudicaulis in ambient climate, we analyzed the leaf anatomy quantitatively, recorded the local dispersion variance pattern of species, seed production potential (seed output per plant) and seed germination pattern. Natural and man-altered sites were explored to see the distribution of the plant. Seed output per plant was calculated. Cross-sections of mature leaves were observed. We compared ex vivo and in vitro seed germination profile by applying of primary dormancy breaking methods including –imbibition, scarification, and cold stratification to different time regime. M. nudicaulis follows the clump distribution in natural area due to hydrochory dispersion of seeds. In nature plant thrives in high organic rich sites. In ex situ germination, the acid scarification (physical change) and the cold stratification (physiological change) showed significant enhancement in germination after breaking of dormancy. The leaf anatomy showed variations in the number and the area of leaf mesophyll cells and the thickness of leaf as per fluctuation in average temperature, pressure, and humidity in a year. More palisade cells found in the leaves cross-section when the year recorded for average high temperature and more frequent rainfall. We found a correlation between the mesophyll cells in leaves and pre-monsoonal season variability for C3-C4 intermediate plant. The study adds supportive results in climate change impact on plant physiology and adaptation.
