“…The highest germination rate was recorded in the seeds primed with -0.8 MPa established with PEG and stored at 16°C. Priming caused the acceleration of RNA and protein synthesis and improved the activity of free radical scavenging enzymes such as superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) [Bilińska et al 2022]. Rouse and Sherrod [1996] found the MDG value between 9 and Lee et al [2010] stated that the differences in the effect of SA on seed germination depends on plant genotype and experimental conditions.…”

Rough lemon (Citrus jambhiri Lush.) – RL, is used as a rootstock for citrus plants in saline conditions. NaCl causes an osmotic stress on plants mainly preventing the water uptake by the roots and thus reducing the plant growth. The objective of this study was to determine the effects of salicylic acid (SA) on germination of seeds and the growth and development of seedlings of RL rootstock under salt stress. For seed germination, a study was conducted in a completely randomized design in a 4 × 4 factorial scheme (SA at 0.00, 0.25, 0.50, or 1.00 mM and NaCl at 0, 50, 100, or 200 mM) with 4 repetitions, totaling 64 plots, of 25 seeds per plot. RL seeds were incubated in SA solutions for 24 h. Then, they were treated with NaCl-containing water in Petri dishes and incubated in the growth chamber at 25°C. For greenhouse experiment, a study was conducted in a randomized complete block in a 4 × 4 factorial scheme (SA at 0.0, 0.5, 1.0, or 2.0 mM and NaCl at 0, 50, 100, or 150 mM) with 3 repetitions, totaling 48 plots, of 2 plants per plot. Some morphological and physiological characteristics were determined. While germination time was extended, germination ratio and radicle extension were decreased in seeds under salt stress compared to control. Moreover, in these conditions the leaf membrane permeability and leaf falling were increased. In turn, plant height, diameter, root and shoot dry weight, leaf relative water content, and leaf chlorophyll were decreased in seedlings. Salt stress had negatively affected seed germination from 97.5% in control to 23.5% in 200 mM NaCl. However, SA treatments significantly decreased plant height to 67.8 cm in 2.0 mM compared to 80.1 cm in control in RL rootstock.

Dynamics of the Ocimum basilicum L. Germination under Seed Priming Assessed by an Updated BBCH Scale

et al. 2022

Germination of the medicinal and aromatic plant basil raises interesting questions due to its no seed periodicity and dormancy demand, and the seed priming could help to assure the permanent needs for this herb. The study aimed to provide an adapted BBCH (Biologische Bundesanstalt Bundessortenamt and CHemical industry) scale for the germination secondary stages of sweet basil Ocimum basilicum L. (var. MVSt). A standardized germination test was performed with hydropriming, electric field, and magnetic field as priming methods to assess the changes in the secondary stages of germination. The time range for each basil secondary stage was recorded and added to the adapted BBCH, to highlight the daily secondary stage changes. All the seed priming methods increased the germination capacity with 2–3% compared with the control, with the highest value for electropriming. The seed priming methods studied improved the germination and changed the pattern of secondary stages in the BBCH scale. The germination energy was set to more than 90% in all primed seeds, with a maximum of 91.75% in the magnetic field. The time needed for 50% germination of seeds was set to 6.5 days and 90% germinated seeds were recorded after 11.7 days. The 09a BBCH lasted for 9 days in control and hydropriming, 10 days in electric field conditions and 7 days for magnetoprimed seeds.
