“…The highest survival percentage (91.00) was obtained from the T1M3 treatment, whereas the lowest survival percentage (67.00) was obtained in T0M4 treatment (Figure 4A). The result was similar to Ambica and Balakrishnan [32] in cluster beans. It could be because GA3 maintained a high water content in the cell, accelerated cell division and cell elongation, which increased seedling germination and overall growth, which may have contributed to higher seed vigour.…”

The most crucial factor in producing papaya seedlings successfully is seed germination. The purpose of this study was to investigate the influence of seed priming with growing media on seed germination and seedling growth of papaya from October to December 2022. The experimental treatments included three seed priming treatments: T0 = control (no seed priming treatments), T1 = GA3 (100 ppm), and T2 = KNO3 (1%), and four growing media, viz., M1 = soil + vermicompost (1:1), M2 = soil + cowdung (1:1), M3 = soil + cocopeat + vermicompost (1:1:1), and M4 = soil + cocopeat + cowdung (1:1:1). The treatments showed a significant effect on different parameters such as germination percentage, days to germination, survival percentage, chlorophyll content, seed vigor index, shoot, and root length. GA3 treated seedlings performed better than non-GA3-treated seedlings. Among the growing media, M3 showed the best for seed germination and other growth attributes compared to other growing media. In terms of interaction effects, T1M3 showed the highest performance for germination percentage (84.33%), survival percentage (91.0%), and chlorophyll content (44.26%). T1M3 also showed the highest seed vigor index, shoot and root growth, and plant biomass. As a result, the combination of GA3 and growing media containing soil + cocopeat + vermicompost was shown to be the most favorable for papaya seed germination and seedling growth.

“…This is most likely related to the superior seedling emergence in this treatment; seeds emerged faster, which would have facilitated a more rapid transition to autotrophic growth, photosynthesis, and hence more vigorous plants relative to untreated seeds. Priming has been shown to offer similar benefits in several vegetables (Batool et al, 2015;Behera, 2016) and crop species (Ambika & Balakrishnan, 2015).…”

Pepper (Capsicum annuum L.) is one of the most consumed horticultural products worldwide. However, pepper seeds have slow and asynchronous germination. Organic agriculture encourages using natural substances for the pre-germinative treatment of seeds. The objective of the present work was to evaluate the effect of priming sweet pepper seeds with bromelain crude extract (obtained from pineapple stem residues) on subsequent seedling emergence and growth. The effects of the proteolytic activity of the extract (0, 3.16, 6.25, 12.25, and 25.0 totalU), imbibition time (0, 3, 6, 9, 12, and 15 h), and imbibition temperature (15, 25, 35 and 45 ℃) on seedling emergence and growth were assessed. The significantly best emergence, based on a range of indicators (emergence percentage: E, time to 50% emergence: TE50, emergence index: EI, mean emergence rate: MER, mean emergence time: MET, and synchronization index: SI), was obtained when the seeds were treated for three h at 35°C with a 6.25 totalU bromelain crude extract. Seeds subjected to this treatment combination also yielded the most vigorous seedlings (number of true leaves, length and thickness of the stems, fresh mass, dry mass, leaf area) . In conclusion, pre-germinative treatment with bromelain crude extract of 6.25 totalU proteolytic activity for three h at 35°C improved seedling emergence and growth in sweet pepper seedlings relative to untreated seed. This result offers an organic priming alternative for seeds of sweet pepper.

“…According to previous research, it has been reported that in wheat plants Zn plays an effective role in the production of increased dry weight (Mahmood et al, 2019). While having comparison with results provided on seed priming effect on growth parameters of maize, it has been revealed that ZnSO4 seed priming treatment influenced positively shoot and root length of maize and pulses (Ambika and Balakrishnan, 2015). An increased root length of plants grown from seeds primed with ZnSO4 as compared to unprimed seeds could be the result of extensibility in the cell wall of the embryo (Mahmood et al, 2019).…”

“…Salinity increases the activity of antioxidant enzymes were all priming treatments. Ambika and Balakrishnan (2015) reported that seed priming treatment caused an increase in the activity of ROS scavenging enzymes to enhance plant strength and viability. Metabolic activities are expected to increase remarkably in seeds following their priming which may lead to the higher activity of ROS as secondary products of mitochondrial respiration.…”

Seed priming has proved to be an effective method in imparting stress tolerance to plants using natural and/or synthetic compounds to treat the seeds before germination. The present study was designed to investigate the physiological mechanism of seed priming with ZnSO4 (osmopriming) and distilled water (hydropriming) on sugar beet genotypes (‘Shokofa’, ‘Sina’, ‘Paya’, ‘Turbata’, and ‘Aria’) germination indices, seedling growth parameters, and biochemical properties under salinity stress (0, 2, 5, and 12 dS/m NaCl). A significant reduction in germination percentage (33.23%), germination rate (77.2%), chlorophyll a, b, and total contents (43.9, 31.9, and 39.9%, respectively) while, a significant increase in radical, plumule, and seedling length (57.1, 44.4, and 51.2%, respectively), seedling vigour index (48.9%), superoxide dismutase activity (61.3%), proline (54.0%) and sugar (56.3%) contents were achieved at 12 dS/m NaCl in compared to the control treatment. Seed hydropriming and osmopriming caused significant improvements in photosynthetic pigments, antioxidant enzyme activity, and proline content reflected in high germination percentage and rate as well as seedling vigour index and reduced mean germination time under salinity. ‘Paya’ and ‘Aria’ genotypes had a superiority according to the germination percentage and seedling vigour index, respectively. The hydropriming of ‘Paya’ genotype resulted in the highest germination percentage (95%) under high level of salinity (12 dS/m) which 11.84% increase compared to the control treatment. Hydropriming of ‘Sina’ seeds showed the highest chlorophyll a and total, and carotenoids under non-stress conditions (22.89, 31.65, and 2116.6 µg/g FW). Also, hydropriming by increases chlorophyll b content led to the modulation of the negative effects of high salinity stress (12 dS/m). In conclusion, different seed priming treatments in sugar beet seeds improved the salinity tolerance by physiological characteristics nonetheless hydropriming was the most effective treatment to get higher germination indices in ‘Paya’ and ‘Aria’ genotypes.
