“…Similarly, Jowkar et al (2012) concluded that faster germination in primed seeds of milk thistle was due to enhanced activities of antioxidant enzymes and higher soluble protein levels in the seed. Other researchers have also declared the beneficial effects of priming for improvement of emergence potential and stand establishment of milk thistle seeds under abiotic stresses (Parmoon et al, 2013;Nasiri et al, 2014).…”

The present study elucidates the impact of different priming strategies on seed emergence and growth of milk thistle [Silybum marianum (L.) Gaertn.] and also evaluation of the efficacy of various extraction methods for optimal extraction of silymarin from milk thistle seeds. Seeds were primed with distilled water, Humic acid (2%), potassium chloride (2%) and moringa leaf extract (3%) for 24 h. Untreated seeds were used as control. Primed and non-primed seeds were sown in plastic pots. Seed priming treatments significantly improved the performance of milk thistle seeds as indicated by higher values of final emergence and lower values of mean emergence time and time taken to 50% emergence as compared to non-primed seeds. Silymarin was extracted from seeds of milk thistle by applying various techniques like Reflux, Soxhlet, maceration and microwave assisted extraction by using various solvents. Extraction with Soxhlet and microwave assisted techniques were proved better as compared to the others. The results indicated that in both spectrophotometric and HPLC quantification, silymarin contents were found maximum in extracts prepared with methanol by microwave assisted extraction technique followed by Soxhlet.

“…The highest GRI (26.82) was recorded in treatment P 2 (hydro priming 12 hrs) which was at par with that of P 14 (25.89). The probable reason for enhancement of GI and GRI of the hydro primed seed may be due to the completion of pregermination processes like synthesis and repair of nucleic acids (DNA and mRNA), proteins and repair of cell membrane, improved turgidity (Jowkar et al 2012) and stimulation of wide range of biochemical changes, enzymatic activations (Wattanakulpakin et al 2012). KNO 3 priming of Lycopersicon esculentum seeds depicted improved germination, emergence of seedlings and the initial growth of various plant species (Zhang et al 2012).…”

Seeds of China aster cv. Powderpuff were subjected to two conditioning techniques viz, hydroconditioning and halo-conditioning at different levels of concentrations and subjected time durations, constituting a total of 16 treatment combinations (P1 - P15) along with control (P0). Hydro-priming for 12 hrs and the halo-priming with 2 % KNO3 for 12 hrs significantly improved germination, mean germination time, germination index, germination rate index and growth attributes of China aster cv. Powderpuff. Hydropriming being simple economical and eco/subject friendly and safe is recommended for effective germination and growth of China aster cv. Powderpuff.

“…The higher uniform and germination percentage of primed seeds were due to the activation of a series of germination processes, including imbibitions and nucleic acid synthesis during seed priming processes (33). Also, the acceleration of germination in primed seeds can be attributed to the increasing rate of cell division in these seeds (34) and stimulation of the metabolic activities involved in the initial seed germination phase (35,36). On the other hand, temperature seems to play an important role in improving the germination process.…”

“…The beneficial effects of priming on the germination capacity and vigor of the seed was most probably due to stimulation of metabolic activities in the embryo i.e., synthesis of nucleic acids (DNA and mRNA), protein production, repair of cell membrane (7,14,35) and induction of biochemical changes such as breaking of dormancy, hydrolysis of inhibitors and enzymes activation (40). Numerous studies have been performed to exhibit the considerable effectiveness of hydro-priming on germination and seedling growth in many crop species, e.g., barley (41), chickpea (42), wheat (43) and sugar beet (12).…”

Seed priming improves seed performance in many crop species. In this study, the influence of hydrothermal priming on seed parameters of sugar beet is investigated in both laboratory and field conditions. In the laboratory, the treatments consist of a combination of cultivars (Arya and Shokoofa), hydro-priming at two temperatures (10 and 15 °C) for 6, 10, 14, 18, 22 hours. Germination traits and seedling growth were measured for determination of optimum hydro-thermal priming. Also, the protein pattern in the optimum hydro-thermal priming treatments and unprimed seeds were compared by electrophoresis. In the field experiment, the percentage and rate of emergence of primed and unprimed seeds were measured. Results showed that hydro-thermal priming had a positive effect on final germination percentage, mean germination time and uniformity of germination. Optimum hydro-thermal priming time and the temperature were 6 and 10 hours at 15 °C for Shokoofa and Arya cultivars respectively. Hydro-thermal priming increased the seed emergence percentage in the field by 15%. There was no significant difference in protein pattern between primed and unprimed seeds. In general, hydro-thermal priming not only increases sugar beet seed germination in the laboratory but also has a more positive effect on the emergence in the field condition.
