Experiment was conducted in the Seed Testing Laboratory during 2013 and 2014 at RARS, UAS Campus, Vijayapur, Karnataka State. The seeds were primed by soaking in different leaf extracts and chemical solution for one hour and then decanted the extracts and seeds were air dried under the shade to bring back to their original moisture content and used for seed quality studies. Seed germination was significantly influenced by age of the seeds and its interaction with botanicals and chemicals. Among the treatments, botanicals viz., Prosopis leaf extracts @ 2per cent recorded higher seed germination followed by Pongamia leaf extract @ 2per cent. Whereas, in chemicals higher germination was seen in KNO3@ 0.5 per cent but at par with CaCl2 .2H2O @ 2 per cent. Lower seed germination was obtained with water soaked and control. The present investigation indicate that, seed priming with 2.0 per cent Prosopis leaf extract for one hours soaking enhanced the seed and seedling quality characters, and hence it could be adopted as a pre-sowing seed priming treatment in pigeon pea.

Sowing Seed

Legumes being a major source of protein have a wide range of economic importance. But the major constraints in growing legumes are poor germination, seedling emergence, non uniform stand establishment and crop mortality leading to lower pulse productivity. Thus, pre-sowing seed treatments are critical parameters which attribute to efficient plant growth and high yield. Uniform seed germination, seedling growth and uniform establishment are the critical stages during the growth of crops. Seed priming is a very promising presowing treatment employed to improve seed germination, better crop establishment, enhance the seed quality and induces tolerance against biotic and abiotic stresses in plants thereby providing a balanced healthy diet to the citizens. Priming is a cost effective and feasible strategy involving controlled hydration of seeds followed by drying to stimulate the pre-germinative metabolic activities to occur promoting rapid germination of seedlings, break dormancy and enhance crop yield. Enzymatic, metabolic and biochemical processes of the primed seeds attributes to rapid and uniform seedling emergence. Seed priming methods comprises of conventional methods including hydro priming, osmopriming, biopriming, chemical priming and the advanced methods including nano priming and priming with physical agents. In this review paper, the underlying physiological, biochemical and molecular aspects of priming in pulses were discussed.

Allelopathy, an important mechanism in invasive species stems from the lack of coevolved tolerance of indigenous species to novel chemicals released by the invader species. These chemicals are key to successful invasive of species of natural plant communities and ecosystems. This study analyzed the allelopathic effects of the invasive plant, Parthenium hysterophorous on the growth of kidney beans (Phaseolus vulgaris). One hundred and fifty viable kidney bean seeds were washed in distilled water, and transferred in triplicates to pots with wet sterile sand. Ten grams of freshly collected Parthenium leaves and roots were weighed, grounded separately using a mortar and a pestle, mixed with 100 ml of distilled water in a beaker and left for 24 hours in a dark at a room temperature (250C). The aqueous extract filtrates were used in experimental treatments. While untreated (control) seeds germinated on day 4 seeds treated with leaf extract germinated on day 14 and day 9 for the root extract. Leaf extract inhibited germination and sprouting of new leaves more effectively than root extract. Leaves in control seeds appeared on day 1 after germination. In treated seeds, leaves appeared on the 4th day then stagnated until day 15 when more leaves sprouted. Root extract significantly depressed seed germination. The number of new leaves increased significantly in control seedlings compared to the treated ones. Combined root and leaf extracts highly significantly inhibited of seed germination and the number of new leaves. Additionally, combined treatment with root and leaf extracts significantly inhibited shoot growth, and the increase in leaf length and width. A comparison of the effectiveness of the root and leaf extracts showed that leaf extract was more effective in inhibiting shoot growth and leaf width than the root extract.

Four Levels

Field experiments were conducted with four levels of seed priming including control and two varieties of pigeon pea at ICAR-Indian Institute of Seed Science, Mau during three consecutive years (2011-12 to 2013-14). One-year-old seeds of pigeon pea varieties (Bahar and Malviya-13) were primed with growth regulator (100 ppm GA3), in-organic salt (0.2% KNO3) and tap water (sanitized) separately for 06 hrs. and sown in field under RBD with 03 replications. Observations were recorded on seed quality parameters, biochemical attributes including nitrate assimilatory enzymes and activities of anti-oxidant enzymes during seedling stage. Seed quality parameters including germination, seedling growth and vigor indices were significantly enhanced through seed priming with GA3 followed by KNO3 and tap water over unprimed control. Biochemical attributes viz; chlorophyll a andb contents, were more influenced with GA3 priming followed by KNO3 and tap water whereas the proline accumulation was reduced with priming treatments and maximum reduction was noted with GA3 followed by KNO3 and tap water. Enhancement in nitrate assimilatory enzymes including nitrate and nitrite reductase activities was more with KNO3 priming followed by GA3 and tap water. Anti-oxidant enzymes activities including Catalase, Peroxidase and Super Oxide Dismutase were also increased significantly by KNO3 priming followed by GA3 and tap water over unprimed control.

Fire is a natural process that opens Typha latifolia L. stands by removing aboveground biomass, but little is known about how ash resulting from marsh burning affects Typha seed germination. We measured the response of T. latifolia seed to simulated pre- and post-fire effects under laboratory conditions and tested seed collected in spring for the effect of ash on seed germination and seedling morphology. Seeds were soaked for 7 days in aqueous solutions of leaf extracts, ash additions, and various pH solutions in light and dark treatments at 25 °C in vitro. In light, seed germination did not vary significantly (P < 0.01, Tukey's honestly significant difference test) among solution treatments. In darkness, seed germination was inhibited mostly by green leaf extract and yielded only 15% germination. Addition of ash to green leaf extract resulted in a germination of 40%. Solutions with pH of 4.0, 7.0, and 12.0 had no signifcant effect on germination or total plant lengths, regardless of the light treatment. Root to total plant lengths were decreased by dark treatments but not by pH. Root development was strongly inhibited by green leaf extract even with ash. Shoot growth continued with no apparent root development only in these two solutions. Three implications for marsh management of T. latifolia are proposed.

Seed Ageing

Most of the medicinal plants have seed dormancy or poor seed germination. This is due to their natural compounds or their morphological structure. Existence of such mechanisms makes the seeds able to endure harsh environments, stressful conditions or natural ageing. Different seed enhancement treatments were proposed in order to improve seed germination. In this study, it was examined Silybum marianum seed longevity (0, 48 and 72 hour of ageing) and the response to seed priming when using different concentrations of cytokinin (50, 200, 350 and 500 ppm) and different duration of treatment (8, 12 and 24 hour). Results revealed that ageing could be successfully alleviated using seed priming. Seed ageing significantly affected seed germination and vigour. Application of cytokinin considerably improved seed vigour in aged and non aged seeds. The most effective seed priming treatment was with 500 ppm cytokine, with the duration of 24 hours. In conclusion, it can be recommend the used of plant growth regulators like cytokine, as a good priming agent, to recover losses of seed quality and improve germination characteristics.
