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.

Background: Seed priming technique involves soaking of seeds in priming agent to a point where germination related metabolic activities occur in the seeds followed by drying of imbibed seeds to original moisture to prevent the radical protrusion and facilitate storage of primed seed. Draining of priming agent and drying of large quantity of primed seeds is a laborious and time consuming process. The current study was aimed to standardize automation of seed priming process by utilizing house-hold top loading washing machine. Methods: The top loading washing machine referred to as Seed Priming Cabinet, contained a priming drum with provision for draining water. On completion of the soaking period, the ‘SPIN’ button was pressed by setting the duration of spin drying (1, 2, 3, 4 and 5 min.). Then the seeds were removed from the drum of priming cabinet and subjected to shade drying so as to reach the original moisture content and evaluated for seed quality parameters. Result: The blackgram seed subjected to conventional hydropriming was compared with automatic seed priming for 1, 2, 3, 4 and 5 min. and observed that hydropriming and spin drying for 3 min. was found to be optimum and the per cent increase in germination recorded over control was 18.0 per cent thus suggesting that automation of seed priming technology can be recommended for enhanced seed vigour and crop productivity of blackgram.

Field experiments were conducted to determine the effects of herbivory, seed priming, and tillage practices on the growth response of Pisum sativum L. A factorial treatment design incorporated two levels of tillage treatment (moldboard and chisel plow), three levels of seed priming [Captan, PEG (polyethylene glycol) 8000, and Captan+PEG 8000], and four levels of herbivory by Sitona lineatus (L.) (caged controls, uncaged controls, 1 weevil/plant, and 8 weevils/plant). Pisum sativum stands at approximately 75% emergence were infested for 1 wk. Sitona lineatus infestations resulted in defoliation of approximately 5, 25, and 55% for the control, low, and high weevil densities, respectively. Conservation tillage led to increased surface residue but did not affect soil moisture, temperature, or compensatory growth response of P. sativum. Seed priming treatments, incorporating PEG, led to an undercompensatory growth response of P. sativum, as did high levels of S. lineatus defoliation. Improved seed priming methods that promote vigorous seedling growth may help minimize the impacts of S. lineatus and suboptimal soil conditions on P. sativum.

Sorghum is being produced primarily as a food grain throughout the world. It is one of the major traditional food crops in Ethiopia. However, the productivity of the crop is very low and poor seed quality is one of the major determinants. An experiment study was conducted in laboratory and glasshouse to evaluate the effect of seed priming on seed quality parameters of three sorghum varieties:(Muyra-I, Muyra-II and Fendisha) with different storage of one year and two years using different priming agents with different soaking time for each priming agent (1.0mM KNO3, 1mM NaCl and distilled water for 72, 48 and 12 hours respectively) in 2012 at Haramaya University Seed laboratory. Completely randomized design in 2 x 3 x 4 factorial arrangement with three replications was used to carry out the germination and vigor tests. The priming concentrations and durations were based on previous work, which was effective in hydro and osmo-conditioning of sorghum seed. In the experiment, seed priming increased germination percentage (GP), Mean Germination Time (MGT) and improved seedling shoot (SSL) and root length (SRL), seedling dry weight (SDW) and seedling vigor indices in all varieties of both storage durations compared to their respective control. Priming with NaCl and KNO3 showed positive response followed by hydropriming for all varieties of different storage duration. When treated with sodium chloride, almost all the varieties of each storage year demonstrated an increase in germination and the degree of increment was higher for Muyra-I(__) and Fendisha (___), the lowest being for Muyra-II which was significantly lower for both storage year. In case of mean germination time Fendisha exhibited better with hydropriming for older seeds (___) and with KNO3 for newer seeds(___) while Muyra-II and Muyra-I showed better with KNO3 (____) for older seeds and with hydropriming for newer seeds. Responses of varieties for the remaining parameters were intermediate. Therefore, sorghum seed priming with osmo-media and water can compensate storage deterioration of sorghum seeds in addition to significantly improving the seed germination and vigor quality parameters

Solanum Nigrum L

The seeds must be viable and non-dormant for the efficient cultivation of the species of medicinal plants. The seeds of Solanum nigrum possess primary dormancy, which restricts germination. Hence, a laboratory experiment was conducted during 2019 in the Department of Seed Science and Technology, Agricultural College and Research Institute, Madurai, Tamil Nadu. The S. nigrum seeds were primed by soaking in different chemicals viz.,GA3 100ppm, Thiourea1%, KNO3 0.5%, Succinic acid 100 ppm, Ascorbic acid 100 ppm, hydro and dry control with soaking durations of 12h and seeds were dried under shade to bring back to their original moisture content and used for assessing the seed quality studies. The results revealed that among the different priming treatments Thiourea 1% recorded higher seed quality parameters viz, speed of germination (5.6), germination (88 %), seedling length (5.92 cm) and vigour index (520) and the enzyme activity of dehydrogenase (0.072 OD value) and lower values of electrical conductivity( 0.027 dsm-1),  amino acids (0.119 ?gg-1 ) and sugars ( 0.175 ?gg-1 ). Hence it could be recommended as pre-sowingg seed priming treatment in S. nigrum.
