The experiment was conducted at the research field of Regional Agricultural Research Station, Jessore during two consecutive rabi seasons of 2008-2009 and 2009-2010 to find out the effect of hydropriming on the performance of maize seeds under variable soil moisture regimes. The treatments of the experiment were two priming methods viz., i) Hydropriming, ii) Non-priming and four moisture regimes viz., i) Wet condition, ii) Field capacity, iii) 75% of field capacity, and iv) 50% of field capacity. Results showed that yield and yield contributing characters (plant population/m 2 , number of cobs/m 2 , length of cob, diameter of cob, 100-grain weight) were influenced significantly by hydropriming. Yield and yield contributing characters were highest when hydroprimed seeds were sown at field capacity whereas it was the lowest at 75% of field capacity from non-primed seeds. Days to tasseling, days to silking, and days to maturity were reduced when hydroprimed seeds were sown at field capacity. At 50% of field capacity, no germination was occurred.

-The objective of this work was to assess the regulatory effects of auxin-priming on gas exchange and hormonal homeostasis in spring wheat subjected to saline conditions. Seeds of and Inqlab-91 (salt-tolerant) cultivars were subjected to 11 priming treatments (three hormones x three concentrations + two controls) and evaluated under saline (15 dS m -1 ) and nonsaline (2.84 dS m -1 ) conditions. The priming treatments consisted of: 5. 71, 8.56, and 11.42 × 10 -4 mol L -1 indoleacetic acid; 4.92, 7.38, and 9.84 × 10 -4 mol L -1 indolebutyric acid; 4.89, 7.34, and 9.79 × 10 -4 mol L -1 tryptophan; and a control with hydroprimed seeds. A negative control with nonprimed seeds was also evaluated. All priming agents diminished the effects of salinity on endogenous abscisic acid concentration in the salt-intolerant cultivar. Grain yield was positively correlated with net CO 2 assimilation rate and endogenous indoleacetic acid concentration, and it was negatively correlated with abscisic acid and free polyamine concentrations. In general, the priming treatment with tryptophan at 4.89 × 10 -4 mol L -1 was the most effective in minimizing yield losses and reductions in net CO 2 assimilation rate, under salt stress conditions. Hormonal homeostasis increases net CO 2 assimilation rate and confers tolerance to salinity on spring wheat.Index terms: Triticum aestivum, hormonal balance, plant growth regulators, salinity, seed priming, stomatal regulation. Tolerância ao sal e regulação de trocas gasosas e da homeostase hormonal pelo condicionamento osmótico com auxinas em trigoResumo -O objetivo deste trabalho foi avaliar os efeitos regulatórios do condicionamento osmótico com auxinas sobre as trocas gasosas e a homeostase hormonal em trigo de primavera, submetido a condições salinas. Sementes das cultivares MH-97 (intolerante ao sal) e Inqlab-91 (tolerante ao sal) foram submetidas a 11 tratamentos de condicionamento osmótico (três hormônios x três concentrações + dois controles) e avaliadas sob condições salinas (15 dS m ; e sementes condicionadas em água (controle). Um tratamento com sementes não condicionadas também foi avaliado. Os agentes condicionadores diminuíram os efeitos de salinidade sobre a concentração de ácido abcísico endógeno, na cultivar intolerante ao sal. A produtividade de grãos correlacionou-se positivamente à taxa de assimilação líquida de CO 2 e à concentração de ácido indolacético; e negativamente ao ácido abcísico e às concentrações de poliaminas livres. De forma geral, o tratamento com triptofano a 4,89 × 10 -4 mol L -1 foi o mais efetivo em amenizar perdas produtivas e reduções na assimilação líquida de CO 2 , sob condições de estresse salino. A homeostase hormonal aumentou a taxa de assimilação líquida de CO 2 e conferiu tolerância à salinidade ao trigo de primavera.Termos para indexação: Triticum aestivum, balanço hormonal, reguladores de crescimento, salinidade, condicionamento de sementes, regulação estomatal.

A couple of experiments were carried out to investigate the effects of osmopriming and hydropriming treatments on the germination indexes and seed vigor of Tall fescue (Festuca arundinacea). In the first experiment, fulfilled based on randomized complete block designed with four replicates, the effect of polyethyleneglycol 6000 solution with five osmotic potentials (-8, -10, -12, -14 and -16 bar), two temperatures (15 and 25 o C) and four time intervals (12, 24, 36 and 48 hours) was analized. The second experiment was fulfilled by using distilled water at two temperatures (15 and 25 o C) and four time intervals (12, 24, 36 and 48 hours) with four replicates on the above mentioned data. Then, based on the maximum germination rate and vigor indexes, the optimal treatment composition was determined for osmopriming and hydropriming solutions in regard to the osmotic potential, temperature and priming duration. In osmopriming experiment, treatment composition of 12 hours at 15 o C and -8 bar had the most significant effect on the percent and speed of germination, length of radicle, coleoptile and seedling, as well as vigor indexes in Tall fescue. For hydropriming, the effect analyzed in the same condition as osmopriming, was observed in the majority of evaluated traits; treatment composition of 12 hours prime and 15 o C had the maximum numerical value in comparison to control and other treatments. Finally, it is inferred that favorable effects of osmoand hydropriming at 15 o C temperature are more significant in comparison with the control group (none prime seeds).
