Abstract :
Salinity of the limiting factors crop production in world. For interdict of effects harmful this salinity an test order to the effect of priming (hydro priming, salicylic acid and nano silver atomic) seed on the improve indices germination and seedling growth triticale (x triticosecale vittmack) under salt stress operating on four levels of salinity (0,6,10,14 dsm-1) and, salisylic acid 20 ppm and nano silver particles 10 ppm). This research in a factorial completely randomized design with three replications implement in the laboratory expertise Agricultural University- Varamin in year 2014- 2015. The results showed that high salinity stress reduce rate and percentage of germination in testes standard germination and cold test and accelerated aging test. Interactive effects of salinity and nano silver particles and Salicylic acid could also have a significant effect on the length seedling, length plumule, length root and rate of germination and rising tension in the plant (at 14 dsm-1), nano silver particles and Salicylic acid failed to prevent damage to the plant. most rate germination in treatment without salinity and pretreatment salicylic acid with mean 8.07 seed in day and least rate germination product in treatment salinity 14dsm-1 and un priming with mean 2.68 seed in day. most length seedling, length root, length plumule in treatment without salinity and pretreatment nano sillver mean order occur by 191 mm, 105mm, 85mm and least quantity factors mean order cause by mean 72mm, 34mm, 37 mm in treatment salinity 14dsm-1 and un priming. most rate appearance seedling accrue in treatment without salinity with mean 10/81% and least rate appearance seedling in salinity 14dsm-1 with mean 7/91 and in treatments priming most rate appearance seedling in treatment nano silver with mean 10/57 % and least that come in treatment un priming with mean 6/85.in treatments salinity most rate germination in cold test in treatment control with mean 65% and least that accrue in salinity 14dsm-1 with mean 43% .most percentage germination in treatment nano silver with mean 62% and least that accrue in treatment control with 37%. in treatments salinity most percentage germination in accelerated aging test in treatment control with mean 52% and least that in salinity 14dsm-1 with mean 30%.in accelerated aging test most percentage germination in treatment nano silver with mean 51% and least that accrue in treatment control with mean 29%.
