Effect of seed priming with kinetin on germination indices and proline activity of Silybum marianum L. under drought stress conditions

Abstract

For investigation of the effect of seed priming by kinetin on germination indices and proline activity of Silybum marianum L. under drought stress, factorial experiment based on completely randomized design with two factor includingdifferent concentrations of kinetin (0, 10 and 20 ppm) and different levels of drought stress including 0, -6 and -12 barat three replicates was carried out. According to the results, drought stress and kinetin individualy cause to decreases of germination percentage, germination rate, seedling length, seed vigor and seedling dry weight but uses of kinetin in drought stress condition improvment of them. Also, drought stress cause to increases of proline content and catalase activity. Therefore, seed priming with 10 ppm kinetin at drought stress was improved the germination indices of Silybum marianum L.DOI: http://dx.doi.org/10.3126/ijls.v9i1.11919 International Journal of Life Sciences Vol.9(1) 2015 6-11

Application of solid matrix priming to ameliorate salinity stress in mung bean (Vigna radiata)

“…Our interest in selection of suitable elicitors in SMP system in mung bean seeds came from several research workers (Akbari et al, 2010, Muzaffar et al, 2012, Zavariyan et al, 2015, Gahtyari et al, 2017, Mahdavi and Rahimi 2013. The priming agents were selected under five categories viz., hormonal priming (Kinetin, GA 3 , NAA and ABA), phenyl propanoids (gallic acid, catechol, and chitosan), Amine/amino acid (putrescine and proline), components related with calcium ion as a mediator of cell signaling (CaCl 2 as exogenous source of calcium ion, LaCl 3 as blocker and EGTA as chelator of calcium), and NO generating agent (SNP).…”
