Seed germination is the initial step of plant development. Seed priming with salt promotes seed germination in tomato (Solanum lycopersicum L.); however, the molecular and physiological mechanisms underlying the enhancement of seed germination by priming remain to be elucidated. In this study, we examined the following in seeds both during and after priming treatment: the endogenous abscisic ac...

One of the methods for achieving more yields is to use seed priming technique correctly. When it comes to using seed priming, practically important issues should be taken into account including interval between priming to planting and conditions for storage of primed seeds. Thus, it is very crucial to be informed of duration and temperature for storage of primed seeds. This research seeks to co...

to better understand seed priming that improve seed germination and seedling uniformity, we examined the physiological role of osmopriming in germination of bread wheat (triticum aestivum l.) seed embryos by a proteomic approach. for this purpose, we used two systems. the first system consisted of osmo-primed seeds by peg 6000 at -0.8 mpa at 15?c for 24 hours, followed by air drying at 15?c, an...

This study aimed to evaluate the effects of priming on seed germination under salt stress and gene expression in seeds and seedlings of P. angulata L. After priming for 10 days, seed germination was tested in plastic trays containing 15 ml of water (0 dS m-1 - control) or 15 ml of NaCl solution (2, 4, 6, 8, 10, 12, 14 and 16 dS m-1). Fresh and dry weight of shoots and roots of seedlings were ev...

Lettuce (Lactuca sativa L. cv Minetto) seeds were primed in aerated solutions of 1% K(3)PO(4) or water at 15 degrees C in the dark for various periods of time to determine the manner by which seed priming bypasses thermodormancy. Seeds which were not primed did not germinate at 35 degrees C, whereas those which were primed for 20 h in 1% K(3)PO(4) or distilled H(2)O had up to 86% germination. T...

Recent studies have introduced seed priming with H2O2 as an effective technique to alleviate abiotic stresses in plants. In the current study, accomplished at Faculty of Sciences, Shahrekord University, seeds of medicinal plant Artemisia aucheri were primed with H2O2 (0, 10, 50, 90 and 140 µM) and grown under salt stress (0 and 150 mM NaCl) for one month. Results showed a decrease in H2O2 and m...

Generally, primed seeds produce larger and heavier plants than non-primed seeds. This may be simply due to rapid emergence and extension of leaf growth, or the influence of other physiological processes. The effect of seed pretreatment with salicylic acid (SA) on some physiological and photosynthetic characteristics of the safflower seedlings, cv. Goldasht, was examined under field condition. T...

the effects of bio-priming with different isolates of biological agent of trichoderma spp. and pseudomonas fluorescens on morphological and physiological characteristics of a bean cultivar (yaas) as well as their effects on controlling of rhizoctonia solani were investigated in two separate experiments. in the first experiment, different isolates of trichoderma including trichoderma harzianum b...
