“…Chilling stress during seed germination and seedling development limit the rate of germination and growth. The previous research showed that seed soaking with Put can improve chilling tolerance of maize seeds (Cao et al 2008). In present research, seed germination and seedling length, as well as dry weight of different chilling-response tobacco varieties were improved by the Put treatments under chilling condition.…”

“…It means that not only their synthesis, but also their degradation catalyzed by polyamine oxidases may determine their role in stress signalling processes. Furthermore, chilling tolerance of maize can be improved by soaking of seed in Put underlining the specific role of polyamines in stress responses (Cao et al 2008). …”

The application of naturally occurring biologically active compounds could be an effective method to improve crop productivity under changing environmental conditions. In the present work the effects of priming maize seed with salicylic acid were tested on the grain yield under field conditions, and on the salicylic acid and polyamine metabolism under controlled environmental conditions. The field data suggested that the beneficial effects of pretreating maize seed with salicylic acid were mainly detectable in the yield in the case of early sowing dates. When young maize seedlings were exposed to low temperature stress, priming the seed with salicylic acid only modified the salicylic acid levels in the seed but not in the roots or leaves. The data suggested that salicylic acid was taken up by the seed and was then converted to bound forms. In contrast to salicylic acid, 5 days after sowing there was a substantial increase in the free form of ortho-hydroxy cinnamic acid in the seed, roots and leaves. Priming with salicylic acid also led to an increase in the putrescine content and a slight decrease in spermidine in the seed. The levels of putrescine, spermidine and spermine also increased in the roots of plants treated with salicylic acid under normal growth conditions. The results suggest that polyamines may also contribute to the stress tolerance of plants primed with salicylic acid.

“…As putrescine accumulation reduced the chilling injury in tomato (Solanum lycopersicum L.) (Kim et al, 2002), chickpea (Cicer arietinum L.) (Nayyar, 2005) and maize (Cao et al, 2008) under chilling stress. Many studies demonstrated that genetic modification of the polyamine biosynthetic pathway is a useful tool to recognize the function of polyamines in plant responses to abiotic stresses in both crops and model plants (Igarashi and Kashiwagi, 2000;Childs et al, 2003;Kusano et al, 2008).…”

“…Xu et al (2011) showed that the amount of seedling leaf relative water content (RWC) improved under chilling stress via seed priming with putrescine probably by osmotic adjustment or might alter in cell wall stretchiness. Cao et al (2008) reported that seed soaking with putrescine improves chilling tolerance of maize seeds.…”

Chilling stress is a major limiting factor for rice production in many parts of the world. The study was carried out in the Seed Research Laboratory of the Department of Crop Science, Ferdowsi University of Mashhad in summer 2011. Rice (cv. Khazar) seeds were soaked in 50, 150 and 300 mg L -1 spermidine aerated solutions for 48 h and then dried back to the original moisture content and were sown in three temperatures (28°C as normal, 12 and 8°C as chilling stress). Chilling stress (8°C) reduced the root (39%) and shoot (52%) growth in untreated seeds, while the reduction of 11% root growth and 20% shoot growth was observed when the seeds were primed with 300 mg L -1 spermidine solution. The electrolyte leakage (EL) of the seedling leaves significantly increased in low temperatures as it was 67% in 8°C in compared with normal condition. Chilling stress significantly increased superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) activity in rice seedlings leaves though this increase was not significant for glutathione reductase (GR). Seed priming with spermidine had a positive effect on seedlings leaves antioxidant activity in every temperature conditions. As in 8°C, the sharp increase (73%) in SOD activity was occurred at 300 mg L -1 spermidine solution and it was 23 and 46% for CAT and APX, respectively. In general, seed priming with spermidine alleviated the chilling effect, probably as a result of activating antioxidants production processes and membrane stabilizing in cellular structures.
