“…Increases of ROS generation and resultant peroxidation of membrane lipids in chilled leaves are common to chillingsensitive species and cultivars (Omran, 1980;Prasad et al, 1994;Saruyama and Tanida, 1995). Accumulation of hydrogen peroxide in cv Suyo leaves during chilling (Fig.…”

The possible involvement of polyamines (PAs) in the chilling tolerance of cucumber (Cucumis sativus L. cv Jinchun No. 3 and cv Suyo) was investigated. Plants with the first expanded leaves were exposed to 3°C or 15°C in the dark for 24 h (chilling), and then transferred to 28°C/22°C under a 12-h photoperiod for another 24 h (rewarming). Chilling-tolerant cv Jinchun No. 3 showed a marked increase of free spermidine (Spd) in leaves, once during chilling and again during rewarming. Putrescine increased significantly during rewarming, but the increase of spermine was slight. Any of these PAs did not increase in chilling-sensitive cv Suyo during either period. PA-biosynthetic enzyme activities appear to mediate these differences between cultivars. Pretreatment of Spd to cv Suyo prevented chill-induced increases in the contents of hydrogen peroxide in leaves and activities of NADPH oxidases and NADPH-dependent superoxide generation in microsomes and alleviated chilling injury. Pretreatment of methylglyoxal-bis-(guanylhydrazone), a PA biosynthesis inhibitor, to chilled cv Jinchun No. 3 prevented Spd increase and enhanced microsomal NADPH oxidase activity and chilling injury. The results suggest that Spd plays important roles in chilling tolerance of cucumber, probably through prevention of chill-induced activation of NADPH oxidases in microsomes.

“…Lee and Lee (2000) indicated that higher APX activity in plant leaves under chilling stress is a more efficient scavenging system which may result in stronger protection against ROS during chilling. Similarly, Saruyama and Tanida (1995) demonstrated that increase in the activity of APX and CAT leads to chilling tolerance in rice cultivars.…”

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.

“…Chilling temperature increases superoxide dismutase (SOD) activity, leading to increased production of H 2 O 2 , that with superoxide (O 2 À ), forms highly reactive OH À radicals in leaf cells (Saruyama and Tanida, 1995). Chilling tolerance in plant species is closely related to the capacity of anti-oxidation systems in leaf cells, which consist of oxidative free-radical scavenging enzymes [e.g.…”

Background Field observations and glasshouse studies have suggested links between boron (B)-deficiency and leaf damage induced by low temperature in crop plants, but causal relationships between these two stresses at physiological, biochemical and molecular levels have yet to be explored. Limited evidence at the whole-plant level suggests that chilling temperature in the root zone restricts B uptake capacity and/or B distribution/utilization efficiency in the shoot, but the nature of this interaction depends on chilling tolerance of species concerned, the mode of low temperature treatment (abrupt versus gradual temperature decline) and growth conditions (e.g. photon flux density and relative humidity) that may exacerbate chilling stress.Scope This review explores roles of B nutrition in chilling tolerance of continual root or transient shoot chills in crop species adapted to warm season conditions. It reviews current research on combined effects of chilling temperature (ranging from >0 to 20 C) and B deficiency on growth and B nutrition responses in crop species differing in chilling tolerance.Conclusion For subtropical/tropical species (e.g. cucumber, cassava, sunflower), root chilling at 10-17 C decreases B uptake efficiency and B utilization in the shoot and increases the shoot : root ratio, but chilling-tolerant temperate species (e.g. oilseed rape, wheat) require much lower root chill temperatures (2-5 C) to achieve the same responses. Boron deficiency exacerbates chilling injuries in leaf tissues, particularly under high photon flux density. Suggested mechanisms for B · chilling interactions in plants are: (a) chilling-induced reduction in plasmalemma hydraulic conductivity, membrane fluidity, water channel activity and root pressure, which contribute to the decrease in root hydraulic conductance, water uptake and associated B uptake; (b) chilling-induced stomatal dysfunction affecting B transport from root to shoot and B partitioning in the shoot; and (c) B deficiency induced sensitivity to photo-oxidative damage in leaf cells. However, specific evidence for each of the mechanisms is still lacking. Impacts of B status on chilling tolerance in crop species have important implications for the management of B supply during sensitive stages of growth, such as early growth after planting and early reproductive development, both of which can coincide with the occurrence of chilling temperatures in the field.
