Salinity, a severe environmental factor, has limited the growth and productivity of crops. Many compounds have been applied to minimize the harmful effects of salt stress on plant growth. An experiment was conducted to investigate the interactive effects of exogenous ascorbic acid (AsA) and gibberellic acid (GA 3 ) on common bean (Phaseolus vulgaris L. cv. Naz) seedlings under salt stress. The changes of growth parameters, photosynthetic and non-photosynthetic pigments and potassium content showed that the addition of 1 mM AsA and/or 0.05 mM GA 3 considerably decreased the oxidative damage in common bean plants treated with 200 mM NaCl. The NaCl-stressed seedlings exposed to AsA or GA 3 , specifically in their combination, exhibited an improvement in sodium accumulation in both roots and shoots, as compared to NaCl-treated plants. NaCl treatment increased hydrogen peroxide (H 2 O 2 ) content and lipid peroxidation indicated by accumulation of malondialdehyde (MDA), whereas the interaction of AsA with GA 3 decreased the amounts of MDA and H 2 O 2 . In the meantime, interactive effect of these substances enhanced protein content and the activity of the antioxidant enzyme, guaiacol peroxidase, in common bean plants under salt stress. It was concluded that synergistic interaction between AsA and GA 3 could alleviate the adverse effects of salinity on P. vulgaris seedlings.

Increasing climatic variability is projected to affect large-scale atmospheric circulation, triggers and exacerbates more extreme weather events, including winter warming and more frequent extreme low temperatures in spring. Historical data from 1961-2000 indicate these temperature fluctuations may seriously affect grain yield of winter wheat crops. In this study, a field air temperature control system (FATC) was used to simulate the winter warming, spring cold and freezing events in the field experiment in 2010-2011 to explore their impacts on growth and yield of winter wheat. Eight elite wheat varieties released during 1961-2000 were included and four temperature scenarios were applied, including late spring freeze alone, winter warming + late spring freeze, early spring cold + late spring freeze and the normal temperature condition as control. Winter warming combined with late spring freeze significantly decreased tiller survival rate, leaf photosynthetic rate and leaf growth in wheat plants, and reduced the spike number and kernel number per spike, and the final grain yield. In contrast, the wheat plants experienced early spring cold had higher tiller survival rate, leaf photosynthetic capacity and sugar accumulation and improved tolerance to the late spring freeze, resulting in less yield loss, as compared with those without experiencing early spring cold. Both the meta-analyses and the field experimental data demonstrated that the effects of later spring freeze stress on wheat yield were exacerbated by winter warming but were extenuated by early spring cold events. Therefore, it is important to consider the characteristics of temperature fluctuations during winter to spring for precise evaluation of climate change effects on wheat production.

Mechanisms on inhibition of photosynthesis in Kandelia obovata due to extreme cold events under climate change

Introduction: Mangroves that grow at the latitudinal extremes of their distribution are susceptible to extreme cold events. Successive enhancement of low temperature stress (seLTS) is a typical characteristic of extreme cold events. Low temperature stress can inhibit mangrove photosynthesis, which often inhibits the growth and development of mangroves. However, the possible reasons for impairment to photosynthesis of mangroves due to extreme cold events remain unclear. Methods: Kandelia obovata seedlings in a growth chamber were exposed to 5°C/−2°C (day/night) for 36 h (−2°C for 16 h) with 12 h light per day at 600 μmol m −2 s −1 photosynthetic photon flux density (PPFD) (a low temperature stress, aLTS), then the plants were transferred to the control condition (15°C/10°C (day/night) and allowed to recover for 5 days (R1). The other seedlings were subjected to low temperature treatment with a day/night temperature of 5°C/−1°C in a growth chamber for 24 h. Then these plants were transferred to 5°C/−2°C (day/night) under the same light and climate conditions for 36 h (two low temperature stresses, tLTS). Following the successive enhancement of low temperature treatment, these plants were returned to 15°C/10°C (day/night) for another 5-day recovery period (R2).
