AIM: To examine the possible protective effect of Satureja khuzistanica essential oil(SKE) on antioxidant enzyme activity in alloxan-induced Type 1 diabetic rats. METHOD: Thirty Sprague-Dawley male rats were divided into three groups randomly; group one as control, group two diabetic, with no treatment, and group three treatment with SKE at 500 ppm in drinking water, respectively. Diabetes was induced in the second and third groups by alloxan injection subcutaneously. After eight weeks, animals were anaesthetized. Blood samples were also collected before killing to measure antioxidant enzymes activity. RESULTS: SKE significantly increased the serum level of glutathione and the serum activity of glutathione peroxidase, superoxide dismutase, and catalase in the treated group compared with the diabetic untreated group. CONCLUSION: The findings showed that SKE exerts beneficial effects on the antioxidant enzymes activity in alloxan-induced Type 1 diabetic rats.

Continuous cropping obstacles hamper the efficient growth and yield of Szechuan pepper,Zanthoxylum simulans.The current study investigated the impact of different levels of bioorganic fertilizer on the leaf physiological and photosynthetic characteristics of Z.simulans to provide a theoretical reference for continuous Z.simulans crop cultivation.A bioorganic fertilizer was used to treat seedlings growing in 25-year-old continuous cropping soil.Five fertilizer treatments were applied.The impacts of the treatments on the activity of defense enzyme and photosynthetic parameters of Z.simulans leaves were determined.The different concentrations of bioorganic fertilizer reduced to varying degrees the malondialdehyde(MDA)content and intercellular CO2 concentration(Ci),and increased the activity of peroxidase(POD),superoxide dismutase(SOD),and ascorbate peroxidase(APX),as well as the chlorophyll content,net photosynthetic rate(Pn),stomatal conductance(Gs)and transpiration rate(Tr)of Z.simulans leaves.The results showed that most significant increases or decreases were achieved with 100 g/L bioorganic fertilizer(Y2).Thus,the application of bioorganic fertilizer at a rate of 100 g/L can significantly improve the activity of relevant defense enzymes and photosynthetic parameters of Z.simulans,and reduce the MDA content,enhancing the stress resistance of the plants,promoting their growth and addressing,to some extent,obstacles associated with continuous cultivation.

Background:Soil acidification caused by acid rain(AR)can damage plant roots,which in turn negatively impacts plant health.In response to changing AR types,research efforts to elucidate their specific impacts on plants have become intense.Methods:For this study,we investigated the effects of simulated sulfuric,nitric,and mixed AR on the root systems of Quercus acutissima Carr.and Cunninghamia lanceolata(Lamb.)Hook.under different acidity levels.Results:As the AR S/N ratio and pH decreased,the height growth rate(HGR),basal diameter growth rate(DGR),total root length(TRL)and total root surface area(TRS)of C.lanceolata decreased,whereas the TRL and TRS of Q.acutissima remained the same.When the NO_(3)^(−)concentration in AR was increased,the root activity,superoxide dismutase(SOD)and catalase(CAT)activities of C.lanceolata roots revealed a downward trend;however,the root activity of Q.acutissima and the peroxidase(POD)activity of C.lanceolata roots revealed an upward trend.Further,redundant analysis and structural equation models indicated that AR pH had a greater impact on the HGR of Q.acutissima than that of C.lanceolata,while the impact of the AR S/N ratio on C.lanceolata growth rates was greater than that of Q.acutissima.Conclusions:Our results suggested that the root systems of different tree species had variable responses to AR,and the AR S/N ratio was an important factor affecting plant root growth.This might facilitate new strategies for the culti‑vation and protection of plantations in the future.

Wheat straw burial has great potential to sustain rice production under alternate wetting and drying(AWD)irrigation.A field experiment was conducted with three wheat straw burial treatments,including without straw burial(NSB),with light straw burial of 300 kg/hm^(2)(LSB)and dense straw burial of 800 kg/hm^(2)(DSB),as well as three AWD regimes:alternate wetting/moderate drying(AWMD),alternate wetting/severe drying(AWSD)and alternate wetting/critical drying(AWCD).The rice growth and grain quality were higher in LSB and NSB than those in NSB under the same AWD regime.The AWMD×DSB treatment resulted in the highest yield,brown rice rate,milled rice rate,amylose content and protein content.Conversely,the AWCD×NSB treatment led to the lowest yield,brown rice rate,milled rice rate,amylose content and protein content.The active absorption area and nitrate reductase activity of roots were higher in the AWMD×DSB treatment than those in the AWCD×NSB treatment,as the former increased organic carbon and nitrogen contents in the rhizosphere,whereas the latter reduced their availability.Total soluble protein content and glutamine synthetase activity were greater in the AWMD×DSB treatment than those in the AWCD×NSB treatment.The activities of superoxide dismutase and catalase were higher in the AWMD×DSB treatment compared with the AWCD×NSB treatment,leading to the amelioration of oxidative cell injury,as shown by a lower malonaldehyde level.This study suggested that farmers should implement AWMD irrigation after leaving the straw residues in the field,followed by deep tillage to improve soil quality and mitigate the drought stress cycles of AWD.This approach can improve rice growth and grain quality and alleviate the problems of disposal of straw residues and water scarcity for sustainable rice production.

Agricultural soil contamination by cadmium (Cd) is becoming one of the most serious environmental issues and public concerns. In this study, factorial arrangements of treatments were designed to explore the effects of two soil amendments, sodium sulfide-biofuel ash (SSBA) and lime (0.1%), and three foliar applications, silicon (Si, 2.5 mmol L-1), selenium (Se, 40 mg L-1), and their combination (SS), on Cd reduction in rice (Oryza sativa L.) in a pot experiment, which were then verified in a field experiment. Compared with the control without amendment but with spraying of deionized water, both SSBA and lime significantly reduced concentrations of CaCl2-extractable Cd in soil by 30%–39% and 31%–40% and Cd in brown rice by 44%–63% and 53%–72% in the pot and field experiments, respectively. Foliar Si, Se, and SS applications significantly reduced Cd accumulation in brown rice by 62%–64%, 72%–83%, and 39%–73%, respectively, increased rice grain yield, and improved antioxidant enzyme activities in rice leaves but with different trends in the pot and field experiments. Combinations of SSBA and lime with Si, Se, and SS had a non-significant synergistic effect on Cd reduction in brown rice compared to only foliar spraying or soil amendment in both pot and field experiments, although SSBA + Se and SSBA + Si reduced Cd concentration in brown rice by 16%–34% and 14%–24% compared to only foliar Si and Se and soil SSBA applications, respectively. Soil lime application and foliar Si spraying were the most cost-effective strategies to reduce Cd accumulation in brown rice in the field and pot experiments, respectively. Although soil amendments and foliar treatments were individually effective, their combinations failed to generate a significant synergistic reduction of Cd concentration in brown rice.

In order to explore the effects of brackish water combined with regulated deficit irrigation of different growth periods,different levels of water,and salt synergistic stress on the characteristics of ion absorption,distribution,transport,and antioxidant enzyme activity of tomatoes,a greenhouse pot experiment was applied.The influencing factors were set as:irrigation water salinity(local shallow groundwater S01.1 g/L,S12.0 g/L,S24.0 g/L),different water deficit levels(W170%-80%field capacity(FC),W260%-70%FC,W350%-60%FC),and three growth stages(T1 seedling stage,T2 blossoming and bearing fruits stage,T3 mature picking stage).Monitoring and analyzing the dynamic changes of K^(+)and Na^(+)content in tomato root stems and leaves under water-salt stress and antioxidant enzyme activities of leaves at the seedling stage.The results showed the coordinated regulation of water and salt can significantly change the ion absorption of roots and the transfer between stems and leaves at different growth stages.The roots and leaves of tomatoes mainly accumulated K^(+),and the stems mainly accumulate Na^(+).The increase of irrigation salinity can reduce the ratio of K^(+)/Na^(+)ratio in leaves.Under the coordinated regulation of water and salt,K^(+)became the main osmotic adjustment ion of the leaves again.The activities of catalase,superoxide dismutase,and peroxidase in tomato leaves increased with the increase of water-salt stress.The results have great significance to the response of crops and to meet the requirements for water quality and quantity of brackish water under water-salt stress at different growth stages of tomatoes.

We carried out a pool culture experiment to determine the optimal water treatment depth in loam and clay soils during the late growth stage of super rice. Three controlled water depth treatments of 0-5, 0-10 and 0-15 cm below the soil surface were established using alternate wetting and drying irrigation, and the soil water potential （0 to -25 kPa） was measured at 5, 10 and 15 cm. A 2-cm water layer was used as the control. We measured soil enzyme activities, root antioxidant enzyme activities, chlorophyll fluorescence parameters, and rice yield. The results showed that the 0-5-cm water depth treatment significantly increased root antioxidant enzyme activities in loam soil compared with the control, whereas soil enzyme activities, chlorophyll fluorescence parameters and yield did not differ from those of the control. The 0-10- and 0-15-cm water depth treatments also increased root antioxidant enzyme activities, whereas soil enzyme activities, chlorophyll fluorescence parameters and yield decreased. In clay soil, the soil enzyme activities, root antioxidant enzyme activities, chlorophyll fluorescence parameters, and yield did not change with the 0-5-cm water treatment, whereas the 0-10- and 0-15-cm water treatments improved these parameters. Therefore,the appropriate depths for soil water during the late growth period of rice with a 0 to -25 kPa water potential were 5 cm in loam and 15 cm in clay soil.

Button mushroom(Agaricus bisporus)is sold well for its unique flavour and nutritional benefits.However,the mushroom flavour deteriorates quickly during storage because of its delicate structure and high moisture.In this study,the effects of nitric oxide(NO)application on flavour compounds and antioxidant enzyme activities of stored button mushrooms were investigated.The button mushrooms were immersed in the NO donor sodium nitroprusside(15μmol/L)for 3 min and then stored under the condition of 4℃,90%relative humidity for 12 days.Results showed that the treated mushrooms have reduced weight loss rate,uniform white colour,and higher firmness during storage.Compared to the control,the ketones,alcohols,esters,and aldehydes in the NO-treated button mushroom increased sharply at 3 days of storage and then showed a continuing decline trend,except ester compounds which reached the peak value at 6 days of storage.In addition,NO treatment increased the total phenolics and catalase activity and inhibited the polyphenol oxidase activity in the stored button mushroom.These results indicated that NO treatment is an alternative storage technology to enhance antioxidant capacity and maintain flavour and consumer acceptance of stored button mushroom.
