“…However, the change of V K is not only affected by injury on the PSII donor side, but also by damage on PSII acceptor side. When the injury on the acceptor side is greater than that on the donor side, V K does not increase significantly (Zhang et al, 2018c;Zhang et al, 2019b). Therefore, although the electron transfer from Q A to Q B on the PSII acceptor side of blueberry leaves was inhibited by low temperature, low temperature had little effect on the oxygen-evolving complex of the PSII donor side as V K did not change.…”

“…Non-stomatal factors, such as the decrease of photosynthetic enzyme activity under stress, are also important factors that limit plant photosynthesis. Under severe stress, non-stomatal factors often play a major role in limiting plant photosynthesis (Zhang et al, 2019b). At the 5 th day of low temperature stress, the C i increased significantly ( Figure 8D), indicating that the reason for the decrease of photosynthetic capacity caused by long-term (5 d) low temperature stress was due to the limitation of nonstomatal factors (Arena and Vitale, 2018;Zhang et al, 2019a) Exogenous H 2 S can promote the transport of CO 2 (Espie et al, 1989), the expression of photosynthesis-related enzymes, and the redox modification of thiol groups to improve photosynthesis Application of exogenous H 2 S can also promote the protein and gene expression of Ribulose-1,5-Bisphosphate Carboxylase (Rubisco) and phenol pyruvate carboxylase in maize leaves under iron deficiency conditions (Chen et al, 2011).…”

In this study, we investigated the mechanism of photosynthesis and physiological function of blueberry leaves under low temperature stress (4-6°C) by exogenous hydrogen sulfide (H 2 S) by spraying leaves with 0.5 mmol·L -1 NaHS (H 2 S donor) and 200 mmol·L -1 hypotaurine (Hypotaurine, H 2 S scavenger). The results showed that chlorophyll and carotenoid content in blueberry leaves decreased under low temperature stress, and the photochemical activities of photosystem II (PSII) and photosystem I (PSI) were also inhibited. Low temperature stress can reduce photosynthetic carbon assimilation capacity by inhibiting stomatal conductance (G s ) of blueberry leaves, and non-stomatal factors also play a limiting role at the 5 th day of low temperature stress. Low temperature stress leads to the accumulation of Pro and H 2 O 2 in blueberry leaves and increases membrane peroxidation. Spraying leaves with NaHS, a donor of exogenous H 2 S, could alleviate the degradation of chlorophyll and carotenoids in blueberry leaves caused by low temperature and reduce the photoinhibition of PSII and PSI. The main reason for the enhancement of photochemical activity of PSII was that exogenous H 2 S promoted the electron transfer from Q A to Q B on PSII acceptor side under low temperature stress. In addition, it promoted the accumulation of osmotic regulator proline under low temperature stress and significantly alleviated membrane peroxidation. H 2 S scavengers (Hypotaurine) aggravated photoinhibition and the degree of oxidative damage under low temperature stress. Improving photosynthetic capacity as well as alleviating photosynthetic inhibition and oxidative stress with exogenous H 2 S is possible in blueberry seedlings under low temperature stress.

“…This indicated that the reduction of photosynthetic activity caused by decreased light absorption for photochemistry and increased PSII negative reaction centers of H. jubatum seedlings occurred under the three stresses and seemed more easily affected by alkali stress. The possible reason is that the high pH of NaHCO 3 much more harmed photosynthesis by damaging oxygen-evolving complex (OEC) on the donor side of PSII, and hindered the electron transfer on the PSII acceptor side ( Zhang et al, 2019 ). Moreover, the ΦPSII and q p values of the three stresses much decreased when the water potential was below −0.47 MPa, especially under alkali stress, indicating that the photosynthetic system was more easily influenced by stresses under lower water potential.…”

Uniform Water Potential Induced by Salt, Alkali, and Drought Stresses Has Different Impacts on the Seedling of Hordeum jubatum: From Growth, Photosynthesis, and Chlorophyll Fluorescence

Hordeum jubatum is a halophyte ornamental plant wildly distributed in the Northeast of China, where the low water potential induced by various abiotic stresses is a major factor limiting plant growth and development. However, little is known about the comparative effects of salt, alkali, and drought stresses at uniform water potential on the plants. In the present study, the growth, gas exchange parameters, photosynthetic pigments, and chlorophyll fluorescence in the seedlings of H. jubatum under three low water potentials were measured. The results showed that the growth and photosynthetic parameters under these stresses were all decreased except for carotenoid (Car) with the increasing of stress concentration, and alkali stress caused the most damaging effects on the seedlings. The decreased net photosynthetic rate (Pn), stomatal conductance (Gs), and intercellular CO2 concentrations (Ci) values under salt stress were mainly attributed to stomatal factors, while non-stomatal factors were dominate under drought and alkali stresses. The reduced chlorophyll and slightly increased Car contents occurred under these stresses, and most significant changed under alkali stress. In addition, the maximum photochemical efficiency (Fv/Fm), actual photochemical efficiency (ΦPSII), and photochemical quenching coefficient (qP) under the stresses were all decreased, indicating that salt, alkali, and drought stresses all increased susceptibility of PSII to photoinhibition, reduced the photosynthetic activity by the declined absorption of light for photochemistry, and increased PSII active reaction centers. Moreover, the non-photochemical quenching coefficient (NPQ) of alkali stress was different from salt and drought stresses, showing that the high pH of alkali stress caused more damaging effects on the photoprotection mechanism depending on the xanthophyll cycle. The above results suggest that the H. jubatum has stronger tolerance of salt than drought and alkali stresses, and the negative effects of alkali stress on the growth and photosynthetic performance of this species was most serious.

“…Furthermore, artichoke appearance, taste, and sensory qualities were unsatisfactory when inactivation was performed using NaHCO 3 . In conclusion, Jerusalem artichoke tubers were damaged by NaHCO 3 stress to a much greater extent than they were in response to NaCl stress, as evidenced by the oxidative damage in mulberry seedling leaves (Zhang et al, 2019(Zhang et al, , 2020.…”

“…NaHCO 3 has been widely used in analytical, synthetic, pharmaceutical, medical, and food fermentation. It does not alter the dry weight of the cells in the fermentation system during vegetable curing, but it significantly increases the rate of glucose consumption (Zhang et al, 2019). According to Figure 2, a 10-16% solution of NaHCO 3 can inactivate inulinase during Jerusalem artichoke pickling.…”

Freshly harvested Jerusalem artichoke tubers contain inulinase, an enzyme that requires inactivation, because of its ability to hydrolysis inulin into fructose, which can be consumed by microorganism during marination. As the traditional pickling process takes 6 months, and involves the addition of a large amount of salt (18–20%), this production strategy is uneconomical and increases the nitrite intake. Additionally, miscellaneous bacteria produced during pickling affect the product taste. In this study, the enzyme inactivation effects of NaCl, NaHCO3, and ultrasound were evaluated. NaHCO3 treatment results in the highest degree of enzyme inactivation; however, the quality and flavor of the obtained Jerusalem artichoke pickles were not ideal. The Jerusalem artichoke pickles in which the enzymes were inactivated using a combination of NaCl and ultrasound exhibited better flavor than those exposed to NaHCO3; further, this combination reduced the inulinase activity of the Jerusalem artichokes to 2.50 U/mL, and maintained the inulin content at 61.22%. The strains LS3 and YS2, identified as Enterococcus faecalis and the salt-tolerant yeast Meyerozyma guilliermondii, respectively, were the dominant microorganisms isolated from the pickle juice. Jerusalem artichokes with inactivated inulinase were pickled with microbial powder, separated, purified, and dried to remove the natural Jerusalem artichoke sauce. This process shortened the fermentation cycle and improved product quality.
