Additionally, by reducing the chlorophyll amount and the level of fatty acids without impacting the UFAs, DBI and PSII efficiency, recovered olive plants tend to adjust its chloroplast and membrane structures to a new state of reorganization to prevent future membrane damage. Nonetheless, these extensive modulations appeared to occur at the expense of regrowth, particularly in salt-recovered plants.

This study aimed to investigate the effects of hydration and dehydration (HD) cycles at different temperatures on the germination and initial development of <i>Crotalaria retusa</i> seedlings under water deficit conditions. HD cycles were simulated as pre-germination treatments, and the seeds were subjected to 0, 1, 2, or 3 cycles at 25, 30, or 40 °C. After germination, the seedlings were subjected to 10 days of water suppression (water deficit) and 10 days of recovery. The results showed that HD cycles and temperature had a positive effect on germination, although higher temperatures and more cycles decreased germinability. Seedling growth was reduced in the combination of HD cycles, temperature, and water deficit, which can be a strategy of tolerance to water stress by plants. The passage through HD cycles promoted changes in germination and development of <i>C. retusa</i>, which can aid in the process of invasion of the species in arid and semi-arid environments and can bring competitive benefits in relation to native species.

The aim of this experiment was to evaluate the impact of arbuscular mycorrhizal fungi on the photosynthetic physiology of strawberries under salinity stress. The greenhouse experiment involved the strawberry cultivar ‘Benihoppe’, which was inoculated with <i>Glomus mosseae</i> under three salt stress levels (0 mM, 30 mM, and 60 mM). Subsequently, the results showed that salinity stress led to a significant decline in leaf area, fresh biomass, and photosynthetic characteristics of the strawberries. Under salt stress, especially at the concentration of 60 mM. Pn, Gs, Tr, Ci, Fv/Fm, and NPQ showed significant differences. After inoculation of AMF, arbuscular mycorrhiza established a beneficial symbiotic relationship with strawberry roots, which effectively reduced salt damage and promoted the growth of strawberry plants. Leaf area, fresh biomass, and relative chlorophyll content were significantly increased. Pn, Tr, and Gs of mycorrhizal strawberry were significantly higher than those of control group. In addition, the light energy conversion efficiency of strawberry plants inoculated with AMF was improved, thus increasing the potential photosynthetic capacity and photosynthetic rate of strawberry.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":"46 12","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142714409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
