The findings showed that water scarcity stress lowered grain weight and shoot dry weight (ShDW) by decreasing leaf area (LA), Fv/Fm, chlorophyll, and carotenoid content, while increasing catalase activity (CAT), ascorbate peroxidase activity (APX), guaiacol peroxidase activity (GPX), 2,2-diphenyl-1-picrylhydrazyl scavenging capacity (DPPH), and leaf proline content (LPC). The effect of water deficit on the measured traits varied depending on the CO₂ concentration. On average, the effect of water deficit stress on decreasing grain weight and LA, and increasing root dry weight (RDW), APX, LPC, and DPPH under ambient CO₂ was greater than under elevated CO₂. Furthermore, the impact of elevated CO₂ on the studied traits was dependent on the soil moisture profile. Its effect on increasing ShDW and RDW was greater under control conditions, while its effect on decreasing APX, DPPH, Chla, Chlb, and Car content was greater under water deficit conditions. The effects of water stress and elevated CO₂ were also found to be cultivar-specific. Principal component analysis revealed relationship among genotypes and traits. In summary, selecting wheat cultivars should be done separately for different CO₂ and water conditions due to their varied responses. Cultivars #22 (Hidhab) and #16 (Sistan) perform well under ambient CO₂ and control soil moisture, while #22 (Hidhab) and #5 (Karaj) show potential for adapting to different CO₂ and soil moisture levels, resulting in significant grain weight. These cultivars hold promise for future research studies. Consequently, it is critical to consider atmospheric CO₂ levels when designing breeding and yield improvement programs for wheat cultivars under changing climate conditions, as it affects their drought tolerance traits.</p>","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"36 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139028457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nitrogen metabolism plays a crucial role in determining the growth, development, and quality of rice grains. This study investigates the effects of nitrogen application rates on the enzymatic activities related to nitrogen metabolism, nitrogen metabolites, and grain protein content in the premium-tasty japonica rice variety, Suxiangjing 100. Using a range of nitrogen application rates (0, 80, 160, 240, 320, and 400 kg per hectare), comprehensive analyses were conducted across various developmental stages. Results indicate that as nitrogen application increased, there were distinct patterns in the enzyme activities and metabolite concentrations related to nitrogen metabolism in the leaves of premium-tasty japonica rice. The activities of nitrate reductase (NR), glutamine synthetase (GS), and glutamate synthase (GOGAT) peaked at moderate nitrogen applications, while excessive nitrogen led to a decrease in their activities. The activity of Glutamate Dehydrogenase (GDH) generally increased, but showed a decline after the filling stage. With increasing nitrogen application, the concentrations of nitrate nitrogen (NO₃–N), ammonium nitrogen (NH₄–N), free amino acids (FAA), and soluble proteins (SP) initially rose but declined at excessive application rates. The grain protein content increased, with levels of prolamin, glutelin, and globulin peaking at nitrogen applications of 240 kg/ha and 320 kg/ha, while changes in albumin levels were minimal.

The germination parameters studied were germination kinetic, precocity of germination (PG), final germination rate (FGR), germination speed (GS) and germ's length (LG).

Globally, maize (<i>Zea mays</i> L.) loses a substantial amount of its production due to very high temperatures at anthesis stage during spring season. So, development of heat tolerant maize cultivars is important for maize breeders. The ability of a plant to tolerate heat stress at seedling and reproductive stage is linked with each other and screening at the seedling stage could accelerate the selection process. In the present study, 50 maize inbred lines were screened for heat tolerance at seedling stage under in vitro conditions. Our results showed that parameters such as root length (RL), shoot length (SL), shoot fresh weight (SFW), shoot dry weight (SDW), root fresh weight (RFW), root dry weight (RDW), leaf area (LA), leaf fresh weight (LFW), leaf dry weight (LDW), relative water content (RWC), membrane stability index (MSI) and total chlorophyll (TCHL) showed a significant decrease under heat stress (<i>p</i> &lt; 0.05). Further, morpho-physiological traits were delineated by principal component analysis (PCA). Hierarchical cluster analysis (HCA) was done with the objective to characterize the maize inbred lines based on their response under heat stress. Among the four column clusters, column cluster I showed highest mean values for maximum traits, i.e., RL (16.45 cm), RFW (0.27 g), SL (28.42 cm), SFW (0.74 g), SDW (63.03 mg), LFW (0.16 g), LDW (20 mg) and RWC (48.63%), suggesting that these traits were superior over other traits and inbred lines falling in this cluster would be selected directly on the basis of these traits. The heat tolerance index (HTI) of all the inbred lines based on individual traits was calculated and inbred lines were ranked accordingly. The top five inbred lines: LM22, CML579, LM13, LM16 and RIL 33 performed best under heat stress as they had high heat tolerance index value. The results obtained by PCA and HCA were in accordance with those obtained on the basis of HTI.

PCA identified seven components that account for almost 74% of the total variability in grain yield and shoot fly resistance. Two of the most reliable components (PC1 and PC2) were strongly correlated with a number of traits, including deadhearts per cent (21 and 28 DAE), seedling vigour, number of eggs per plant and trichome density on upper and lower surfaces, fodder yield per plot, fodder yield per plant, days to maturity and days to 50% flowering.

In the cold treatment, the survival rate and strong seedling index first increased and then decreased with decreasing water content, and the cold tolerance of seedlings was the best when the water content was 45%. The mechanism of improving the cold tolerance is that moderate water deficit improved the antioxidant enzyme activity, reduced the content of malondialdehyde and improved root activity and leaf photosynthetic performance. Correlation analysis showed that the survival rate of seedlings was significantly positively correlated with root activity, antioxidant enzyme activity and seedling quality in the control temperature and cold treatment.
