Drought and heat cause 60% and 40% wheat yield losses by altering the physiology of the crop. Understanding the impact of these stresses on wheat physiological traits can help in developing tolerant genotypes. Forty-two genotypes were evaluated under non-stress (TSIR-NS), drought (TSRF-DR), and heat stress (LSIR-HT) for two crop seasons. The experiments were laid in rectangular lattice (6 × 7) design with two replications. Data for grain yield and various physiological traits were recorded at GS70 and GS75. Grain yield (GY) was reduced by 29.0%, 16.4% under heat, and by 48.7% and 30.2% under drought stress during the two seasons. Heat susceptibility index (HSI) and drought susceptibility index (DSI) of these genotypes ranged from 0.3 to 1.8 and 0.4 to 1.4. Among the top five high-yielding lines under TSIR-NS, only one (G39) was drought tolerant, while under LSIR-HT, four high-yielding lines (G40, G41, G04, and G35) of the top five genotypes were heat tolerant. Conversely, the top five high-yielding lines under TSRF-DR were drought tolerant. Overall, 21 lines were tolerant to heat stress and 22 to drought and 12 genotypes were tolerant to both stresses. Chlorophyll was higher under LSIR-HT and TSRF-DR. Normalized difference vegetation index at GS70 (NDVIA) and normalized difference vegetation index at GS75 (NDVI15DAA) suffered a drastic reduction under TSRF-DR. The stomatal conductance (gs) and transpiration (E) were greatly reduced under drought and increased under LSIR-HT. Assimilation (A) and photosynthetic water use efficiency (WUE) were reduced under heat stress. The correlation of physiological traits with GY was also calculated. The traits chlorophyll fluorescence at GS70 (CFLA), NDVI 15DAA, and E contributed toward GY under TSIR-NS, CFLA, NDVI15DAA, WUE, Canopy temperature at GS75 (CT15DAA), and gs under TSRF-DR, and A, NDVIA, CFLA, and chlorophyll fluorescence at GS75 (CFL15DAA) under LSIR-HT. CFLA contributed toward GY under all environments. Finally, traits such as A, E, WUE, and CFL15DAA were impacted by both stresses, while NDVIA and NDVI15DAA and gs were only affected by drought and CFLA and CTA were only influenced by heat stress.</p>","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"14 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138517671","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}

Studies were conducted to understand the vulnerability of stored millets to different grain insects such as lesser grain borer <i>Rhyzopertha dominica</i> (Fab.), red flour beetle <i>Tribolium castaneum</i> (Herbst), and Angoumois grain moth <i>Sitotroga cerealella</i> (Oliv.) under free-choice as well as no-choice conditions at Post Harvest Technology Centre, Bapatla, Andhra Pradesh, India. Red flour beetles could multiply in significantly higher numbers in pearl millet flour in both free-choice and no-choice conditions (413.33 and 340.67 adults, respectively) followed by foxtail millet (276.0 adults) and sorghum (299.33 adults), respectively. Pearl millet was the most preferred by lesser grain borer with as many as 133.67 insects moving into the grain followed by sorghum (95.33 adults) under free-choice conditions. A mean total of 316.67 grain moths emerged from proso millet under free-choice conditions. On the other hand, finger millet and little millet were not preferred and resulted in emergence of very few moths (0.33 and 3.67 moths, respectively). Little millet and finger millet grains were less susceptible to both coleopteran and lepidopteran insects. Millet grains were analyzed for the physical parameters such as grain moisture, 1000-grain weight, grain volume, hardness, porosity, and the biochemical constituents such as protein, carbohydrates, total phenols, and tannins to understand their influence on insect preferences. Though significant correlations could not be drawn between the progeny development of insects and the physicochemical characteristics of grains, little millet and foxtail millet were found to be less preferred particularly by the internal feeders due to their smaller grain size. Pearl millet possessed higher amounts of sugars and proteins compared to other millets which might have contributed to insect preference.</p>","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"47 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138516705","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}

Cadmium (Cd) is particularly hazardous to humans and accumulates in agricultural soils due to industrial activities and natural sources. Even if Cd adversely affects plant growth and vital functions, few studies have investigated its effects on durum wheat, an important staple crop. Therefore, this study aimed to understand the morphological alteration induced by Cd during the germination phase of durum wheat (<i>Triticum durum</i> L<i>.</i>) seeds to evaluate the tolerance of three cultivars (Karim, Nachit, and Louiza) to Cd stress. The experiment involved germinating wheat seeds in nine concentrations of Cd (0, 0.125, 0.25, 0.375, 0.5, 0.675, 0.75, 0.875, 1 g/L) where germination rate, biomass production, shoot and root length, vigor index, growth inhibition, and tolerance indices were assessed. The different treatments were arranged using a completely randomized design. The results showed that Cd negatively affected wheat germination. The minimum effect of Cd on germination percentage was recorded at 0.125 g/L of Cd for Nachit and Louiza, and at 0.25 g/L of Cd for Karim, while the maximum inhibition was noticed starting at 0.625, 0.875, and 0.625 g/L of Cd for Karim, Nachit, and Louiza, respectively. The negative effect of Cd on shoot and root length was more pronounced during seedling development than during germination. Cd had a greater effect on root length than on shoot length, with Louiza being the most affected cultivar. However, Cd had no significant effect on fresh and dry weight. Our research reveals that the presence of Cd pollution has a substantial impact on the initial growth stages of durum wheat with differential responses of the studied cultivars when exposed to Cd stress. These alterations in seedlings’ performances strongly emphasize the importance of evaluating Cd’s effects on plant development and fitness. This underscores the significance of this aspect not only for ensuring the health of our crops but also for safeguarding food quality in the presence of HM pollution.</p>","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"7 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138516701","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}

The screening was conducted in trays under less humid condition (50% RH) in April 2019 (referred as E1) and in the field under high humid condition (72% RH) in July 2019 (referred as E2). The susceptible plants showed stunting in E1 and elongation in E2.

Multi-locus GWAS using 159 lines of global rice diversity panel identified 11 QTLs on seven different chromosomes. In the 11 QTL regions, 40 putative genes were identified based on stringent filtering and relevance to the disease.

Thus, this research was conducted to evaluate antioxidant enzyme expression in response to hydric stress at the reproductive stage in upland rice genotypes. Three genotypes from the upland rice breeding program on agreement between UFLA, EPAMIG, and EMBRAPA, CMG2093, CMG2172, and BRSMG Relâmpago, were used as controls. Genotypes were grown under field conditions with supplementary irrigation during the whole crop cycle, and hydric stress was induced in the reproductive phase before panicle emission. Seedlings were used in enzyme analyses from the emergence test and IVE on substrate (soil + sand at a 2:1 rate) at 70% and 10% field capacity. Significant differences were observed among genotypes for vigor tests.

Drought stress was imposed by stopping the irrigation before anthesis and post-anthesis stages. Different traits related to physiological adaptations, earliness, grain yield and starch contents were decreased under drought stress except amylose which increased significantly. Canopy temperature depression was not significantly affected by drought stress. Further, we identified strong correlation of grain yield with plant height, normalized difference in vegetation index, plant maturity, spike length, grain number and thousand grain weight but negative with canopy temperature depression.
