Therefore, a study was carried out to ascertain the effects of terminal heat stress on 40 genotypes of Indian wheat with respect to 7 physiological and 6 agronomic parameters. Using chemometric analysis, such as principal component analysis (PCA), agglomerative hierarchical cluster analysis (AHC), and heat maps, the genotypes were grouped. Based on AHC and heat maps, the genotypes were divided into three clusters: tolerant, moderate, and sensitive. Tolerant genotypes such as DBW14, RAJ 3765, WH730, NW1014, and HALNA exhibited improved physiological response in terms of membrane stability index (MSI), chlorophyll content (CHL), photosynthesis rate (PN), antioxidative performance, and yield attributes under heat stress conditions while genotypes like Chirya7, HW2004, and many others were found to be relatively heat sensitive. Physiological traits like MSI, CHL, Proline, catalase (CAT), and PN were found to be the main determinants of genotype group assignments and showed positive correlations with grain yield. The results indicated that Thousand-grain weight (TGW), Grain yield (GY), and MSI could be used for the identification and assortment of heat-tolerant genotypes. In conclusion,thousand-grain weight (TGW) can be employed as a final assessment of heat tolerance after harvest. The findings also suggest that tolerant genotypes such as DBW 14, RAJ 3765, WH730, NW1014 HALNA, HI1563, and WH730 can be employed to develop climate-resilient varieties for India or other countries experiencing high-temperature stresses (HTS) at their terminal stage.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140196855","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}

Experimental variants included 0, 1, 2, and 4 mM concentrations of putrescine as foliar spraying and mycorrhizal fungi, with and without mycorrhizal inoculation. The amount of mycorrhiza inoculation was 60 g per pot. Gerbera plants were transplanted into pots with or without mycorrhizal inoculation. Two weeks after the establishment of the plant and mycorrhizal fungus, foliar spraying of putrescine was performed every 15 days during a three-month period. In this experiment, morphological features such as fresh and dry weight of the root, pedicel length and diameter, the volume of the root, absorption of nutrients, including phosphorus, potassium, calcium, and nitrate, as well as post-harvest features, including relative fresh weight, solution absorption rate, and phenylalanine ammonia-lyase enzyme activity, underwent investigation. The findings demonstrated that putrescine, along with mycorrhizal fungi, had a positive effect on the growth characteristics of Gerbera, could increase nutrient absorption, and improve post-harvest indicators.

Since several plant physiological and biochemical relationships under drought conditions remain unknown, it may be possible to obtain more drought-tolerant plants by knowing these details. An effective management strategy involves the use of exogenous substances, increasing the expression of resistant genes, and increasing the production of enzymes that help the plant to withstand damaging environmental conditions such as drought. Experimental treatments consisted of four levels of irrigation regimes and foliar application of abscisic acid (ABA) at two concentrations, with three replicates. The results showed that drought in 30–40% field capacity increased the antioxidant activity by DPPH, ABTS, FRAP, and TAOC methods; and the antioxidant enzymes of catalase (CAT), superoxide dismutase (SOD), peroxidase (POX), and ascorbate peroxidase (APX), significantly. Foliar application of ABA on <i>Lavandula angustifolia</i> cv. Munstead improved plant metabolism under stress conditions, mildly. So that, the interaction between drought and ABA had a synergistic effect on antioxidant activity and related enzymes. The expression of <i>CAT</i>, <i>POD</i>, and <i>APX</i> genes decreased under drought stress, while spraying ABA ameliorated this decrease. The expression of the <i>SOD</i> gene tended to decline, and no drought treatment along with 15 μM ABA spraying revealed the highest expression. Hormone spraying, on the other hand, had a positive effect on this expression under stress compared to the control (no spraying). Overall, despite the unknown details of how radical scavenging functions in plants and the associated expression, these results suggest that ABA treatment reduced the inhibitory effects of drought stress and increased the tolerance of lavender under stress conditions.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140150949","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}

Canola, a vital crop, is particularly susceptible to environmental challenges at any stage of development, which can have a negative impact on its growth, physiology, and pod formation, ultimately resulting in pod shattering and reduced yield. Canola's rate of return is decreased by mechanical harvesting, which results in pod shattering. The establishment of an abscission layer, triggered by enzymatic and hormonal disruptions, and accompanied by a decline in cell wall stickiness, exacerbates pod shattering. In this context, the potential roles of Paclobutrazol and silver nanoparticles in reinforcing pod strength to withstand shattering. The specific doses of both AgNPs and Paclobutrazol could be done on the aerial parts of plant. These elements facilitate the physiological growth of crops by mitigating the adverse effects of stress on canola, thereby reducing pod shattering and enhancing yield output. This critical review aims to comprehensively explore the physiological, enzymatic, and hormonal-based factors contributing to pod shattering under environmental stresses, while also highlighting the potential mitigation techniques employing Paclobutrazol and silver nanoparticles, to elevate canola yield production.

The sensitivity of wheat (<i>Triticum aestivum</i> L.) to heat stress is a major constraint limiting wheat production.

We phenotyped a mini panel of thirty diverse wheat genotypes under optimum and low planting densities. Staggered sowing was done to expose the late-sown genotypes to a higher temperature at the terminal growth stage. Heat wave occurred during March–April, 2022, resulting in late sown genotypes being exposed to a staggering 6.6 °C/4 °C higher day/night temperature during flowering and early grain filling stage, as compared to normal sown genotypes. Heat stress caused significant loss in biomass (34.46%), grains spike⁻¹ (22.34%), test weight (15.52%), and grain yield (28.67%) in late-sown genotypes as compared to normal-sown genotypes. Conversely, genotypes grown under low planting density showed substantial variations in growth parameters including plant height, tillering, thicker leaves, and canopy cover. Interestingly, genotypes with denser canopy and thicker leaves could avoid high day temperature-induced losses by maintaining lower canopy and spike temperatures, which eventually resulted in higher grains spike⁻¹. However, the impact of higher night temperature on biomass and seed weight was not affected by denser canopy and lower spike temperature. Hence, yield loss was majorly confined to high night temperature. The study suggests that higher night temperature could be a major determinant of yield under naturally occurring heat waves.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140046706","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}
