Severe drought stress is a chief threat to wheat productivity in existing climatic variations. Screening of wheat cultivars based on metabolic strategies to tolerate drought stress is crucial to ensure better yield. Current research work is carried out to evaluate drought-sensitive and tolerant wheat cultivars based on physio-biochemical and morphological stress indices. A pot experiment was organized according to factorial CRD with four replications. Ten latest high-yielding wheat cultivars were selected, and seeds were sown in pots having loamy soil and divided into two treatment portions. One was treated with control (NoDS) conditions, and the other with severe drought conditions (DS). Drought stress caused a significant decline in fresh and dry weight of roots and shoots, length of roots and shoots, leaf area and chlorophyll contents. However, enhanced production of reactive oxygen species (H 2 O 2 ) and lipid peroxidation (MDA) ultimately triggered enzymatic antioxidant (SOD, POD, CAT) activities. All wheat cultivars exhibited osmotic modification by accumulating total soluble proteins (TSP) and free amino acids (FAA). According to our findings, Akber-19 performed better under control (NoDS) conditions among all cultivars. However, it is quite sensitive under severe drought (DS) stress. In contrast, Fakhar-e-Bhakkar significantly maintained osmotic and antioxidative balance under drought stress (DS) and exhibited more tolerant behaviour than other cultivars at the seedling stage.","PeriodicalId":19962,"journal":{"name":"Pakistan Journal of Botany","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136204830","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}

Phosphorous is an essential macronutrient element that greatly contributed to the growth and yield of wheat crops. Proper phosphorous concentration and suitable sowing methods are involved in increased growth, yield, and nutrient profiling of the wheat crop. An experiment was performed at Central Cotton Research Institute, Multan, to evaluate the application of phosphorous and different sowing methods on three different wheat cultivars i.e. Gandum-1, Sehar-2006 and Faisalabad-2008. The experiment was performed to study the impact of four different phosphorous levels (control, 60kg ha -1 , 120 kg ha -1 , 180kg ha -1 ) on three different wheat cultivars by using three different sowing methods i.e. flat, drill and bed sowing. A randomized complete block design was used to perform the experiment. Present results indicated that leaf area index, leaf area duration, crop growth rate, net assimilation rate; plant height, spike length, number of spikelets, fertile tillers, number of grains per spike, 1000 grain weight, grain yield, biological yield, harvest index, phosphorous content, protein content, oil content and chlorophyll content were significantly increased in cultivar Faisalabad-2008, phosphorous 180 kg ha -1 and bed sowing method. From present results, it has been concluded that Faisalabad-2008 is a higher yielding cultivar grown on bed sowing method with the application of phosphorous 180 kg ha -1 and this combination is more suitable to attain higher yield in the future.","PeriodicalId":19962,"journal":{"name":"Pakistan Journal of Botany","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48924913","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}

Present study describes the allelopathic effect of Euphorbia hirta L. on physical and physiological aspects of Cicer arietinum L. Weed powder have significantly affected plant height, fresh and dry mass whereas, chlorophyll (a and b), carotene and protein contents are gradually decreased as the amount of weed increased up to a maximal of 20g of weed powder. Highest inhibition has observed in 20g. Protein contents have been greatly disrupted by allelopathic influence as well as chlorophyll contents while carotenes have been synthesized in greater amount with the increase in manure concentration. PAGE analysis has produced highest bands of proteins in control sample whereas, 20 gram weed powder showed lowest number of bands. MANOVA computation released highly significant ( p <0.001) differences among the samples. The soil samples show significant ( p <0.01) effectiveness of pH that can be a factor for allelopathic response from soil and plant growth. It can be concluded that E. hirta has produced inhibitory effects on plant growth, specifically responsible for protein damage and deactivation of chlorophyll content.","PeriodicalId":19962,"journal":{"name":"Pakistan Journal of Botany","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42708161","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}

(Mung bean) is an edible leguminous plant that has adapted to different environmental conditions and possesses many varieties and local formas. Agronomic traits and nutrient compositions change depending on genotype and environmental conditions. In the present study, changes in agronomic properties, qualitative properties, and nutrient composition of 7 mung bean genotypes grown at different altitudes (L1: 1050 m, L2: 314 m) in two different locations [Isparta (L1) and Mersin (L2)] were investigated. It was found that there were significant differences between genotypes in both locations in terms of all characteristics examined in the study. In the study, it was found that the L2 location was superior in terms of agronomic characteristics. Water absorption capacity and swelling index were higher in the L2 location, while fat content, protein ratio, ash content, and carbohydrate content were higher in the L1 location. In terms of mineral element content, phosphorus, magnesium, and iron were higher in the L1 location, whereas calcium, copper, and zinc were higher in the L2 location, and potassium and manganese were not affected by locations. Examining both locations, the G2 genotype was superior in terms of agronomic characteristics, the G6 genotype was superior in terms of quality characteristics, and the G5 genotype was superior in terms of mineral content characteristics compared to other genotypes. Also, it was found that growing mung beans at low altitudes was more advantageous in terms of yield and yield components. However, it was found that the quality and nutrient composition of mung beans grown at higher altitudes were higher.","PeriodicalId":19962,"journal":{"name":"Pakistan Journal of Botany","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44303126","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}
