Wounding experiment was performed by small punctures either on the midrib or leaf lamina. Results showed that damage by wounding elicited a rapid increase in H2O2 levels within the first few hours of wound stress. H2O2 levels, total phenolic and flavonoid levels were significantly higher in midrib damage than either the lamina damage or control conditions. Wounding pre-treatment reduced the toxic effects of NaCl stress in plants. Alleviation of salt induced damage was greater in midrib cuts through the stabilization of relative water content and also an increase in antioxidant scavenging activity. These results confirm that wounding pre-treatment induced cross-tolerance to salinity stress in tomato plants. It is suggested that an early and significantly elevated generation of H2O2 with local midrib injury could induce a priming response systemically, thereby providing protection to the subsequent salt stress injury.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42691446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is used as food, fodder, fixes atmospheric nitrogen, stabilizes sand dunes and its fruits are consumed fresh as well as after drying. Pods were sampled at 5 developmental stages viz., S1(3.5 cm), S2 (5.7 cm), S3 (9.2 cm), S4 (15.3 cm), S5 (17.4 cm, naturally dried pods on tree) to evaluate the changes in phytonutrients (total sugars, reducing sugars, protein and total phenol) and antioxidant activity in terms of DPPH radical scavenging activity, nitric oxide scavenging and ferric reducing power assay during fruit development from S1 to S5. Total soluble sugar content increased from S1 stage (47.1 mg-1f.wt.) to S5 stage (64.28 mg-1f.wt.), reducing sugar and sucrose content also increased from 20.65 mg-1f.wt to 29.45 mg-1f.wt and 18.75 to 33.84 mg-1f.wt, respectively. Free amino acid and protein content increased during the development of the pods from very young to ripened stage. Whereas, total phenol content (TPC) was high at S1 stage (229.59 mg-1f.wt.) as compared to S5 stage (55.24 mg-1 g.f.wt.). DPPH radical scavenging activity decreased from 78.46 to 22.72 % during fruit development but ferric reducing activity increased with maturity of the pods. The study is significant in evaluating phytochemical and antioxidant activities of the fruits that are consumed in every season by the local rural people. This study may help in prioritization of these local underutilised fruits as they are rich in some of the phytonutrients and antioxidants.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48441914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It causes significant losses (up to 80 %) in seed as well as bulb crops. The synthetic fungicides are the only option available to farmers for its management, which in long run may result in resistance development in pathogen. So there is a need to find novel strategies for management of this disease, hence the present study was devised to evaluate the antifungal efficacy of plant extracts from eight medicinally important plant species. The test fungus S. vesicarium was isolated from symptomatic leaf samples and was identified by characteristics of spore from available literature. Methanolic extracts of selected plants at three different concentrations (0.1, 0.5 and 1.0 %) were evaluated against S. vesicarium using poison food technique under in vitro conditions. The results showed that all plant extracts exhibited statistically significant antifungal efficacy from each other ( P < 0.05). But Origanum vulgare at 0.5 and 1 % concentration exhibited highest antifungal efficacy (68.23 % and 81.3 % respectively). The importance of the present study lies in that the oregano extracts had the potential to manage the disease under field conditions after isolation of bioactive molecule and development of proper formulation. To the best of our knowledge this is the first kind of study conducted, where oregano has been reported to be effective against plant pathogen.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44235559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Growth regulator treatments included 50, 150 and 300 ppm gibberellic acid (GA3) and naphthalene acetic acid (NAA) . Saffron corms weighing 8 to 10 g were immersed in solutions of GA3 and NAA and then were planted in 1×1 meter plots with 15 cm within row and 20 cm between row spacing. At the end of the growing season (end of June), crop traits such as total number and weight of the produced corms and the number and weight of produced corms in weighing groups of less than 4 g, 4 to 8 g, and more than 8 g were measured by harvesting one third of the cultivated corms in each plot. At the flowering time of the remaining corms of each plot (November), weight and number of flower, fresh and dry weight of stigma, and the amount of active ingredients including crocin, picrocrocin and safranal were measured. The results showed that all studied traits were affected by growth regulator compounds and indicated significant (P≤0.01 and P≤0.05) differences with control. GA3 improved biological yield and corm weight, in addition it could increase the quality of stigma compared to the control treatment. Application of 150 ppm GA3 increased the weight of corms by 16.25 % and the number of flower plot-1 by 34.99 % compared to the control treatment. Also, 300 ppm GA3 increased the dry stigma yield by 37.5 % compared to the control treatment. NAA did not affect yield production significantly and at high concentrations, prevented the growth of corms and flower production. Results indicated that concentrations higher than 150 ppm GA3 can increase the yield of saffron, and can play an important role in enhancement of saffron farms productivity.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48273279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The greenhouse research was conducted in the Agrotechnopark of the University of Brawijaya at Jatikerto Village, Kromengan Sub-District, Malang Regency. The utilized research method was Completely Randomized Nested Design consisting of two factors. The first factor was the concentration of nutrient solution consisting of 100 % (3.5 dS m-1), 75 % (2.6 dS m-1), and 50 % (1.8 dS m-1) concentrations. The second factor is the inoculation of biological agents consisting of no inoculation of biological agents, PGPR (Plant Growth Promoting Rhizobacteria), AMF (Arbuscular Mycorrhizal Fungi), and PGPR + AMF. The data were analyzed using an analysis of variance and continued with the test of Honest Significant Difference at 5 % level. The results showed that the interaction between the types of biological agents and nutrient concentrations significantly increased the number of flowers, number of fruits, fruit weight, fruit diameter, and sugar content of cherry tomatoes. The AMF application showed the highest fruit weight per plant and fruit diameter, especially at 100 % nutrient concentration. The AMF application also showed a higher sugar content compared to the control and PGPR but not significantly different from the PGPR + AMF treatment at all levels of given nutrient concentration. Fruit weight per plant with treatment of AMF, PGPR + AMF, and PGPR respectively produced 64.47, 48.75 and 29.39 % higher than without application of biological agents.","PeriodicalId":39205,"journal":{"name":"Journal of Applied Horticulture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43523231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
