The effect of soaking cowpea (Vigna unguiculata) for 2 h in aerated solution of different antioxidants; ascorbic acid (AsA) and gallic acid (GA), each at 0.0, 50, 100, 150, 200, 250 and 300 ppm, sodium selenate (NaSeO4) and nanoselenium (SeNPs ≈ 33.4 nm) chemically prepared, each at 0.0, 6.25, 12.5, 25, 50 and 100 μM on seedling length and activities of some hydrolytic enzymes were tested. Seeds of treated and untreated cowpea were germinated at 25°C ± 0.5 under dark controlled conditions for 4 days. Results showed that AsA, GA, NaSeO4 and SeNPs at low concentrations significantly improved plumule and radicale lengths compared with their corresponding controls. Moreover, AsA and GA up to 150 ppm, NaSeO4 and SeNPs up to 25 μM significantly increased the activities of α-amylase, β-amylase and protease enzymes as well as the contents of total soluble sugars and total soluble proteins. The results indicate the successful use of ascorbic acid and gallic acid up to 150 ppm as well as sodium selenate and nanoselenium up to 25 μM in enhancing seedling growth and hydrolytic enzymatic activity in cowpea germinated seeds.Further promising results on the effect of these compounds on vegetative growth and yield can be concluded from the previous results on germination and seedling growth.","PeriodicalId":16817,"journal":{"name":"Journal of Plant Physiology & Pathology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76178444","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}

Similar to elsewhere in the world, pesticides are used to boost agricultural production in Malaysian farms. However, chemical pesticides are associated with human health hazard and are not environmentfriendly as they persist in nature for long periods of time. \u0000Materials and methods: \u0000In this cross-sectional study, we surveyed 19 palm oil plantations in the Sabah district of Malaysia and evaluated the perception of the workers towards pesticide use and their awareness regarding the health effects associated with pesticide exposure. \u0000Results and discussion: \u0000Our analysis shows that most of the workers among the 270 respondents were 30-year-old males with average education, and belonged to the low income group. Majority opined that they were aware of the health hazards of pesticide use and suffered from symptoms (with mean duration of three days) such as vomiting, diarrhea, skin irritation, and dizziness. Surprisingly, the opinion was almost equally divided on whether they perceived pesticides to be the cause of their health problems, and a major percentage did not avail of medical help. Most of the workers responded that they did not receive any training in pesticide handling. Interestingly, they would not read the safety material even if it was provided. \u0000Conclusion: \u0000We concluded that the farmers should also be educated about alternative and eco-friendly ways of farming. Finally, the plantation management should intervene and proactively advocate the use of safe farming practices.","PeriodicalId":16817,"journal":{"name":"Journal of Plant Physiology & Pathology","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80132639","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}

In order to determine whether the distribution pattern of mineral nutrients is correlated with the Huanglongbing (HLB) disease status, leaf and pulp samples were collected from fifteen healthy and HLB-affected cultivars of citrus from the Sargodha district of Pakistan. Samples were removed from the field-grown trees and their HLB status determined by quantitative PCR. The levels of zinc (Zn), phosphorous (P), and potassium (K) were measured by inductively-coupled plasma mass spectrometry. Pulp tissues contained lower levels of all three minerals regardless of the infection status. No significant change (t-test) was found in K levels associated with the HLB-affected leaves (p=0.7843) or pulp (p=0.0997). Phosphorous decreased 9% (p=0.0437) in leaves and increased 29% (p=0.0120) in pulp in HLB-affected samples compared to healthy. Zn showed a 31% (p<0.0001) decrease in infected leaves but no change in the pulp tissue (p=0.6728). These results indicate that the partitioning of Zn and P between leaves and fruit was differently affected by the HLB-infection status of the tree. However, no relationship between HLB infection status and K was observed.","PeriodicalId":16817,"journal":{"name":"Journal of Plant Physiology & Pathology","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91329712","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}
