Crop Damage from Sclerotinia Crown Rot and Risk Factors in Pyrethrum
Scott, J. B., Gent, D. H., Pethybridge, S. J., Groom, T., and Hay, F. S. 2014. Crop damage from Sclerotinia crown rot and risk factors in pyrethrum. Plant Dis. 98:103-111. Sclerotinia crown rot, caused by Sclerotinia sclerotiorum and S. minor, is a prevalent disease in pyrethrum fields in Australia. Management involves fungicide applications during the rosette stage of plant development from au...
متن کاملExpression Pattern of the Synthetic Pathogen-Inducible Promoter (SynP-FF) in the Transgenic Canola in Response to Sclerotinia sclerotiorum
Sclerotinia sclerotiorum is a phytopathogenic fungus which causes serious yield losses in canola. A pathogen inducible-promoter can facilitate the production of Sclerotinia-resistant transgenic canola plants. Inthis study, the “gain of function approach” was adopted for the construction of a pathogen-inducible promoter.The synthetic promoter technique was used, which involved the in...
متن کاملStudy of Correlations betweenHorticultural Traits and Variables Affecting Kernel Percentage of Walnut (Juglans regia L.)
Studies of physiological diversity and its effect on the expression of traits in plants are used in breeding programs as a selective tool with the aim of selecting special attributes for creating a new product. In this study, the correlation coefficients among 17 horticultural traits of 34 genotypes from 11 different places of Semnan province were examined. A significant positive correlation wa...
متن کاملGenetics of Resistance and Pathogenicity in the Maize/Setosphaeria turcica Pathosystem and Implications for Breeding
Northern corn leaf blight (NCLB), the most devastating leaf pathogen in maize (Zea mays L.), is caused by the heterothallic ascomycete Setosphaeria turcica. The pathogen population shows an extremely high genetic diversity in tropical and subtropical regions. Varietal resistance is the most efficient technique to control NCLB. Host resistance can be qualitative based on race-specific Ht genes o...
متن کاملThe influence of temperatures on germination and seedling growth of pyrethrum (Tanacetum cineraiifolium) under drought stress
Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...
