Identification of Microsatellite Markers Linked with Genomic Regions Involved in Resistance to Basal Stem Rot Disease Isolates in Oily Sunflower (Helianthus annuus L.) under Controlled Conditions
Sunflower (Helianthus annuus L.) is an important crop that its oil has nutritional and high economic value. Basal stem rot, caused by Sclerotinia sclerotiorum and S. minor, is one of the important and devastating disease of sunflower. The use of resistant cultivars is considered as the most important and effective method to control the disease. In this study, the reaction of 100 oily sunflower ...
متن کاملField Applications of Some Bioagents and Safety Chemicals to Control Stem Rot Disease of Jerusalem artichoke (Helianthus tuberosus L.)
Four bioagents i.e. yeast (Saccharomyces cerevisiae), Trichoderma viride, Bacillus subtilis, and Pseudomonas fluorescens in addition to humic acid, sulphated canola oil (sulphex 0.5%) and Paclobutrazol (PBZ) were applied to study their effect on disease incidence caused by Sclerotium rolfsii. Also, some vegetative parameters, tuber yield and enzymes activity of Jerusalem artichokes (Helianthus ...
متن کاملIntraspecific variation in embolism resistance and stem anatomy across four sunflower (Helianthus annuus L.) accessions.
Drought-induced xylem embolism is a key process closely related to plant mortality during extreme drought events. However, this process has been poorly investigated in crop species to date, despite the observed decline of crop productivity under extreme drought conditions. Interspecific variation in hydraulic traits has frequently been reported, but less is known about intraspecific variation i...
متن کاملTransfructosidation in extracts of the tubers of Helianthus tuberosus L.
The silage specimens on which data are reported were from grass and grass-clover mixtures ensiled during the summer of 1950 on various farms in the northeast of Scotland, and were taken at random from specimens being analysed here. It is seen from Fig. 2 that the lactic acid content of silage falls rapidly with rise ofpH. This is in accordance with the generally held view that in silage of pH g...
متن کاملTOLERANCE OF SUNFLOWER (Helianthus annuus L.) TO IMAZETHAPYR
The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid "Zoltan" (S) was investigated under controlled conditions. Hybrids grown in pots were treated post-emergence with imazethapyr at the two pairs of leaves stage. Visual injury evaluation and vegetative parameters were recorded. ALS (acetolactate synthase) enzyme activ...
