Effective and environmentally friendly methods of protection to reduce seed contamination from fungi are constantly sought. The use of thermal impulses of 100 °C wet water steam to reduce fungal contamination has not been sufficiently investigated, and the potential of this physical approach has not been estimated.The aim of the study was to investigate what impact 100 °C wet water steam with different time durations had on acorn contamination with fungi, acorn germination and biometric indicators of English oak (Quercus robur) seedlings during the first year of growth. Different treatment durations with wet water steam were used: 2, 4, 6, 8, 10, 12 and 14 s.Research showed that 6 seconds impact of wet steam on the surface of the oak acorn destroyed Alternaria spp., 8 seconds impact destroyed Penicillium spp. and 14 seconds impact destroyed Mucor spp. Using 14 seconds water steam treatment Penicillium, Alternaria and Mucor spp. fungi were eliminated.Wet water steam treatment for 2 - 4 seconds not only stimulated the acorns germination by 4.0 - 7.6%, but also had positive influence on the root collar diameter of seedlings. Wet water steam treatment for 2 - 12 seconds had a positive effect on the root development of oak seedlings, however, high temperature environment had a suppressive effect on the oak seedling height.

“…Although winter sowing improves yields, it is rarely adopted in Mediterranean regions because the cool and wet conditions also favour Ascochyta blight. Other minor diseases of chickpea are more geographically localised and include pod borer (Helicoverpa armigera) in Australia and India (Nene and Reddy 1987), botrytis grey mould in areas that favour overgrowth and dense canopy , root rots in the tropics and sub-tropics (Kraft et al 2000), rust in high-altitude regions (Nene and Reddy 1987) and broomrape in winter-sown areas (Rubiales et al 1999).…”

Abstract. Chickpea is a valuable and important agricultural crop, but yield potential is limited by a series of biotic and abiotic stresses, including Ascochyta blight, Fusarium wilt, drought, cold and salinity. To accelerate molecular breeding efforts for the discovery and introgression of stress tolerance genes into cultivated chickpea, functional genomics approaches are rapidly growing. Recently a series of genetic tools for chickpea have become available that have allowed high-powered functional genomics studies to proceed, including a dense genetic map, large insert genome libraries, expressed sequence tag libraries, microarrays, serial analysis of gene expression, transgenics and reverse genetics. This review summarises the development of these genomic tools and the achievements made in initial and emerging functional genomics studies. Much of the initial research focused on Ascochyta blight resistance, and a resistance model has been synthesised based on the results of various studies. Use of the rich comparative genomics resources from the model legumes Medicago truncatula and Lotus japonicus is also discussed. Finally, perspectives on the future directions for chickpea functional genomics, with the goal of developing elite chickpea cultivars, are discussed.

“…Usually soil-borne pathogens are associated with damping-off in the earlier stages, whereas in the latter stages seed-borne pathogens can indorse damping-off. However, both explanations understand that damping-off includes inhibition of seeds germination or seedling emergence after germination, or rotting and breakdown of seedlings over the soil (Kraft et al 2000). Cotton seedling disease complex sources of serious economic losses in several production countries annually.…”

The current study was undertaken to evaluate the influence of various fungicidal treatment on the inhibition percent of pathogens and as seed treatment on cotton seedling stand establishment against root rot of cotton in in vitro as well as in field conditions at Sakha Agriculture Research Station during two seasons 2019 and 2020. This study was carried out to evaluate once more available fungicides, for their effectiveness against the root rot pathogens (Rhizoctonia solani ,Fusarium oxysporum and Macrophomina phaseolina). And upon it evaluate which of them for used it as seed treatment. All tested fungicides exhibited reduction in the radial growth of mycelium for all the testing fungi significantly compare with control. Hymexazole and Tebuconazole + fludioxnile showed excessive decreased of mycelial growth, when Hymexazole; Tebuconazole + fludioxnile; Carboxin + thiram; Triticonazole and Fludioxanile + mefenoxam (metalaxyl-m) gave best results in the reduction percent of inhibition) for the three tested pathogens. Efficiency of fungicide seed treatments were expressed as increased in standing percent; plant height and dry weight of plant. Disease incidence was very low in both Propanocarb HCl + fostyl Al and Fludioxanile + mefenoxam (metalaxyl-m). Generally, the fungicide treatments ended a little or no difference in plant height or dry weight. Under the field conditions (low disease pressure), results indicated that, fungicide seed treatments are slightly effective in increasing standing percent. Diniconazole-M was the most effective in disease reduction (expressed as 100% standing percent). These treatments were translated into increased plant height and dry weight of plants.
