Abstract

Trichoderma fungus species are highly populations of fungi in world that they can colonize roots as plant symbiosis. Various types of Trichoderma are free-living fungi that are, generally, saprophytic on the remains of soil. In addition to its role in biological control, this fungus increases plant yield and growth. So far, many studies have been conducted to examine the ability of this agent to reduce biological tensions and biological control of plant pathogens. Thus, this study was conducted to isolate and identify species of Trichoderma fungus from rapeseed fields in Golestan and Qazvin province from Iran, and also to study isolated species on germination percentage and growth parameters of rapeseed seedlings in a randomized complete block design with three replications in vitro. Based on the results, three species of T. harzianum, T. virens, and T. atroviride were identified, which the isolate of T. harzianum Ta19 showed a significant effect on the control group and other treatments in increasing germination percentage, root length and stem; whereas, the seeds treated with the isolate T. atroviride Ta11 showed no significant difference with the control group in spite of the increase in seed germination rate in comparison with the control and other treatments. According to the results, the use of Trichoderma fungus as a seed treatment like other researches on different products is recommended for increasing the growth of rapeseed.

Abstract

The effect of different methods of NANO-GRO® application on tomato plant growth and yield and its quality was determined. Four treatments were used: soaking seeds with NANO-GRO®, plants spraying, double application: soaking seeds + plants spraying and a control without NANO-GRO®. The cultivar Mieszko F1 was used for the study. A significant influence of NANO-GRO® application method on tomato plant growth, yield and quality was observed. Pre-sowing application positively influenced plant height and the thickness of the stems. The highest total and marketable yield was observed in plants whose seeds were soaked with NANO-GRO® (respectively 87.02 and 53.13 t ha−1) and in those with double application (respectively 73.48 and 45.67 t ha−1). The lowest marketable yield was found in the plants from the control (37.01 t ha−1). The highest lycopene content compared to the control was measured in fruits from plants sprayed with NANO-GRO®.

Summary

Plants have to cope with a number of biotic stresses among which, infectious diseases. The present study was conducted to investigate the reaction of two native Greek tomato vars, ‘Chondrokatsari Messinias’ and ‘Katsari Santorinis’, to infection by Fusarium oxysporum f. sp. lycopersici and Rhizoctonia solani. Disease symptoms, disease incidence and severity were recorded and the effects of infection on the number of flowers, the biomass production (fresh and dry weight), CO2 assimilation, stomatal conductance and transpiration were also evaluated. Both tomato varieties were susceptible to F. oxysporum f. sp. lycopersici and R. solani infection. However, ‘Chondrokatsari Messinias’ was found to be less susceptible to F. oxysporum f. sp. lycopersici compared to ‘Katsari Santorinis’. Both pathogens negatively affected biomass production of var. ‘Chondrokatsari Messinias’ but not that of ‘Katsari Santorinis’. The number of fl owers produced by ‘Chondrokatsari Messinias’ was negatively affected by R. solani but not by F. oxysporum f. sp. lycopersici. Infection of both varieties by R. solani also caused reduction in the CO2 assimilation, stomatal conductance and transpiration.
