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 investigations presented here were carried out in years 2013-14, in a Molinietum caeruleae meadow with interrupted plant cover caused by animal activity (patch I); abandoned Molinietum caeruleae meadows with untouched plant canopy, dominated by species with considerable height of the above-ground parts (patches II-VI); as well as the edge (patch VII) and the interior (patch VIII) of a birch woodlot. The height of standing vegetation and soil moisture increased in subsequent patches, whereas the light availability at ground level showed inverse tendency. The abundance of Trollius europaeus subpopulations in all studied patches was rather low. In patch I, juvenile individuals dominated, while in other stands - flowering adults prevailed. The lack of temporal variability in the number of basal leaves observed in patches III, IV, V, VI and VII might be due to lack of available area necessary for clonal proliferation of ramets, while the increase of basal leaves number in other sites might suggest unlimited iterative growth. The dimensions of basal leaves in consecutive years were constant in majority of subpopulations, while they showed strong spatial variability increasing gradually from patch I to patch VII and, subsequently, decreasing in patch VIII. The substantial dimensions of basal leaves may enable better light capture in sites with great level of lateral shade, while smaller dimensions in patches located within a woodlot may be due to shade from above created by trees. Lack of temporal variability and presence of substantial spatial variability in the number and height of generative stems, as well as flower production might enhance chances for successful pollination in a competitive environment. Significant changes of follicle number in time and space suggest successful process of pollination in all patches excluding patch VIII. The weak condition of the ramet clusters in patch I is not compensated by considerable seedling recruitment, whereas the satisfactory state of the ramet clusters in patches II-VIII may not suffice for the long-term maintenance of populations in colonized areas.

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®.
