Item How may trichoderma application affect vegetative and qualitative traits in tulip darwin hybride cultivar(Uludağ Üniversitesi, 2011) Mazhabi, Morteza; Nemati, Hossein; Rouhani, Hamid; Tehranifar, Ali; Moghadam, Esmat Mahdikhani; Kaveh, HamedTo study the effect of Trichoderma harzianum Bi on qualitative and quantitative traits of tulip including stem length and diameter, bud diameter, petal length, bulb perimeter and bulblet number, an experiment based on completely randomized design with 8 replications were completed in situ. Main media mixture was 40% of coco peat+ 40 of field soil+ 20% of perlite. Treatments included enriched coco peat with trichoderma in different concentrations (0, 20, 50 and 100%) of total coco peat. Results showed that 100 and 50% of enriched coco peat significantly increased stem length and diameter. These treatments also had an effect on bud diameter significantly. Petal length was also affected by 100% of enriched coco peat treatment in comparison to control. All treatments (20, 50 and 100%) had a significant effect on bulblet appearance in both mature and immature bulbs. Mature bulb perimeter was significantly affected by all treatments although immature bulb perimeter was only affected by 50 and 100% treatments. Flower bud formation in immature bulbs which was treated with 50 and 100% of enriched coco peat increased significantly in comparison to control. Totally it seems that trichoderma increases tulip cut flower quality traits and induces maturity in immature bulbs.Item Would trichoderma affect seed germination and seedling quality of two muskmelon cultivars, khatooni and qasri and increase their transplanting success?(Uludağ Üniversitesi, 2011) Kaveh, Hamed; Jartoodeh, Safieh Vatandoost; Aruee, Hossein; Mazhabi, MortezaIn order to investigate effect of Trichoderma harzianum Bi on seed germination and seedling quality and field establishment of two muskmelon cultivars, Khatooni and Qasri, different tests was done at greenhouse and field. 4 concentration of trichoderma solution, control (0), 25%, 50% and 100% (Mazhabi 2010) in a factorial experiment with a completely randomized design and ten replications with 10 seeds in each replication placed in Petri-dishes to evaluate germination percentage and germination index. Emergence tests were carried out in seedling trays which were filled with enriched coco peat in 4 different concentrations, and then emergence percentage and index calculated during two weeks. Four weeks after emergence of first seedling, 5 seedlings per replication were selected randomly and shoot length and diameter, length of longest root and total dry weight of plugs measured. , successful transplantation percentage (STP) evaluated using two methods of trichoderma application in 4 different concentrations. Results show that trichoderma application significantly increased germination and emergence percentage and index and could help improving seedling health and vigor.STP was significantly affected by trichoderma application and 1st method of application had better results.
