Item How salinity affect germination and emergence of tomato lines(Uludağ Üniversitesi, 2011) Kaveh, Hamed; Nemati, Hossein; Farsi, Mohammad; Jartoodeh, Safieh VatandoostPHigh salt concentrations in soil and irrigation water restrict establishment and growth of tomato (Solanum lycopersicum). Correcting saline condition in field and greenhouse would be expensive and temporary while selection and breeding for salt tolerance can be a wise solution to minimize salinity effects as well as improve production efficiency. In order to find any kind of tolerance to saline condition, effects of four salinity levels in irrigation water (0.5, 2.5, 5, and 10 ds·m−1 ) on seed germination and seedling emergence, and growth of tomato lines LA3770, R205, CT6, Fla, and ME were investigated in a greenhouse. Germination percentage and rate, emergence percentage and rate of all tomato lines were delayed and decreased by salinity increasing from 2.5 ds·m−1 to 10 ds·m−1 . All seedling growth characters, except seedling height, were decreased with increasingly salinity levels. At germination and emergence stage, LA 3770 were more tolerant to salinity than others.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.
