During the growing seasons of 2009 and 2010, same tomato fields throughout Marvdasht  were visited  and  96 isolates of Fusarium spp. were collected from root, crown and stem of diseased tomato plants. Isolates were identified as based on morphological characteristics. They were divided into four species namely: Fusarium solani, F. pseudoanthophilum, F. oxysporum and F. equiseti. These species,...

Among the most important quality parameters of irrigation water used for greenhouse crops, alkalinity of water is considered critical due to its impact on pH of soil or growing medium solution. In this study, shoot and root Fe contents and SPAD index were investigated in non-grafted and grafted tomato (greenhouse tomato) plants onto five rootstocks (eggplant, datura, orange nightshade, local Ir...

introduction: mycorrhizal symbiosis is one of the most popular and highest symbiotic relationship in plant kingdom. most plants (about 80% of vascular plant species) have at least one type of mycorrhiza. arbuscular mycorrhizal fungies are the most important endomycorhiza fungi that play an important role in agriculture. materials and methods: in order to evaluate the effect of arbuscular mycorr...

Root-knot nematodes cause physiological and anatomical disorders in plants. The present study contains the results of an investigation of the effect of Meloidogyne incognita race2 on the growth of roots and aerial organs of tomato under greenhouse conditions. The experiment in a completely randomized design split split plot on two susceptible (Falat Y) and tolerante (Gina VF) tomatoes variety w...

Salinity plays an important role in the reduction of tomato growth, especially in arid and semi-arid regions. Nitrogen (N) may increase tomato tolerance to salt stress by increasing plant growth. In order to investigate the interaction effect of salinity and nitrogen on tomato growth, fruit quality, and micronutrient concentration in tomato plants, a hydroponic experiment was conducted in a com...

Oxamyl was coated on carrot (Daucus carota L. cv. Spartan Fancy-80) and tomato (Lycopersicon esculentum Mill. cv. Glamour) seeds with a polymer sticker for the control of Meloidogyne hapla. The sticker diluted in water 1:1 delayed carrot seedling emergence. Oxamyl at 40 mg/ml in a 1:5 dilution of sticker lowered the rate of carrot seedling emergence until day 13 and plant growth until day 28. O...
