Host nutritional variables were evaluated for their effects on the severity of crown and root rot of tomato caused by Fusarium oxysporum f.sp. radicis-lycopersici. Tomato (Lycopersicon esculentum Mill.) seedlings (cv. Bonnie Best) were grown in a pathogeninfested, soilless rockwool system in the greenhouse and were fertilized with a nutrient solution that was amended with macroand microelements...

Micropropagated plants are usually cultured in in vitro environments, with a high relative humidity and low light intensity, taking nutrients and energy from the culture medium. During acclimatization, physiological and structural changes allow micropropagated plants to adapt to the new environmental conditions, mainly to low relative humidity and high light intensity. As a result, plants becom...
