Abstract
Soil-borne pathogens cause significant losses in agricultural production all over the world and are particularly difficult to predict, detect, diagnose and successfully control.
Different methods of soil-borne disease control exist in horticultural field including: crop rotation, steam soil disinfection, soil amendments, hydroponics and soilless growing systems, soil solarization, grafting, biological and chemical control and use of natural compounds.
Grafting technology plays an important role in the management of infected vegetables with soil-borne pathogens because it can be quickly deployed without causing significant changes in farming operations.
Despite some disadvantages such as additional cost and physiological disorders due to incompatibility between rootstocks and scions, management of soil-borne diseases using grafted seedlings is considered one of the most important alternatives to chemical controlling of soil pathogens for vegetable crops.
The presented study was developed at HORTING Institute for evaluation the different healing environment parameters of grafted seedlings and for identification of efficient healing-room microclimate conditions and management strategies.
Experiments were conducted in 4 different healing enclosures.
Different environmental conditions were achieved in each one by varying the air relative humidity, the intensity of thermal radiation and the seedlings density.
After grafting, the plants were placed for 7 days in the healing tunnels and evaluated by survival rates.
For each case, specific parameters of the microclimate factors like temperature, relative humidity, CO2 concentration, intensity of light radiation, both inside and outside the tunnels, were measured.
The obtained results were analyzed and interpreted in order to develop strategies for the management of the microclimate factors in the healing rooms.
These strategies can expand the opportunities for growers to create their own grafted vegetables using inexpensive, appropriate-scale techniques.
