Influence of Soil Salinity on the Interaction between Tomato and Broomrape plant(Orobanche cernua)

다국어 초록 (Multilingual Abstract)

Tomato seedlings (20- days old) were transplanted to infested soil with Orobanche cernua and non-infested soils. All plants were maintained under 0, 25, 50 and 75 mM NaCl soil salinity levels throughout their growing period under greenhouse conditions. Plants grown in O.cernua infested soil infiltrated with 0, 25, and 50 mM NaCl solution for salinity showed significant reduction in their growth as well as their total soluble carbohydrate and protein contents in compared with those grown in non-infested soil. However, under 75 mM NaCl salinity level all plants showed similar growth values whether they were grown in O. cernua infested or non-infested soil. Starting at the fifth and through out the eighth week after transplantation there was a significant increase in plant height in the 0, 25 and 50 mM NaCl irrigated plants over other treatments.Irrigation with 50 mM NaCl significantly reduced the emergence of O. cernua (2/plant) and the number of attachments (4.4 attachments) on roots of tomato.Furthermore, irrigation with 75 mM NaCl resulted in complete elimination of O. cernua emergence.
