Influence of Soil Salinity on the Interaction between Tomato and Broomrape plant (Orobanche cernua)
Al-Khateeb, W.M.,Hameed, K.M.,Shibli, R.A. The Korean Society of Plant Pathology 2005 Plant Pathology Journal Vol.21 No.4
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 NaCI 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.

Effect of Salinity on Orobanche cernua Seed Germination
Al-Khateeb, W.M.,Hameed, K.M.,Shibli, R.A. The Korean Society of Plant Pathology 2003 Plant Pathology Journal Vol.19 No.3
Seeds of broomrape (Orobanche cernua) were exposed to 0, 25, 50, 75, and 100 mM NaCl solutions during their preconditioning period (14 days of moisture) under laboratory conditions and induced to germinate by synthetic germination stimulant (GR24). There was significant reduction in seed germination with increased salt concentration as shown in 35.2, 32.5, 23.6, 14.3, and 9.2% germination, respectively. Exposure of Orobanche cernua seeds to 0.0, 1.0, 1.25, and 1.5 M levels of NaCl for 9 hours resulted in 29.4, 21.3, 20.5, and 17.4% germination, respectively. Water preconditioned seeds showed Heavier protein profile bands of 6.5-14.2 KDa than those of dry seeds. Seeds treated with 0.75 M NaCl showed profile similar with that of water preconditioned ones, plus an extra band at 29-36 KDa. The protein profiles of 1.0 and 1.5 M NaCl treated seeds showed weaker bands with the absence of 29-36 KDa band.
