Response and compatibility of some faba bean (Vicia faba L.) cultivars to inoculation with salinity-tolerant rhizobial strain under high salinity conditions [electronic resource].

Includes reference.

Pots experiments were carried out at Dept. of Agric Botany, Fac, of Agric. Kafr El-Sheihk, Tanta Univ., Egypt during the winter season of 2004/2005 to study the response and compatibility of four faba bean cultivars to nodulation with the the Rhizobium leguminosarum biovar. viciae rhizobial strain (EI) previously isolated, identified and adapted against the high concentration of NaCI. In this study, seed treatment with Peat-based preparation of (El) at the time of planting in sandy soil irrigated with 200 roM NaCI concentration exhibited significant differences in the plant growth and nodulation parameters as well as crude protein % of dry seeds between the cultivars under study. The response of cultivars Giza Blanca and Giza 957 to rhizobia! nodulation (464.67 and 394.33 nodules/plant, respectively) was more compatible with strain (El) than Sakha 1 and Reina Mora (50.33 and 39.33/plant, respectively). Success in nodulation resulted in significant improvements in both the plant growth and the dry seed crude protein % parameters as well as the total microbial counts in the rhizosphere of the growing plants. . The absence of nodules on the non-inoculated plants revealed the necessity of using the effective and salinity-tolerant rhizobial strain (EI) to inoculate faba been under saline conditions.
