| Abstract: |
The reaction of six different local and introduced varieties of broad bean (Vlcia faba L.) towards Stenphylium botryosuim showed that there was no source of high-resistance within the studied varieties. All local varieties and introduced ones were subjected to infection. Generally, local varieties were more susceptible than the introduced ones. There was a positive correlation between percentage of penetrated stomata and susceptibility. Examination of stomatal apertures revealed that there was an apparent relationship between reaction to infection and stomatal pore widths. Relatively resistant varieties had a high frequency of narrow pores, whereas susceptible ones almost had wider stomata. However, both relatively resistant and susceptible varieties had similar pore lengths, thus indicating no correlation between stomatal pore length and disease reaction. |
