| Abstract | ||||
| Eight lectins, four of which were used in pure forms, i.e. lectins of white bean seeds, red bean (Adzuki) seeds, pea seeds and lentil seeds. The other four were used in crude forms for the first time, i.e. lectins of white bean seeds, soybean seeds, moringa seeds and orchid tree seeds. All plant lectins tested in vitro against the growth of three fungi that cause strawberry fruit-rot, i.e. Botrytis cinerea, Corynespora cassiicola and Alternaria alternata. The crude lectin exhibited high ability to inhibit radialgrowth of these fungi compared with the pure lectin, this may be due to the presence of other effective compounds besides lectins in the extract. There was congruence in the general effect of both tested crude and pure lectins on fungal growth, where Botrytis growth was the most affected by any used lectin. Moringa crude lectin was high efficient in inhibiting the radial growths with 80.00%, 71.33% and 53.00%, respectively. Postharvest spraying of strawberry fruits with crude lectins succeeded in reducing soft-rot severity compared to control under laboratory conditions outside refrigerators. Fungal treating in vitro with crude lectins was consistent with postharvest fruit treating, where moringa crude lectin showed high soft-rot inhibition efficiency (70.40, 66.28 and 30.93%). The results indicated possibility of exploiting crude plant lectins to discourage postharvest fruit-rot and it is tempting to repeat the experiment on plants in the greenhouse and then in the field if the necessary quantities of lectins are available when lectin production gene is transferred to a fast-developing microorganism. | ||||
