The infection process of Colletotrichum orbiculare on the leaves of susceptible and resistant cucumber cultivars were studied histologically. On both cultivars, conidia began to germinate 8 h after inoculation (hai) and formed appressoria. Then melanised appressoria formed penetration pegs at 10 hai. On the susceptible cultivar, infection vesicles formed within 24 hai and developed thick, […]

Infection Process of Sphaerotheca fuliginea on Host Cucumber and on host Wheat Leaves
The infection process of Sphaerotheca fuliginea into epidermal cells of host cucumber and nonhost wheat were studied histochemically. The percentages of germinated conidia had no significant difference on cucumber and wheat leaves at the pre-penetration stage. When S. fuliginea overcame the constitutive barriers of wheat leaf, papillae and hypersensitive reaction were induced to prevent the […]
