Abstract : Powdery mildews are plant diseases caused by fungi, including Sphaerotheca fuliginea Poll. that attack melon (Cucumis melo L.) leaves. They cause a reduction in fruit production qualitatively and quantitatively through a decrease on leaves health. In this case, fungicide treatment in controlling the disease was not effective way. Another way to control powdery mildews is by planting melon cultivars that are resistant to the fungi. Plant resistance to Sphaerotheca fuliginea Poll. might have a relationship to leaf anatomical structure, especially to epidermis, a tissue that directly contact with outside environment. Therefore, the aim of this research was to characterize epidermal leaf structure of resistant and susceptible cultivars. Melon cultivars used in this study were two resistant cultivars (PI 371795 and PMAR), one susceptible cultivar (Action 434) and two other cultivars (Fresh 848 and Sakata 144) which are not known their characteristic to powdery mildews. The fifth leaves (counted from the cotyledon) were collected from melon plants which reached early generative development. Leaf epidermal slides were prepared semi permanently in glycerin medium. From this study, it was found that there were some morphological and anatomical differences on epidermal structure between the resistant and susceptible cultivars. Morphologically, the leaves of resistant cultivars have dendatus leaf edges, while the susceptible one has repandus leaf edges. Anatomically, the leaves of PI 371795 had upper epidermal cells with wavy edges, but not in the others. Both PI 371795 and PMAR 5 had irregular shape of lower epidermal cells with curved edges, while leaf epidermal cells from susceptible cultivar tended to have irregular polygonal upper and lower epidermal cells with straight edges and shorter non-glandular trichomes. PMAR 5 had long glandular trichomes. There was no significant difference between cultivars in the average of stomata number, the average of stomata index and trichome number on the upper epidermal tissue, while in term of the same parameters on the lower epidermal tissue had significant differences. In the lower epidermis, PI 371 and PMAR 5 had lower average of stomata number and stomata index compared to Action 434. PMAR 5 had higher number of trichomes than susceptible cultivar (Action 434). Meanwhile, Fresh 848 cultivar tends to have similar characters to resistant ones in terms of leaf edges, lower epidermal shape, stomata number and index. Sakata 144 had similar characters to those the susceptible one in terms on leaf edges, lower epidermal cells shape, stomata number and index, but not in trochome number. It may be assumed that first protection of melon against S. fuliginea Poll. is located on lower epidermal tissue.
