depression than GS fruit. From our anatomical study, we observed more severe cell collapse with BS fruit after chilling. However, RS fruit had a blemish-free appearance and had no damaged cells on examination by SEM ( Fig. 6 ). Although no CI symptoms were
resistance in cultivated watermelon was apparently lost during the many years of domestication and selection for desirable traits, including increased sugar content and red flesh ( Levi et al., 2001a , 2001b ). Conversely, various wild desert melons in the

, particularly, reduced the production of new conidia. UFGE 4033's responses against P. xanthii , therefore, are quite different from hypersensitive responses that are often conditioned by race-specific resistance genes and involve rapid collapse of host cells
mostly associated with a condition known as internal dry scale ( Fig. 3 ). Internal dry scale is a problem that occurs when one or more of the internal fleshy scales of the onion bulb collapse as a result of premature dieback of leaves during the growing
