1. Hyphae were usually observed only in the epidermis and the collenchyma of the cortex, and in outer layer of the cortex of the untreated resistant squash hypocotyls. In the hypocotyls treated with concentrations from 10^<-3> to 10^<-7>M NaDEDC, hyphal spread showed throughout the sections including the pith cavity. 2. Hyphae invaded into the untreated resistant hypocotyls as well as those treated with 10^<-6> or 10^<-7>M NaDEDC were morphologically changed as evidenced by the swellings and curlings of the tips. There were few further extension or entanglement of hyphae in these hypocotyls. Extended and tangled hyphae were commonly observed in the hypocotyls treated with 10^<-3> to 10^<-4> M, but rarely suppressed. In hypocotyls treated with 10^<-5>M NaDEDC, all types of invading hyphae were observed.
