High temperatures especially in greenhouses work on stress plants, this stress and damage increased in the presence of pathogenic soil fungi. Rhizoctonia solani is consider as an endemic fungus in the soil and causes significant problems for horticultural crops in greenhouses. This study was conducted to compare between cucumber and snake cucumber in terms of infection of R.solani and the impact of high temperatures where it was studied and compared the speed of germination, germination rate, seedling death and infection severity. The results showed that the cucumber was superior to snake cucumber at the rate of germination, where the seedling emergence was 62 hours after planting, while the seedling emergence for snake cucumber was 89 hours after planting. As for the germination percentage in soil contaminated with R.solani of cucumber and snake cucumber, were 40% and 26.66%, respectively. For the seedling death results were 33% and 25% in cucumber and snake cucumber plants respectively. Growth parameters were measured. The results showed that there were significant differences between them in growth parameters.
