• Factors related to the low survival of cucumber plants grafted onto pumpkin rootstocks using a newly developed grafting robot were determined. Horizontal-cut grafting (HCG), whereby hypocotyls of the scion and rootstock are cut at right angles and the cut surfaces are spliced, is used with a robot. The proportion of surviving grafted plants using HCG were compared with those using slant-cut grafting (SCG). Without cotyledons, proportion of surviving grafted plants was lower using HCG than using SCG, whereas the cut level at the hypocotyls had no effect. The proportion of surviving grafted plants was highest at a splicing pressure of 830g/cm^2. Pressed cut surface areas at more than 5.5 cm^2 increased the proportion of surviving grafted plants compared with 0 cm^2 (HCG) The proportion of surviving grafted plants and plant growth after transplanting increased with increasing area of cotyledons. These results suggest that low survival of cucumber plants grafted by horizontal-cut grafting is attributed to low pressure on the spliced cut surfaces and loss of cotyledons on the rootstock.
