Scion – Pumpkin (Interspecific hybrids)

Cucurbita maxima Duchesne x Cucurbita moschata Duchesne

The scion in combination with interspecific pumpkin hybrids (C. maxima x C. moschata) refers to cultivated varieties of cucurbits or cucumber grafted onto this rootstock to increase their resistance to soil-borne pathogens and environmental stress factors.

In the reference 19 varieties crop Cucurbita maxima Duchesne x Cucurbita moschata Duchesne, where this is mentioned in the description.

Interspecific pumpkin hybrids in the grafting system serve as a vigorous rootstock, providing resistance to Fusarium wilt, Verticillium wilt, Ascochyta blight, and Monosporascus. The use of these hybrids increases the scion's adaptability to soil salinity, as well as to extreme temperature regimes and moisture deficit.

The technical aspect of working with such a rootstock is determined by the structure of the hypocotyl, which is hollow and increases in volume as the seedling develops. To ensure successful tissue union and minimize the influence of the rootstock on fruit flavor, grafting is performed at early developmental stages, strictly synchronizing seed sowing dates to achieve identical stem diameters for both the scion and the rootstock.
