The effect of grafting on growth and early production of cucumbers at low temperature

Plants of several varieties and breeding lines of cucumber (C u c u m i s s a t i v u s L.), grown at air temperatures of 20°C days and either 12°C or 7°C nights with soil temperature ranging from 14–22°C, grew faster and gave higher early yields, when grafted onto C u c u r b i t a f i c i f o l i a L. root-stock. More than half of the ungrafted plants died following transplanting in soil of 14–16°C, whereas all grafted plants survived. Grafting increased early yield by maximally 200&Eth;
