Morphological and anatomical studies of grafting cucumber onto three different wild rootstocks grown under salinity in Nutrient Film Technique system.

This is the second in a series of papers to study the response of cucumber grafted onto three different wild rootstocks namely; Lagnaria sicenaria, Luffa acutangula, and Cucurbita maxima ? Cucurbita moshata grown under Nutrient Film Technique (NFT) system with three salt concentrations (1.7, 2.9 and 4.2 dS/m) of morphological characters and anatomical structure during two successive seasons at the Station of Solar Energy Department of National Research Center, Giza, Egypt. The results of morphological and anatomical features revealed that grafting cucumber onto rootstock Cucurbita maxima ? Cucurbita moshata under salt concentration 1.7 dS/m recorded higher values than their control (non-grafted) correspondent in most investigated characters. On the other hand, cucumber grafted onto rootstock Luffa acutangula under salt concentration of 4.2 dS/m recorded the lowest values for the same studied traits compared with the control.
