Effects of Cucumis and Cucurbita Rootstocks on Vegetative Traits, Yield and Quality in 'Tainan No. 1' Cucumber

'Tainan No.1' cucumber, an F1 hybrid, is powdery-mildew resistant and is, therefore, fit for greenhouse-culture. Soil-borne diseases in cucurbits have gained increasing importance with intensive cultivation of these crops. In the present experiment, cucumber cv. 'Tainan No. 1' was grafted onto two ischolar_mainstocks, viz., Cucumis and Cucurbita. Nongrafted cucumber plants were used as the Control. Results revealed that both kinds of grafted plants had similar graft-survival rate, and, better vegetative growth than non-grafted ones; however, between the two ischolar_mainstocks, grafted plants did not differ in vegetative growth or yield. Further, plants grafted on Cucumis had significant effect on fruit quality. In is therefore recommended that grafting procedure in cucumber greenhouse-culture can be practiced on Cucumis.
