Three hybrids of American cucumber were studied, they are Lot number EM285 labelednumber 1, Hybrid tocaeen F1 labeled number 2, Hybrid super green F1 labeled number 3. Theseeds of these hybrids were exposure to four frequencies of electric current 0,1,2 and 2.5 Am for5 minutes and 4 periods of ultra violate rays UV at 254 nm. For 0,30,60 and 90 second. Thesterilized seeds were cultured in MS medium. After 3 weeks apical meristems of seedling wereexcise and cultured in new MS medium and of 5 weeks shoot systems were taken to study theelement content nitrogen, phosphorous, potassium, calcium and magnesium in addition toestimate protein percentage. The results showed that hybrid 3 had a significant increase ofelement contents and protein percentage compared with hybrid1 and 2.The interactions betweenhybrid3 and 90 sec. UV exposure showed the highest content of calcium element reached 2.73mg.gm-1 with an increase of 184.37%compared with the control. The interaction between 2.5 Amand 90 sec. UV exposure showed the highest rate of protein reached 15.5%with significantdifferences of all interactions.
