| Abstract | ||
| Three American cucumber ( Cucumis sativus L.) hybrids namely Lot Number (EM 285), labeled number 1, Hybrid super Green F1, labeled number 2 and Hybrid Top Caeen F1, labeled number 3 were tested Seeds of these hybrids were exposed to four frequencies of electric current (0,1,2 or 2.5 ) amber(Am.) for 5 minutes and four periods of exposure for ultra violate rays (UV) at 224 nanometer (nm) for (0,30,60 and 90) second. The treated seeds were sown on 2010 in open field that prepared and fertilized. with recommended fertilizers. The effect of electric current Am and UV on the production of these hybrids was studied. Flowers number/plant were recorded after 35 days of sowing, length , diameter and weight of fruit were recorded after 46 days of sowing. Results showed significant differences between the hybrids in the studied parameters. Hybrid 3 showed a significant increase compared with hybrids 1 and 2 since it gave the highest number of flowers (19.97 flower. Plant-1), tallest fruit length and diameter of fruit (14.09 and 7.93 cm.fruit-1 respectively) and highest fruit weight (46.97 g.fruit-1 ). While hybrid 2 gave 16.72 flower.plant-1, 10.35 cm.fruit-1,5.72 cm.fruit-1 (length and diameter of fruit respectively ) and 30.2 g.fruit-1.The results also indicated a significant interaction between electric current and UV in all studied parameters. The 2 Am frequency and 60 sec of UV exposure gave highest flowers number (24.09 flower .plant-1 ) with an increase 85.16% compared with 2.5 Am frequency and 90 sec. of UV exposure. Results also showed a significant interaction between hybrids, electric current and UV. Hybrid 3 treated with 2 Am and 60 sec exposure gave highest fruit weight (86.33g.fruit-1) with a significant increase for all interactions. | ||
