Response of Egyptian clover ecotypes to the non-thermal plasma radiation.

摘要

Field experiments were conducted at Atomic Energy Authority (AEA) Farm at Anshas, Egypt during 2009-2010 on multicut Egyptian clover cv. Gemmiza 1 (Gm) and single cut Fahl. Seeds were subjected to six treatments of non-thermal plasma pulse (pulsed atmospheric-pressure plasma jet [APPJ] apparatus). The plasma radiation (ozone, UV, visible light) was injected into the seed samples at different varying durations (number of pulses). Treatments were 1, 3, 5, 7, 9, and 11 pulses and non-treated control. The results revealed prominent effect of application of non-thermal plasma technique on morphological characters as well as fresh and dry yield on both cultivars. The highest values of dry and fresh yields were 10.0 and 63.0 t/fed (fed; Feddan=4200 m2) under 9 pulse. The 7 pulse treatment gave the highest values for Fahl dry and fresh matter 21.3 and 104.6 gram/10 plants respectively.
