Abstract:
Microwave radiation effects depend on radiation frequency and exposure period. Generally, low microwave exposure has been successfully used as a positive effect on the accelerating seed germination, while a long exposure usually tends to reduce plant growth. Microwave irradiation could affect plant growth, development and seed germination. The objective of the study is to examine the effects of microwave radiation (low and medium) on seed germination of bean and maize. Various germination traits were estimated and monitored during the experiment at different time-points; 4, 7, and 10 days after sowing (DAS). Seeds of Maize and Bean were divided into two, each group containing three replicas of maize and bean seeds. The first group represents the untreated (unexposed) control and second group was irradiated with different exposure periods to microwave Panasonic(r) NN-N740 (Low and Medium for 1, 2, 3 and 4 minutes for both maize and beans). The length of maize and bean seeds increased during the trials germination days (5,7 and 10) compare to length recorded for control for exposed low and medium microwave radiation at time interval of 1, 2, 3 and 4 minutes respectively. The microwave radiation used in the present study promoted grains germination, accelerated seedling development and growth. The results obtained from this experiment emphasized the necessity of exposing maize and bean seeds to lowest time of microwave before sowing in seed beds to promote a high germinate and to produce uniform seedlings. The effects of different treatments were found to be stimulating the germination and seedling vigour of plants especially in power and exposure time treatments.
