Abstract

This experiment was undertaken in the greenhouse of the Dept. of Plant Protection, College of Agriculture, Univ. of Baghdad. Rhizomes of Sorghum halepense was cut units pieces of 5 buds each. The rhizomes was depths (5,10,15,20) cm and four times exposure to oven microwave radiation(0,2,4,6, min) .The results showed the effect of microwave radiation to kill rhizome buds. It showed an increased killing tissue when exposure increased in time. The time 6 min gave lower mean of live bud (3.33%) as compared to control which was (51.11%). The live bud was increased when depth of planting increased. The depth 20 cm gave higher percentage of live bud (22.50%). The depth 5 cm gave lower level of live bud (17.78%). The time 6 min at the depth 5 cm gave no live bud. The treatment of 2 min exposure to microwave radiation showed an increase in the length of shoot (15.07% cm) an compared to the control treatment ( 3.26 cm).
