تأثير شدة مغنطة البذور وماء الري على سرعة ونسبة إنبات البذور والصفات الخضرية لنبات القطن Gossypium hirsutum ) (

Abstract

Factorial experiment was executed with two factors, intensity of magnation (control, 200 and 300 gauss), interval of exposure (5 and 15 minutes) using 4 replications with C R D in the Tech. Ins. Of Mosul to determine their effects on germination speed and percent cotton (Gossypium hirsutum) seeds in addition to vegetation properties. Magnetic intensity levels showed significant differences on all properties except wet root and the dry vegetation weight, while the factor (time of exposure) was not significant among the experiment but it's interaction with the other factor was. The control treatment was the best with germination percent as double as compared with the level 200 gauss with means of 72.5 and 36.5 respectively with the same aspect that germination speed followed with means of 0.894 and 0.477 respectively. All interactions were significant in this experiment.
