Abstract


The experiment aims to observe the effect of mutagen concentration of sodium azide to the germination and seedling growth performance of upland rice varieties Jambek Rotan generation M-1 and the difference seedling growth of upland rice varieties Jambek Rotan on the generation of M-1 by application Sodium azide some mutagen concentration. The experiment was conducted in an area behind the Soil Laboratory , Faculty of Agriculture , University of Riau , from May to July 2015. Research arranged experimentally using a Completely Randomized Design (CRD), which consists of 5 treatments concentration of sodium azide (SA) , ie 0.0 mM SA , 0.5 mM SA, 1.0 mM SA, 1.5 mM SA and 2.0 mM SA and each treatment was replicated four times. Parameters observed were the percentage of live seedling , seedling height, number of leaves and the number of tillers. The results showed that the of sodium azide at a concentration of 2.0 mM produce the lowest percentage life seedling, but tended to produce the lower seedling height and the more number of tillers.
