Abstract :
?Induced Mutation of Caladium bicolor (W.ait) Vent. Using UV ray? has been
done at Genetic Laboratory and Plant Physiology Laboratory FMIPA USU Medan.
This research was aimed to study the effect of the interaction between UV ray
intensity and time exposure on the growth of the Caladium. The design used complete
factorial randomized design with 2 factors, that are UV light 4 levels : 0, 40, 50 and
60 Watt and the length of UV exposure with 4 levels : 1, 2 , 3 and 4 hours. The result
showed that the increasing of UV up to 60 Watt and time exposure 4 hours, caused the
decrease on height, length and width and number of leaves, the fresh and dry weight
of the plants, along with the increasing of the length of exposure. Mean while the
number of chlorophyll increase along with the increasing of the time exposure.
