The In Vivo propagation of Curcums (Z. spectabile) using stem cutting grown in different media was investigated at Central Mindanao University, Musuan, Bukidnon from June 15 to September 30, 2005. The study was conducted in a 3 x 4 factorial arrangement in a Completely Randomized Design replicate thrice with five samples per replicate. Three stem cutting sections: basal, middle and tip served as factor A and five growing media: garden soil, sand plus rice hulls, garden soil plus sand, and rice hulls plus sand as factor B.
Results revealed that tip stem section of curcums significantly exhibited the highest regeneration success (100%), the earliest to develop shoots (35.13 days) and roots (39.0 days) and had the most number of plants and suckers after 70 days. It also showed the tallest plants. The middle stem section ranked second while the basal ranked the last. Rice hulls significantly gave the highest regeneration success (88.89%) of curcum stem cuttings comparable to garden soil alone, (80.50%) and garden soil + sand (80.56%) and rice hulls plus sand (82.22%) while the sand had only 66.67%. Stem cuttings in rice hulls formed roots in 39.89 days and shoots in 41.11 days significantly early, developed the most number of 3.33 plants per section and 2.78 suckers per plant. Sand mixed with either garden soil or rice hulls gave similar results while garden soil alone ranked third and sand alone was last. The tip stem section of curcums grown in decomposed rice hulls provided a rapid method of in vivo propagation of curcums with about nine (9) plants section in seventy (70) days.
