【 摘 要 】

Productivity of garlic from Doulu cultivar is still considered low and has not yet been able to fulfill local needs, especially in North-Sumatera. Meanwhile, the public interest of local garlic was low due to its tiny size and high cost compared to imported garlic. The aim of this study was to determine the effect of colchicine concentration during immersion treatment towards physiological performance of Doulu cultivar. Experimental design used in this study was randomized block design with two factorials comprised of 20 combinations and three replications. The first factor was colchicine concentration (D): 0% (D0), 0.1% (D1), 0.2% (D2), and 0.3% (D3). The second factor was immersion durations: 0 (T0), 6 (T1), 12 (T2), 18 (T3), 24 (T4) hr. The results showed that control group exhibit higher value in terms of plant height, number of leaves, dry and fresh weight of bulbs compared to treatment groups. Concentration of 0% (control) within 12 hr of immersion duration (D0T2) showed the highest plant height of 22.38 cm, producing 5.05 leaves and dry weight of 1.57 g. The heaviest weight of fresh bulbs was observed from treatment group, in concentration 0.3% colchicine within 0 hr of immersion duration (D3T0) yielding 4.58 g.
