The simplest and easiest methods are morphological marker and growth response. The study aimed to develop early detection method of polyploidy occurrence in in vitro Tectona grandis after treated by antimitotic agent colchicine. Nodal segments were immersed at 0, 15, and 30 μM colchicines for 5 days, then cultured for 8 weeks. Observations on plantlet height, number of leaves and morphology were performed at 2, 4, and 6 weeks after planting. Colchicine had high significant effect on the height and significant effect on leaves number. High concentration colchicine inhibited shoot elongation and leaves growth, however it increased morphological changes. The planlets height of 0, 15, and 30 μM of colchicine treatment was 4.14; 3.82; 3.12 cm; while the number of leaves as much as 8.72; 8.4, and 7.5. Colchicine led to increase in morphological changes at the levels 0, 15, 30 μM were 26,60%; 46.66%; and 93.33%. Changes caused by polyploidy differ from media.
