Influence of tuber cutting size and plant growth regulators on growth and development of Caladium ‘Candidum’

Abstract

The result showed that the 1 cm of tuber cutting size was higher significant differed in the days to sprouting, tuber size, plant height, canopy width, and the number of leaves than the 0.5 cm of tuber cutting size. Besides, IBA at 150 ppm was higher significantly differed in the average survival rate, days to sprouting, tuber size, plant height, canopy width, and number of leaves than the others. The interaction between the tuber size at 1 cm and IBA at 150 ppm gave the highest days to sprouting, plant height, canopy width, and the number of leaves. Therefore, the Caladium ‘Candidum’ was cut at 1 cm size and soaked in 150 ppm of IBA that appropriated to induce growth after cutting within four months.
