초록

Few studies have reported how temperature influences growth and development of succulents, including anthocyanin production, which could fetch better prices in the market, and understanding the factors influencing such pigments would benefit farmers. The present study investigated the effect of temperature (10°C, 20°C, and 30°C) on the growth, development, and anthocyanin concentrations in Echeveria agavoides and E. marcus. In E. agavoides, similar growth performance was observed at 10°C and 20°C based on plant height and diameter. However, subjecting the species to a high temperature of 30°C resulted in a decrease in plant height. In E. marcus, optimal growth performance was observed at 20°C. Different temperatures did not significantly affect succulent quality and color hues. Only L* values were significantly different among the Hunter’s Lab values. Similar results were observed following anthocyanin and image analyses, both of which were not significantly affected by temperature. However, an intense red pigment was observed at 20°C compared with the green pigment observed at 10°C and 30°C based on the image analysis. The results suggest that temperature influences growth, development, and anthocyanin content of Echeveria succulents, and 20°C could be the optimal temperature for the cultivation of the species.
