Purdue University researchers have developed a set of propagation and production protocols that will help Indiana greenhouse growers bring a tropical plant into flower for spring sales.
Roberto G. Lopez, an assistant professor of horticulture, and Arianna P. Torres, a doctoral student in agricultural economics and a former graduate student under Lopez, determined the optimal light intensity, temperature and photoperiod for Tecoma stans, a flowering shrub with yellow, trumpetlike flowers. Their findings, based on seeds and seedlings grown under varying light and temperature conditions, were published in two papers in the journal HortScience.
