Growth and Metabolism of Tomato Roots Grown in Tissue Cultures Held at Various Temperatures


The temperature of the root zone can influence tomato growth (3) and yield (1). This probably occurs by altering root sink strength, which, in turn, influences photosynthesis by affecting the RuBP carboxylase activation state (2). Our data further indicated that within certain limits of air temperature (17°–25°C) the optimal root zone temperature for seedling growth is between 27° and 32° (3, 7). However, prolonged growth at 29° resulted in reduced yield (1).
