内容 Elongation of individual internodes and hypocotyl of Lycopersicon esculentum were investigated under eight treatments, obtained by combining one of two DIFs (photoperiod temperature-dark period temperature: +10 and -10℃) and one of three periods of growth (0-7, 8-15, and 16-22 days after the start of experiment). The temperatures used to create the DIFs were 20 and 30℃ in all treatments. The lengths of hypocotyl and all the internodes of tomato seedlings were measured at the start and end of each photoperiod and their daily elongation rates were calculated. The change in the elongation rates of hypocotyl and individual internodes with time closely matched a Gaussian curve. The peak height and the number of days to reach the peak varied from one internode to another. The stem length of the seedlings and the proportions of hypocotyl and individual internodes varied among the treatments. Results indicate that the length of hypocotyl and individual internodes of tomato can be controlled by changing DIF with time. This method could be applicable in the production of scions and rootstocks with controlled length of hypocotyl and individual internodes for efficient grafting operations of tomato and other fruit vegetable crops.
