Effects of cell volume and transplant age in cell flat on growth and flowering after transplanting in Antirrhinum majus L. cv. Mangetsu and initial growth after transplanting in Matthiola incana R. Br. cv. White Dorse were studied. Seeds were sown in flats of two cell sizes (cylinders, 448 and 220; volume 6, 12 ml, respectively). At the same time each species Were directly sown into wooden containers (38880 ml). The plants in cells were transplanted 32, 37, 42, 47, 52 days old after sowing in A. majus and l8, 25, 32, 39 days old in M. incana. The plants having formed root-balls could be found at 42 days and 47 days after sowing in cell volume of 6 ml and 12 ml respectively in A. majus, and at 25 days and 32 days after sowing in cell volume of 6 ml and 12 ml respectively in M. incana. In both species shoot dry weight, root dry weight, stem length, node number and total leaf area were increased with increases in cell volume or transplant age. In A. majus flowering was delayed with increases in transplant age, especially in cell volume of 6 ml. Cut flower quality suffered markedly with increases in transplant age. Node number was affected by cell volume but not by transplant age. In M. incana the growth 4 weeks after transplanting of plants grown for 25 days in cell volume of 12 ml showed little difference compared with that of plants grown in the wooden container. The results showed that for cell transplant production in both species, transplanting before 10 days formed root-balls using cell volume of 12ml was optimal. Our investigation suggests that the suitable transplant age for work efficiency of transplanting may differ considerably from that for plant growth in both species
