Observations on growth and development rates of tomato seedlings


, : Observations on growth and development rates of tomato seedlings. Acta Horticulturae (32): 161-172

Throughout the year, except for 2 or 3 months in the winter, young tomato seedlings increased in weight by about 50% each day. Eventually their growth rate fell, but the time at which this fall began depended on their nutrient and water supplies and pot size. Differences in the duration of optimal growth caused very large differences in weight, e.g. plants weighed 20g 30 days from germination in poor conditions but 240g in improved conditions. Plants began to flower when they weighed 40-80 g.
