Abstract
Bean plants grown in a controlled temperature glasshouse at high temperatures (33/28, 30/25, or 27/22 °C) during the period of seed development and maturation matured early and produced small seeds. The seeds were of lower vigour than those grown at 21/16 or 18/13 °C. The detrimental effect of high maturation temperatures was observed even on plants bearing well-developed seeds (yellow, fleshy-pod stage). Seeds matured at high temperatures were also more susceptible to deterioration with delay in harvest, and to mechanical damage. Heavy watering of plants with seed ready to harvest caused a reduction in seed vigour. For optimum quality bean seed, it appears essential that the seed develops and matures at cool temperatures, in a dry environment.
