One treatment comprised a rapid increase to 40°C, which was then maintained for 4 h on 5 successive days, giving a total of 15 degree-days of stress (15 DD/40°C). The second treatment comprised 5 days of stepwise increase in daily maximum temperature to 40°C, giving a total of 45 degree-days above control conditions (45 DD/stepped). The 15 DD/40°C heat treatment accelerated plant maturity and resulted in drastically decreased seed weight, and therefore yield, compared with the control, whereas the 45 DD/stepped treatment had much less effect on the 3 lines, particularly Oscar. Oil concentration of the seed was reduced following the 15 DD/40. The second treatment comprised 5 days of stepwise increase in daily maximum temperature to 40al of 15 degree-days of stress (15 DD/40s.

One treatment comprised a rapid increase to 40°C, which was then maintained for 4 h on 5 successive days, giving a total of 15 degree-days of stress (15 DD/40°C). The second treatment comprised 5 days of stepwise increase in daily maximum temperature to 40°C, giving a total of 45 degree-days above control conditions (45 DD/stepped). The 15 DD/40°C heat treatment accelerated plant maturity and resulted in drastically decreased seed weight, and therefore yield, compared with the control, whereas the 45 DD/stepped treatment had much less effect on the 3 lines, particularly Oscar. Oil concentration of the seed was reduced following the 15 DD/40.
