Effect of heat stress at anthesis on yield formation in winter wheat

Original language description

Heat stress around anthesis is considered to have an increasing impact on wheat yield under the ongoing climatenchange. However, the effect of high temperatures and their duration on formation of individual yield parameters isnstill little understood. Within this study, the effect of high temperatures applied during anthesis for 3 and 7 days onnyield formation parameters was analysed. The study was conducted in growth chambers under four temperaturenregimes (daily temperature maxima 26, 32, 35 and 38°C). In the periods preceding and following heat stress regimesnthe plants were cultivated under ambient weather conditions. The number of grains per spike was reduced underntemperatures ≥ 35°C in cv. Bohemia and ≥ 38°C in cv. Tobak. This resulted in a similar response of spike productivity.nThousand grain weight showed no response to temperature regime in cv. Tobak, whereas in cv. Bohemia, a peaknresponse to temperature with maximum at 35°C was observed. The duration of heat stress had only little effect onnmost yield formation parameters.
