EFFECT OF SOME SIMPLE TEMPERATURE PROGRAMS ON SPRING-WHEAT

B. Bretschneider-Herrmann
Six variations of temperature programs were used in a phytotron experiment with four spring-wheat varieties, from which one program with a seasonal pentade-curve and three temperatures per day was most similar to field conditions. The other programs were simplified by calculating statistical temperature-means from the first one.

It was found that the more simple programs by way of lower maximum temperatures had a positive influence on yield, mainly by 1000-grainweights and - with less significance - by the numbers of grains per ear.

The conclusion is drawn that in phtotron-experiments with springwheat rather simple temperature programs can be used without strong influences and development growth and yield.
