Abstract

In the course of gene bank research, problems frequently arise when valuable genetic materials have to be multiplied in an environment where the climatic conditions are quite different from those in its original habitat. In recently commenced experiments on the raising of emmer, the heading dates of two genotypes originating from different sources (MvGB 301 and MvGB 304) were investigated in a gradient growth chamber in the Martonvásár phytotron. This chamber allows precise information on the optimum temperature and light requirements of plants in different developmental stages to be obtained during the growth of a single generation. The data indicated that MvGB 301 headed considerably later than MvGB 304 at all temperature levels, but both varieties headed normally even at a constant very low temperature of 8 °C. It was found that the light intensity had no influence on the heading dates of the two varieties.
