영문 초록

The effects of a daylength has been emphasized on an early maturity as well as a maximum yield of wheat and barley cultivars. In order to see the effect, we examined any changes in physiological aspects during a stage of heading and a growth as well as an yield depending on a daylength. In general, as a daylength was shorter, culm length was longer. An early variety and an extremely early variety showing a shorter length, showed a shorter culm compared to medium-late variety showing medium-length variety. As a daylength was shorter, a heading occurred later. There was a big difference in the heading date among wheat and barley cultivars, and the naked barley showed a later heading date than the coverd barley. An extremely early variety showing an early heading was insensitive to a daylength and showed a high spring growth nature and had a property of short earliness. As a daylength was shorter, the number of spikes per a plant and the number of grains per a spike were increased but a weight of one thousand grains was decreased. There was a tendency of an increase in an yield of grains per a plant as a daylength was longer. Such an increase was more drastic in medium-late variety and extremely early variety. Growth habit, shortday response and earliness in narrow sense were originated from parents. This suggests that such traits be able to introduce into a variety through crossing.
