소맥에 있어서 온도 및 일장변화에 따른 생육 및 수량의 품종간 차이
Varietal Differences of the Yield and Growth Characteristics under the Different Temperature and Photoperiod Conditions in Winter Wheat
초록
소맥에 있어서 온도 및 일장변화에 따른 생육 및 수량의 품종간 차이를 구명하기 위하여 장광 등 8개품종을 공시하여 온도 2
Eight winter wheat varieties were tested to study the varietal differences on yield and the other characteristics at four different treatments with two different photoperiod and two different temperature levels. In heading date, Changkwang and Parker exhibited the moot sensitive responses to short day length, but Yecora 70. Suweon 169 and Bezostaya were insensitive in general. Culm length was greatly increased at short day length in Bezootaya while Yukseong 3 expressed same responses under low temperature condition. However, little variation of culm length was observed in Yecora 70 regardless the day length. Blueboy, Changkwang and Yecora 70 exhibited the minimal variations in culm length due to the temperature treatment. High yieldings were produced in Blueboy, Suweon 169 and Parker under short day condition, but Parker, Yecora 70. Yukseong 3 and Study produced high yields due to the influences of low temperature. Yield increase was primarily due to the increased number of spikes per plant and number of spikes per plant and 1, 000 grain weight under the low temperature conditions.
