大小麥 收量構成要素에 關與하는 몇가지 形質의 硏究 Ⅰ. 耐倒伏性의 品種間 差異

Studies on Several Characteristics Related to Yield Components in Winter Wheat and Barley Varieties Ⅰ. Varietal Differences to Lodging Resistance in Barley

耐倒伏性에 關與하는, 諸形質의 品種間差異를 檢討코저 標準肥區 多肥區를 두어 形態的 物理的特性을 檢討하였다. 1. 形態的 物理的特性의 品種間 差異를 檢討하여 表 10에서 耐倒伏性別 品種群을 分類하였다. 2. 耐倒伏性의 檢定에 있어서 窒素肥料만을 增施함이 倒伏과 相關이 높으며 判定이 容易하다. 3. 耐倒伏性의 判定은 어느한 特性調査만으로는 判定하기 어렵다고 본다.

In order to investigate the varietal differences on characteristics concerned with lodging resistances, 9 barley varieties were tested in standard and double nitrogen fertilizer applied plots, and morphological and physical characteristics were measured. All tested varieties were classified into 5 types in lodging resistance. Therefore, it is considered that double nitrogen applied condition is efficient enough to determine the degree of lodging resistance.
