水稻幼苗的生長發育及觸媒酶活性受光照及缺氧條件影響之情形作了初步之觀察研究。光照對上胚軸的生長並沒有顯著的影響,但在光照及缺氧條件同時存在下則對生長之抑制作用相當明顯。表示此兩種環境因子有相互的加強作用。觸媒酶活性隨著幼苗之生長而增高,二者具有相當高的正相關。缺氧條件對酶活性有明顯的抑制作用,尤其是台中秈3號幼苗缺氧下的酶活性特別低,顯示此品種對缺氧條件之抵抗力比台中65號差。台中秈3號酶抽取液可分離五條異構酶帶,根據其酶帶數目及活性比例分佈顯示其為兩類酶次體所組成。向陽極移動快速之酶次體為受光照所誘導者。台中65號酶抽取液只含四條異構酶帶,其分子結構,活性比例分佈以及對缺氧條件之抵抗性等都有加以討論。
The effect of light and the anaerobic condition on the basis of morphogenesis of rice seedlings was investigated. The length of epicotyl was not affected significantly by light, but the inhibition become dominant when the seedlings was treated simulteniously by light and anaerobic condition. It was indicated that both factors had the synergy effect on the growth of seedling. Catalase activity increased with the growth of seedlings. The enzyme activity and the length of epicotyl showed very high positive correlation. Catalase activity was inhibited effectively by the anaerobic condition, especially in the seedlings of Taichung San 3 which appeared more sensitivity. Enzyme extracted from the epicotyl of Taichung San 3 could be separated into five isozymes. According to the number of isozymes and the distribution of the enzyme activity, it was concluded that the molecular nature of the enzyme should be tetrameric constitution which was derivated from two type of subunits. The subunit which showed higher mobility to the anode was induced by light. Unexpectively only four isozymes was observed from the extract of Taichung 65 epicotyls. The molecular constitution, activity of the isozymes and the resistance to the anaerobic condition were discussed.
