Comparison of the Metabolism of Nitrogen and Carbohydrate Compounds during Vernalization of Kohlrabi and Radish

球莖甘藍與蘿蔔之春化作用對氮素和碳水化物代謝比較

Abstracts


種子春化有效者(蘿蔔),由低溫處理而糖分增加。種子春化無效者(球莖甘藍)其低溫處理不能增加糖分。綠植物春化型(green plant vernaliation type)作物(如球莖甘藍),於植株完成基本營養生長後就與種子春化型(seed vernaliation type)作物(如蘿蔔)一樣,於低溫處理時糖類增加。 種子低溫有效者似含有較高之可移動性糖類,種子低溫無效者,似含不可動糖類。於生長過程中,可移動性塘類的逐漸增加而達到低溫感應。成株之糖類無論爲種子低溫感應型或綠植物春化型,都具含有較高之可移動性糖類,因此低溫條件下皆能完成其感應性。

Effective seed vernalization in seed vernalizing plants of radish was accompanied by an increase in sugar content during low temperature treatments. Green-plant vernalizing plants of kohlrabi showed no such sugar increase in seed vernalization treatment. Green-plant vernalizing plants of kohlrabi showed the same changes in sugar pattern as seed vernalizing types radish, but only after the plant had grown to a certain stage at which it was responsive to low temperature treatments. Seed vernalizing plants may contain high levels of mobilizing sugars in the seed while green-plant vernalizing types might contain obligate sugar only. A low temperature response from these crops was due to a gradual increase in mobilizing sugars during the growing process. Mature plants of seed vernalizing and green-plant vernalizing types contain higher levels of mobilizing sugars, making them more responsive to low temperature conditions.
