中文摘要 | 氮肥試驗於民國85年春季在台大農業試驗場進行,採四重複之裂區設計,以氮肥 為主區,族群為副區。結果顯示在台北及花蓮兩族群間,貯藏性蛋白質總量、zeins、Z1、Z2、 albumins、globulins及glutelins皆達顯著差異;在氮肥處理間貯藏性蛋白質總量、zeins、Z1、 glutelins上有顯著差異;氮肥與族群的交感則都不顯著。增加氮肥施用量會使zeins及glutelins 的濃度增加,而zeins的增加主要是增加了屬於19Kd及22Kd的Z1部份的濃度,而Z2則 沒有明顯的改變,但在高氮下會降低,亦即Z1/Z2比例增加;另外albumins及globulins在 三個氮肥等級下也沒有明顯差異。 氮肥處理中所採用的台北族群及花蓮族群,前者貯臟性蛋白質濃度大於後者。且兩族群 zeins及Z1對於氮肥的反應略有不同,台北族群zeins及Z1濃度在施用150kg/ha氮肥,即 增加至接近最大量;而花蓮族群直到施用300kg/ha的氮肥時達最大,顯示兩族群可能有差 異存在。 |
英文摘要 | Respones of seed storage protein to nitrogen application were investigated between Taipei and Hwalian populations. The amount of total storage proteins, zeins, Z1 and glutelins were also significantly different among treatments. There were no interaction between nitrogen fertilizer rates and population. Increase of nitrogen rate would increase the concentration of ziens and glutelins. Concentration of zeins were increased majorly by the increase of 19Kd and 22kD of Z1, and there were no change in Z2. The ratio of Z1/Z2 was increased under high nitrogen rates. In addition, albumins and globulins were not significantly different among three nitrogen fertilizer application rates. Concentration of storage proteins in Taipei population were higher than that in Hwalian population. The responses to nitrogen, zeins and Z1 were different between two populations. Concentrations of zeins and Z1 in Taipei population increased to a maximum when the applied nitrogen rate reached 150 kg/ha, but concentration of zeins and Z1 in Hwalian population reached their maximum until nitrogen rate reached 300 kg/ha. |
