干旱脅迫對水稻幼苗脯氨酸含量的影響 在實驗室沙培條件下,分別測定了水稻品種金優(yōu)117幼苗在停止?jié)菜蟮谒奶臁⒌谖逄、第六天、第七天和第八天幼苗中脯氨酸的含量。?jīng)實驗表明,實驗組在干旱處理的五天內(nèi),水稻幼苗內(nèi)的脯氨酸含量有所上升,在第6天時,脯氨酸含量快速增加,隨后增速減慢,趨于穩(wěn)定。而對照組正常條件下水稻幼苗內(nèi)的脯氨酸含量較低且無明顯變化。由此可見,干旱脅迫下脯氨酸含量累積是水稻適應干旱條件的一種生理反應。 關鍵詞:干旱脅迫;水稻;脯氨酸 時間緊迫,謝謝大家了~~ [ Last edited by 唐君麗 on 2012-6-5 at 21:21 ] |

Effect of Drought Stress on proline content of rice seedlings The proline contents of rice seedlings of Jinyou 117 were measured at 4, 5, 6, 7 and 8 days after stopping watering under laboratory sand culture conditions. The results showed that the proline contents of rice seedlings increased after drought stress and reached their peaks at six days, and their growth rates subsequently slowed down and became stabile gradually. Whereas, without drought stress, the proline contents of rice seedlings were at low level and changed insignificantly throughout the observed time. Therefore, the accumulation of proline of rice seedlings under drought stress may be a physiological response to adaptation of drought condition. 【Key words】 Drought Stress; Rice; Proline |
| Drought effects of stress on PROLINE content in rice seedlingUnder conditions of sand cultured in the laboratory, determination of jinyou 117 stop watering the seedlings of rice varieties on the fourth day, fifth day, sixth day, seventh day, eighth day PROLINE content in seedlings. Experiments show that within five days of the experimental groups in dry processing, PROLINE content in rice seedling has increased, the 6th day, rapid increase of PROLINE content, then growth slows down, to stabilize. And control groups in rice seedlings under normal conditions of low PROLINE content and no noticeable changes. We can see that under drought stress accumulation of PROLINE content is adapted to the arid condition of a physiological response of rice.Keywords: drought stress, and rice; PROLINE |
