激光加电场处理对水稻相关生理生化参数的影响

Effects of Laser and Electric Field on Related Physiological and Biochemical Parameters of Rice

探讨"三角大香糯"及激光加电场处理后的水稻"激三香糯"相关生理生化参数变化。测定叶绿素a与叶绿素b的含量、种子活力、赖氨酸含量、低温逆境下脯氨酸含量、可溶性糖含量、淀粉酶活性、过氧化氢酶活性、硝酸还原酶活性及呼吸速率。硝酸还原酶活性、过氧化氢酶活性、呼吸速率、赖氨酸含量等在处理前后变化不大;处理后可溶性糖含量、种子活力、叶绿素a与叶绿素b的含量有所提高,但淀粉酶活性下降。激光加电场诱变后,水稻的相关生理生化参数会发生相应的变化,有正向的,也有负向的。

To compare the related physiological and biochemical parameters of ＂Sanjiao fragrant glutinous rice from Yao＇an county＂ and its induced variety treated by laser and electric field.To measure the content of chlorophyll a,chlorophyll b,Lys,Pro under low temperature treatment and soluble sugar;the activity of amylase,catalase and nitrate reductase;seed vigor and respiratory rate.The activity of catalase and nitrate reductase,respiratory rate,and the content of Lys did not change so much;the activity of amylase declined;but the content of chlorophyll a,chlorophyll b,soluble sugar and seed vigor increased by laser and electric field treatment.The related physiological and biochemical parameters of ＂Sanjiao fragrant glutinous rice from Yao＇an county＂ and its induced variety treated by laser and electric field have changed,some of them increased,whereas some of them decreased.
