通过转基因技术在草坪草改良中应用的介绍 ,得出 :采用现代基因工程来改良草坪草有巨大的商业潜力 ,草坪植物的组织培养和再生系统的建立为DNA的直接转移和农杆菌介导的转化提供了条件 ;遗传修饰的草坪草改善了其抗旱、抗高 (低 )温、抗病、抗除草剂和耐践踏的特性 ;携带异戊烯基转移酶基因的草坪草表现出分蘖力加强 ,严冬绿期延长 ;在期望利益的同时 ,应注意评估转基因草坪的生物安全性问题。
The results showed that:(1)Cd2+ stress had a significant effect on tillering ability,plant height,accumulating amount of dry matters,composing factors of yield and physiological activity of leaves;(2)The sensitive stage to Cd2+ stress was the stage before flowering,and at flowering stage,Cd2+ stress had less effect.
以扬稻6号和武运粳7号为材料进行盆栽实验,研究了Cd胁迫对水稻植株生长的影响,结果表明:(1)Cd胁迫对水稻植株的分蘖力、株高、植株干物质的积累量、产量构成因素以及叶片的生理活性等都有显著的影响;(2)Cd胁迫对水稻植株的分蘖、株高和植株干物质的积累量的影响均为植株较幼嫩时影响较大,而对开花期的分蘖成穗率、株高和植株干物质的积累量影响不大,反映了水稻植株在开花期具有较好的耐镉性;(3)对产量构成因素的影响为每穗粒数受影响最大,说明Cd胁迫抑制了穗分化;(4)Cd处理使分蘖末期水稻叶片电导率、丙二醛含量、脯氨酸含量和可溶性蛋白含量都上升了,而叶片的光合速率下降了,反映了水稻叶片在分蘖末期受Cd胁迫后,膜系统受到了伤害,而脯氨酸含量的上升则反映了水稻叶片同时也表现出了一定的耐Cd性。
