• The results indicate that : in both normal temperature and heat shock , the contents of mitochondrion proteins of sterile plants and control plants are significantly different ( p < 0 . 01 , n = 10 ) ; the differences of contents of mitochondrion proteins of sterile plants in the normal temperature and heat shock response are not significant , which mean that the expression of hsp70 gene is inhibited and the function of mitochondrion is disturbed
  01 ， n 10 ） ；而不育植株在常温和热激条件下线粒体蛋白含量差异不显著，说明转化株中hsp70基因的表达受到抑制，从而进一步扰乱了线粒体的功能，最终导致转化株雄性不育，表明hsp70反义cdna能够通过抑制hsp70基因的表达导致植物雄性不育。

• The paper summarized the research for the effects of different grazing intensity on grazing behaviour , grazing grass species and productivity of sheep in recent years , the result showed that : there was a negative correlation between the live weight gain per sheep and the grazing intensity , but there was positive correlation between the live weight gain per hectare and the grazing intensity ; feeding intake of sheep decreased when the grazing intensity become heavier ; there was not significant effect of different grazing intensity on sheep breeding indexes ; as long with the grazing intensity become heavier , the feeding time of sheep increased while resting and idling time decreased , but feeding intake per hundred mouths and daily intake reduced while intake velocity increased ; sheep feeding adaptability is relative ; the light grazing was beneficial to promote mutton quality , but mutton quantity and gross economy benefit was low
  摘要根据近几十年来放牧强度对绵羊放牧行为、采食植物组成和生产性能的影响进行了综述，得出以下结论：绵羊的个体增重与放牧率之间呈线性负相关，而公顷增重与放牧率之间呈正相关；绵羊的采食量随著放牧强度的加重而降低；放牧强度对母羊繁殖性能各指标影响差异不显著；随著放牧强度的加重，绵羊的采食时间增加，游走、反刍卧息时间减少；每百口采食量和日采食量减少，而采食速度增加；放牧绵羊的嗜食性是相对的；轻牧有利于提高肉的品质，但是产肉量低，总的经济效益不高。
