| 摘 要： | 以赤峰特选甜椒为对照(CK),研究低温弱光胁迫下不同砧木幼苗生理生化特性、光合速率及光化学效率的变化.结果表明,低温弱光处理后,供试砧木幼苗的电解质渗漏率和MDA含量低于CK,根系活力、Pn、Fv/Fm及保护酶活性多高于CK.综合比较认为,供试砧木材料中,卫士的耐冷性最强,部野丁和金富早其次,铁木砧和骄珍最弱,但它们均比CK的耐冷性强. |

| Abstract: | Changes of physiological and biochemical characteristics,photosynthetic rate and photochemical efficiency of different sweet pepper rootstock seedlings under low temperature and light intensity were studied,with Chifengtexuan,a sweet pepper variety as control(CK).The electrolytic leakage and MDA content were lower in rootstock seedlings,the root activity,Pn,Fv/Fm and protective enzymes activity of rootstock seedlings were highter than those of the control.Comprehensive compared,Weishirepresent the highest tolerance to low temperature and light intensity,Buyeding and Jinfuzao next,and Tiemuzhen and Jiaozhen the weakest among the five rootstock varieties.All of them have higher tolerance than the control. |
| Keywords: | Sweet pepper Rootstock Low temperature Low light intensity Tolerance |
