| 摘 要： | 为揭示野生马铃薯的耐冻性机理,对野生马铃薯幼苗的耐冻性和冷驯化能力与过氧化物酶同工酶间的关系进行了研究。结果表明:耐冻性越强的品系,POD酶带颜色越深、酶带宽度越宽;冷驯化能力越强的材料在冷驯化后酶带颜色越深,没有冷驯化能力的材料冷驯化后POD酶带颜色深浅不变。认为:S.acaule无性系材料的耐冻性和冷驯化能力与POD同工酶酶带的颜色的深浅、酶带的宽度有密切关系;冷驯化能力的高低主要与冷驯化后酶带颜色深浅有关。 |

| Abstract: | The relationship between freeze tolerance and cold domestication ability of wild potato seedlings and POD isoenzyme was studied to provide the theoretical basis for revealing the freeze tolerance mechanism of wild potato lines.The results showed that the color and width of POD isoenzyme band increased with the increase of freeze tolerance ability of potato lines,the POD isoenzyme band color of potato lines with strong cold domestication ability became darker after cold domestication and the POD isoenzyme ba... |
