以低海拔(567 m)人工种植的天山雪莲一年生植株为研究对象,从叶片数、叶长度、根长、单株鲜重等调查其生态表型,分析其生长规律,论述其生物学特性,以期为该种植物的保护及合理开发利用提供理论依据。结果表明:低海拔天山雪莲一年生植株生长特点为播种后至45 d之间生长缓慢,之后其生长速度加快,70 d后又缓慢生长;播种后覆盖草帘子,可提高人工种植的出苗率;其生长具有一定的耐旱性;一年生雪莲植株能刈割两次,刈割后大约20 d时,叶长度和叶片数基本能长至原来植株大小,但丛幅显著变小;刈割能促使其再生、避开高温天气及虫害大发生。

Other Abstract

To establish a rapid DNA extraction method for the screening of transgenic rice.[Method]The kit method and fast methodof two DNA extraction methods were compared,and were proved by Ta NADP - ME1 and Ta NADP-ME2 gene transgenic rice respectively.[Result]PCR was done by using the DNA which extracted by the rapid method as template,about 1 700 bp Ta NADP-ME2 gene and about 1 900bp Ta NADP-ME1 gene were obtained respectively,and the strips were clear and bright,comparing with the kit method showed no significantdifference.[Conclusion]The rapid DNA extraction method of this study is economic,simple and quick,suitable for the large transgenic samples detection.
