不同小麦基因型耐铝性的差异及筛选方法的研究
Differences of aluminum tolerance on wheat genotypes and its screening techniques
摘要
Abstract
Large-volume solution culture, rapid screening with soil in petridishes and small-pot soil test were used to screen for aluminum tolerance on wheat. Of the tested 24 wheat genotypes, there were significant differences of aluminum tolerance. Significant correlation was observed among screening criteria in wheat genotypes by three screening methods employed. In the tested parameters, relative root length (RRL) had the greatest variation, relative root weight (RRW) the second, and relative shoot length (RSL) and relative shoot weight (RSW) the last within wheat genotypes indicated by standard deviation (SD), coefficient of variation (CV) and distribution of data. These results implied that RRL and RRW could be sensitive and reliable screening criteria for differentiating aluminum tolerance in wheat genotypes, whereas RSL and RSW might be lower sensitive and reliable selection criteria. The three screening techniques developed in this study are superior to the conventional methods such as small- volume solution culture, pot experiment and field experiment which could be hardly used in the screening for a large number of genotypes because of their time and labor consumption. These three techniques are characterized by their convenience for operation, easy control of conditions, reliability and high screening effiency for a large number of genotypes in term of time and labor costs.关键词
