摘    要:通过不同供钾水平的土培试验,研究了钾高效基因型大麦Sandrime和钾低效基因型大麦ACWestech对钾素的吸收、积累和分配特性。结果表明:在各生育期,钾高效基因型Sandrime株高和生物量均大于钾低效基因型AC Westech,根冠比小于低效基因型,但钾低效基因型缺钾症状比高效基因型严重;不同钾效率基因型大麦各器...

关 键 词:大麦  基因型  含钾量  钾积累量  分配比例

Abstract:In this study,a pot experiment with different levels of potassium(K) was conducted to reveal the differences in K absorption,accumulation and distribution between K-efficient barley genotype(Sandrime) and K-inefficient genotype(AC Westech).Results showed that,during the whole growth period,K-efficient barley genotype has the higher plant height and biomass,but lower root-shoot ratio than K-inefficient barley genotype,and the K-deficiency symptom of(AC Westech) was more serious than Sandrime.The content of K...
Keywords:barley  genotype  K content  K accumulation  distribution ratio
