试验地种群对比和生育特性的研究表明,不同羊草种群在叶色、穗型等形态特征上存在可遗传的明显变异。各种群间由于地理生态的不同,生育期也存在明显分化。灰叶羊草为早熟型,黄叶羊草为晚熟型。
The study on the population contrast and reproduction characteristics of the experimental land indicated that there was a significant genetic variation in the morphological characteristics of leaf color and panicle among different Leymus chinensis populations. Due to the different geographical populations of various groups, there are also significant differences in the growth period. Gray Leymus early-maturing type, yellow leaves Leymus late-maturing type.
