查询词典 hypothetical population

The objectives of the research were to screen molecular markers of sorghum resistant gene to the physiological strain No.3 of head smut with SSR. Bulked Segregation Analysis was applied in the study. Two segregation populations, restorer line population R population 2381R/Aisi and maintain line population Tx622B/7050B, were used in the research. The amplification bands of 94 pairs primers from 109 ones were clear and stable.

We will introduce some definitions in the Mathematics Ecology and the mathematical theories and methods. Methods for studding the population ecology or the more ordinary ecology are by setting up the mathematical modelings. We will give the examples of the single population models and the population with interaction models.

Result It was confirmed as a reasonable population when the total stem number of wheat in reviving stage was lower than the mature spike number, the shuttle-shaped plant form at the stage of maximal population, and the leaf area coefficient in flowering stage was 4. Soil fertility had significant influence on the growth of wheat stems and leaves at early stage and had certain influence at middle-late stage. Density influenced the growth of stems and leaves before the formation of the largest population, while it had little effect after flowering.

结果］冬小麦起身期的总茎数略低于成穗数，群体最大时期株型呈现梭形，开花期叶面积系数为4是较为合理的冠层结构；土壤肥力对小麦前期的茎、叶生长影响显著，在中后期也有一定的影响；密度则在形成最大群体前影响茎叶的生长，到小麦开花后影响不明显。
