摘要/Abstract

摘要： 野大麦无性系分蘖株由3个龄级组成,为明显的增长型年龄结构,1龄级蘖在无性系生殖生长中占绝对优势.分蘖株龄级越高,其数量增长速率越小,对无性系物质积累的贡献越小,1、2龄级分蘖株数量和生物量均随着无性系丛径和总蘖数的增加而增长,3龄级蘖与总蘖数间呈直线正相关.平均单蘖生产力随着龄级增加而下降.生殖蘖平均单蘖重具有相对稳定性.无性系中1龄级蘖平均单蘖重体现出一定的密度调节作用.无性系潜在种群也为明显的增长型年龄结构,营养蘖产生芽的数量远远多于生殖蘖,3个龄级营养蘖芽和生殖蘖芽与丛径和总蘖数间均呈正相关关系.

Abstract: The tillers of Hordeum brevisulatum clone have a significantly expanding age structure, which includes three age classes. The 1st age class tillers are absolutely dominant in the reproductive growth of the clone. The older the tillers, the smaller the rate of quantitative increase, and the less the accumulative nutrients are. The quantity and biomass of the 1st and 2nd age classes increase with the size and the tiller number of the clone, while the 3rd age class tillers are positively linearly interrelated to the total tillers of the clone. The mean weight per tiller decreases with the age class increased. The mean weight per reproductive tiller is relatively constant among three age classes, and that of the 1st tillers of clone has a negative respondence to the density of tiller. The age structure of the potential population of clone is also of an obviously expanding type. The buds on the vegetative tillers are always more than those on the reproductive tillers. The buds on the vegetative or reproductive tillers of every age class are all positively interrelated to the size and the total tillers of clone.
