为了研究草地早熟禾无性系冬眠构件形态特征及生长规律,试验采用大样本随机挖取单个无性系,观测草地早熟禾种群分株构件的生长特征。结果表明:在生长季末期,草地早熟禾无性系冬眠构件是由冬眠苗和冬眠芽组成,其中冬眠苗平均为(65.15±34.84)个,冬眠芽为(7.35±4.15)个。草地早熟禾无性系冬眠苗数、冬眠芽数、冬眠苗生物量、冬眠芽生物量均随着丛径的增加呈幂函数异速生长。说明翌年的早熟禾无性系种群、苗库将远远大于芽库的贡献。 In order to study the morphological characteristics and growth pattern of blueberry clones of Kentucky bluegrass, a large sample was used to dig a single clone at random to observe the growth characteristics of the components of the blueberry. The results showed that at the end of the growing season, the components of the clonal dormant component of the blueberry were composed of the hibernation and the hibernation buds, with the average number of hibernation (65.15 ± 34.84) ​​and the number of hibernation buds (7.35 ± 4.15). The number of dormant seedlings, the number of dormant buds, the biomass of dormant seedlings, and the biomass of dormant buds of bluegrass in Kentucky bluegrass all increased with power function at different speeds. Explain the next year’s Poa clones clonal populations, seedlings will be far greater than bud pool contribution.
