Coreana )和e californicus ( h californica )具有与赖草属leymus相同的nsxm染色体组，并把这两个物种组合到leymus中，使得hystrix的分类更为复杂。 - Until now , the definition of hystrix and its precise taxonomic rank are still under discussion . the main controversial is included the species of hystrix either in hystrix , or regard it as a part of elymus or leymus
关于hystrix属的界限和物种划分一直处在争议中，主要分歧是：将这些物种置于hystrix ，还是作为elymus的一部分以及还是放在leymus中。 - 5 . to assess the phylogenetic relationships among hystrix , leymus and psathyrostachys , two dna molecular markers rapd and issr were used . the results indicated that the level of genetic variation of three different genera is higher than species within the genus
Hystrix 、 l聊us及psathytostachys三个属11个种1变种共13份材料的l ； oyd和issr分析表明：属间存在较大的遗传多样性； l聊us和psathyffistachys属内种间的遗传变异较小。 - The objective of the present paper was to investigate the genome constitution of three species of hystrix and their taxonomic status from cytological and molecular data . by rapd and issr assay , the present study was to evaluate phylogenetic relationships among hystrix , leymus and psathyrostachys , and to compare the use of two molecular markers in the genus and species of triticeae
本研究( 1 )通过形态学特征比较、细胞学和繁育学资料，探讨三个hystrix物种的染色体组组成及亲缘关系； ( 2 )通过rapd分析和issr分析，探讨hystrix与leymus 、新麦草属psathyrostachys的属间亲缘关系； ( 3 )比较rapd和issr两种dna分子标记在hystrix及近缘属系统分类研究中的应用。 - The sowing and seedling raising experiments of castanopsis hystrix seed with different artificial treatments showed 1 - year - old c . hystrix seedling average height and average dbh with the treatments of hastening germination and cutting root were 22 . 0 % and 117 . 0 % higher than those without the root cutting treatment , respectively , the individual - tree lateral root number increased by 127 . 71 % , the afforested survival rate increased by 23 . 0 %
