The tiller - nodes of 6 species of rhizome grass , including leymus chinensis , hemarthriajaponica , arundinella hirta , calamagrostis epigeios , c . rigidula , hordeum brevisubulatum in songnen plain , can live at best for 2 to 5 years , and do 2 to 4 propagating generations which is the same as the age class of tiller in number . the age structure of population is an increasing model which the young tiller is more than the old at quantity and biomass . during the whole growing season , the age spectrum varies for each species 松嫩平原,羊草、牛鞭草、野古草、拂子茅、硬拂子茅和野大麥等6種根莖型禾草種群的分蘗節最多可以存活2 5個年度,可以進行營養繁殖2 4個世代,分蘗株的齡級數與分蘗節營養繁殖的世代數相同,在種群分蘗株的數量和生物量上,生長季的各個時期均以幼齡分蘗株占較大比例,呈現為明顯的增長型年齡結構,各種類的年齡譜組成各異。

Bud is produced in both rhizome and tiller - node , rhizome can produce more buds than tiller - node on hordeum brevisubulatum , arundinella hirta , calamagrostis epigeios , c . rigidula and hierochloe glabra populations . both 1st age rhizome and tiller - node of 1st age tiller are mainly two contributors in importing of bud bank 根莖和分蘗節是芽的主要產生部位,牛鞭草、野古草、拂子茅、硬拂子茅和光稃茅香種群根莖的營養繁殖力比分蘗節強, 1齡根莖和1齡分蘗株分蘗節是芽庫輸入的主要貢獻者。

The bud bank is composed of 3 age classes bud on leymus chinensis , arundinella hirta and hordeum brevisubulatum populations , 2 age classes bud on hemarthria japonica , calamagrostis epigeios and c . rigidula populations . the age structure of bud is obviously an increasing model in all of 6 grass species 羊草、野古草和野大麥種群芽庫由3個齡級組成,牛鞭草、拂子茅和硬拂子茅種群由2個齡級組成, 6種禾草芽庫的年齡結構均為明顯的增長型。

In this thesis , hordeum brevisubulatum ( trinius ) link , which is one of the fine and important forage grass species in the north of china , is researched on its growth and development , physiological ecology and population ecology 本論文對野大麥( hordeumbrevisubularum ( trinius ) link )這一北方優良牧草在個體生長發育、生理生態以及種群生物學等方面進行了較全面的系統研究。

The vegetative tiller can produce more buds than the reproductive tiller on hordeum brevisubulatum population , and the age structure of bud from either vegetative tiller or reproductive tiller is an increasing model 野大麥種群營養蘗分蘗節的營養繁殖力比生殖蘗強,營養蘗和生殖蘗上芽的組成亦均為明顯的增長型年齡結構。
