玉树鹅观草主要生育期的化学计量特征OA北大核心CSTPCD
Stoichiometric characteristics of Roegneria yushuensis in different growth periods
研究植物的碳(C)、氮(N)、磷(P)化学计量特征对于评估植物的养分需求和养分供应状况具有重要意义,有利于揭示植物适应环境的生态策略.本研究测定了玉树鹅观草(Roegneria yushuensis)在花期、乳熟期、蜡熟期及完熟期的茎、叶、穗、根的C、N、P含量以及其化学计量特征和分配比,探究玉树鹅观草各功能构件C、N、P含量及其化学计量比的生育期变化规律,为玉树鹅观草的科学收获提供理论依据.研究结果显示:1)玉树鹅观草C、N、P含量均值分别为 …查看全部>>
Studying the stoichiometry of carbon(C),nitrogen(N),and phosphorus(P)in plants is of great significance for assessing their nutrient demand and supply status,which is beneficial to reveal their ecological strategies to adapt to the environment.This study measured the C,N,and P contents of stems,leaves,spikes,and roots of Roegneria yushuensis during the flowering,milk,dough,and mature stages,as well as its stoichiometric characteristics and allocation ratios.…查看全部>>
