Reproductive biology of Elymus scabrifolius (Döll) J. H. Hunz. (Poaceae: Triticeae), an important phytogenetic resource for saline environments

Ten plants per population (Table 1) were observed (n = 10 plants per population) twice a week. To obtain the number of flowering days per population, for each plant, the date of the beginning of flowering (when the first spike presented at least one open floret) and the date of the end of flowering (when the last flowering spike presented more than 50% open florets) were recorded.

对每个种群（见表1）的十株植物进行了观察（每种群10株植物），每周观测两次。为获取每个种群的开花天数，记录了每株植物的开花起始日期（首次出现至少一个开放的花蕾的穗尖）以及开花结束日期（最后一个开花穗尖开放的花蕾超过50%）。
