在河北省承德市鱼儿山牧场中国农业大学科技攻关实验站 ,以生长二年的老芒麦为试验材料 ,研究不同生长时期老芒麦植株幼穗的分化规律。试验结果表明 ,老芒麦幼穗分化过程中茎尖生长锥出现一系列的形态变化 ,并根据分化的特征将其分为初生期、伸长期、结节期、二棱期、小穗突起期、颖片突起期、小花突起期和雌雄蕊形成期 8个时期
In order to study the differentiation of young spikelets of Elymus sibiricus in different growth stages, the two-year-old Elymus sibiricus was used as experimental material in the Scientific Research Station of China Agricultural University in Yueshan Mountain Ranch, Chengde City, Hebei Province. The results showed that there were a series of morphological changes in shoot apices during the spikelet differentiation process of Euglena simappo, which were divided into three stages: newborn period, elongate stage, nodular stage, , Glume protuberance, floret protuberance and formation of stamens in 8 periods
