The extracting technology of fucoidan from sporophyll powder of sea mustard undaria pinnatifida suringar by enzymatic hydrolysis 热水浸提法提取裙带菜孢子叶粉岩藻聚糖硫酸酯的工艺研究
2.
A very small tongue - shaped flap of tissue inserted on the upper surface of the leaves ( microsporophylls ) and sporophylls of certain clubmosses ( e . g . selaginella ) and quillworts ( isoetes ) 某些石松门（如卷柏）和水韭类植物（水韭属）的孢子叶上具有的一种极小的舌状结构， 。
3.
The results of variance analysis showed the variant extent of above 5 morphologic characters was plant height > crown breadth > sporophyll number > leaf number > leaf breadth in turn 方差分析结果表明： 5个形态指标在种群间的差异程度依次为株高冠幅孢子叶数叶数叶宽。

Strobilus ( pl . strobili ) a group of sporophylls ( spore - bearing leaves ) arranged around a central axis , found in gymnosperms , lycophyta ( clubmosses ) , and sphenophyta ( horsetails ) 球果：孢子叶向中轴聚拢形成的结构，存在于裸子植物门植物、石松亚门植物（石松）和木贼纲植物中（楔叶类） 。
5.
The results showed that plant height , crown breadth , leaf number , leaf breadth and sporophyll number of dryopteris crassirhizoma populations were influenced by forest crown density and light condition 结果表明：林分郁闭度和光照条件显著影响粗茎鳞毛蕨种群的株高、冠幅、叶片数量、叶片宽度、孢子叶数等形态指标。
