摘要通過野外調查和室內觀測對貴州省梵凈山樹附生尖葉擬船葉蘚種群的研究表明,其生境因其所附生的樹種不同而有所不同,但具有共同特點:附生在樹干下部距地面2m高的范圍之內,光照弱、濕度大、風速小、蒸發量小、中下部樹皮保持濕潤的持續時間長;其為雌雄異株蘚種,雌、雄器苞形態差異明顯,雌器苞數量多,雄器苞數量少並且難于發現,孢子體直立,蒴柄細長,孢蒴規則長卵形,蒴帽兜形。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
結果表明:林分郁閉度和光照條件顯著影響粗莖鱗毛蕨種群的株高、冠幅、葉片數量、葉片寬度、孢子葉數等形態指標。Like thallose liverworts, the hornworts have an alternation of generations in which the gametophyte is a dorsiventral flattened green phallus and the saprophyte is an upright structure that has a foot embedded in the gametophytes, from which it draws nutrition
與葉狀體植物地錢一樣,角苔具有明顯的世代交替, ,配子體在世代交替中占優勢,孢子體佔劣勢且利用其基足插入配子體的組織中吸取養料,以供孢子體生長。In vascular plants the diploid sporophyte is the dominant phase and in the ferns, for example, the gametophyte is a small prothallus

球果:孢子葉向中軸聚攏形成的結構,存在於裸子植物門植物、石松亞門植物(石松)和木賊綱植物中(楔葉類) 。Examples include male and female plants in dioecious species, aerial and submerged leaves, alternation of gametophyte and sporophyte stages of a life cycle, and mesophyll and bundle - sheath chloroplasts
例如在雌雄異株物種中的雌性植物和雄性植物,氣生的和被水浸沒的葉片,生活史中的配子體與孢子體的交替,葉肉和維管束鞘葉綠體等。In the clubmosses and horsetails only one type of strobilus is formed, while in the gymnosperms female megastrobili and male microstrobili both develop
