本文根據th . mortensen ( 1928 - 1955 )海膽專著( amonographoftheechinoidea )中
的主要分類依據,將海膽綱分為8個目: 1 )頭帕目( cidaroidea )有齒器,圍肛部在頂系內,圍口部有步帶板和間步帶板,大棘很大,有外皮層,無球棘; 2 )鱗棘目( lepidocentroida )有齒器,圍肛部在頂系內,圍口部僅有步帶板,大棘不很大,無外皮層,有球棘; 3 )脊齒目( stirodonta )有齒器,圍肛部在頂系內,齒器
的齒有脊,橈骨片在齒上方不相接,顎孔開放; 4 )管齒目( aulodonta )齒器
的齒無脊,圍肛部在頂系內; 5 )拱齒目( camarodonta )有齒器,圍肛部在頂系內,齒器
的齒有脊,橈骨片在齒上方相接,顎孔封閉; 6 )全雕目( holectypoida )有齒器,但不發達或完全被吸收,圍肛部在頂系外,步帶不形成瓣狀和葉鰓; 7 ) ?形目( clypeasteroida )齒器發達,圍肛部在頂系外,步帶形成瓣狀,無葉鰓; 8 )
蝟團目( spatangoida )無齒器,圍肛部在頂系外,葉鰓發達,步帶形成瓣狀。

的比較
Scientists already knew that the creatures, which resemble underwater hedgehogs, are the only invertebrates ( animals without backbones ) on the human branch of the evolutionary tree
科學家們早就知道這種類似水底刺
蝟的生命是進化樹上人類這一分支中唯一

Morphology and cytology of intergeneric hybrids between hystrix duthiei ssp. longearistata and psathyrostachys huashanica poaceae : triticeae
長芒
蝟草與華山新麥草屬間雜種
的形態學和細胞學研究
In this paper, the whole process of it microsporogenesis and male gametophytes development was observed with microscope to sure weather stamen development is normal. at the same time, in order to provide techniques on biotechnology conservation and the foundation of its resources gene pool in cell engineering, its techniques on culture in vitro was studied
本論文通過對
蝟實小孢子發生和雄配子體發育全過程進行細胞觀察,探尋
蝟實
的雄性器官
的發育是否是
蝟實有性生殖
的薄弱環節,並對
蝟實
的離體培養進行了初步
的研究,為
蝟實生物技術保存、建立
蝟實種質資源基因庫提供細胞工程方面
的途徑和技術。
The hedgehog will hide its apples inside winchester and will construct hidden passages under the earth
蝟會把它
的蘋果收藏在溫徹斯特裏面,會建築隱藏
的地下通道。
The suitable culture medium of bud induction was ba4. 0 mg / l + naa0. 05mg / l, which had the suitable callus quantity and the rate of shoots differentiation was 21. 2 %
蝟實愈傷組織不定芽誘導
的最優激素組合為ba4 . 0mg l + naa0 . 05mg l ,其愈傷組織生長量適中,芽
的分化率達21 . 2 。
The results of stem culture were as follow : b5 medium had faster bud germination and low browning. when subculture medium was b5 + ba2mg / l + naa0. 2mg / l, the numbers of propagation were 3. 2 times of explants, what ' s more, the seedlings were robust
蝟實繼代培養基b _ 5 + ba2mg l + naa0 . 2mg l最為有利於
蝟實芽
的增殖,其芽
的增殖數為接種數
的3 . 2倍,小苗生長健壯。
The results of its culture in vitro were as follow : young leaves were the best explants in callus induction, the suitable culture medium was ms + ba2. 0mg / l + naa0. 1mg / l. the results of organ differentiation were that ba was better than zt in the induction of shoots, but zt was better than ba in the induction of root and callus quantity
蝟實愈傷組織誘導以幼嫩葉片為外植體較好,培養ms + ba2 . 0mg l + naa0 . 1mg l為好。進一步誘導器官分化,結果發現ba對芽
的誘導效應強于zt ,而zt在對根
的誘導、愈傷組織生長量上優于ba 。
By the time she had caught the flamingo and brought it back, the fight was over, and both the hedgehogs were out of sight : but it doesn t matter much, thought alice, as all the arches are gone from this side of the ground
等她捉住紅鶴回來,正在打架
的兩只刺
蝟都跑得無影無蹤了。愛麗絲想: 「這沒多大關系,因為這里
的球門都跑掉了。 」
Alice thought she had never seen such a curious croquet - ground in her life ; it was all ridges and furrows ; the balls were live hedgehogs, the mallets live flamingoes, and the soldiers had to double themselves up and to stand on their hands and feet, to make the arches
愛麗絲想,可還從來沒見過這樣奇怪
的槌球游戲呢?球場到處都是坎坷不平
的,槌球是活刺
蝟,槌球棒是活紅鶴紅鶴: phoenicopterus科,趾間有蹼,因種不同羽色各異,有紅灰等色。
A fish swim so light, swim into the heart of the hedgehog, broken the dream of the aquatic
