進行裙帶菜配子體孤雌生殖、孤雄生殖和雌雄受精的再生途徑實驗，結果沒有得到孤雄生殖的裙帶菜，孤雌生殖的效率低、時間長且發育不正常，雌雄受精的再生途徑一個月左右90 %以上的雌配子體都正常萌發成幼孢子體。Length, diameter, density, fresh weight, dry weight, water content, osmotic potential and element concentrations ( ca, mg, na, k, cl ) were determined for each. seedling of b. gymnorrhiza and a. corniculatum were cultured for 60 days on various salinity of seawater ( 0, 5, 10, 15, 20, 30, 40, 50 ) in green house. samples were taken at 3, 7, 11, 15, 22, 30, 45 and 60 days after planting, separated into root, hypocotyl, stem and leaf
本文研究了福建九龍江口木欖和桐花樹胎生繁殖體從果實形成到發育成熟過程中形態、生物量、含水量、胚軸密度、滲透勢、五種主要礦質元素（ ca 、 mg 、 na 、 k 、 cl ）等的變化和溫室內人工鹽度梯度栽培下木欖和桐花樹成熟繁殖體長成幼苗（ 0 60d ）過程中形態、生物量、含水量、滲透勢、光合蒸騰特性、五種主要礦質元素（ ca 、 mg 、 na 、 k 、 cl ）等的變化；並且在野外自然條件下，跟蹤調查不同灘塗位置下秋茄成熟繁殖體定居成活、自然死亡狀況以及測定幼苗生長過程中（ 1年）形態、生物量、含水量、光合蒸騰特性等的變化。The callus was induced and proliferated using young leave as explant, which comes out at early spring. in this paper, the author discussed the induction effect and the proliferation effect by using different kinds of hormone and different physical - chemical factors
本文以山茶初春新生枝條的幼葉為外植體，採用不同的培養基，探討了不同的植物生長調節物質對愈傷組織的誘導和不同的理化因子對愈傷組織的增殖效應。After 1 year, the survival rates of seedlings planted in k. candel forest, avicennia marina forest and at bare tidal flat were 54. 7 %, 13. 7 % and 76. 0 %, respectively. insect and crab feeding were the main cause of lower survivorship of k. candel seedlings under a. marina forest. among the surviving k. candel seedlings, seedlings at bare tidal flat grew much better in terms of height, diameter, leaf production and biomass than did under the a. marina forest and k. candel forest
高鹽（ 30 % 0一50 % 0 ）影響桐花樹幼苗的萌發; o一30 % 0鹽度下桐花樹幼苗的凈光合速率、蒸騰速率和氣孔導度都表現為低鹽促進，高鹽抑制的變化趨勢;無鹽條件下幼苗的凈光合速率明顯低於5 ~加% 0鹽度:桐花樹胎生繁殖體脫離母樹后，在隨后的生長發育過程中表現為吸收累積鹽分的過程。Gonadal development and fecundity are affected by certain essential dietary nutrients, especially essential amino acids, essential fatty acids, and vitamins etc. thus, during the last two decades, more attention has been paid to the optimal level of different nutrients in broodstock diets. it is well known that protein is a kind of indispensable nutrient because of its important physiological function on body structure and supplying energy to the growth and development of shrimp and crab. protein and amino acids of broodstock diet have been identified as major dietary factors that determine successful reproduction and survival of offspring
而這些問題的解決則要求對中華絨螯蟹生殖過程中的攝食和消化生理機制，親體性成熟期對各種必需營養素（如必需氨基酸、必需脂肪酸和維生素等）的需求，卵細胞發生過程中營養物質的合成、轉運及貯存規律，以及在受精卵、胚胎和后續以內源性營養為主的?狀幼體發育階段對卵黃磷蛋白的消耗和利用模式等環節進行較為深入的研究，在全面系統地了解中華絨螯蟹的生殖營養生理的基礎上，探討親體生殖營養對卵質、孵化及后續幼體生長發育的影響。Crested ibis ( nipponia nippori ), a kind of peculiar wading bird in east asians facing its extinction because of humanbeings " economic activities. seven crested ibises found at yong county shaanxi province in 1981 were the all wild individuals left in the world then. to protect this rare bird, scholars have carried out a great deal of researches on it in many areas. however, till now, studies is mainly confined to some areas such as ecology and morphology, little was done in the area of molecular biology. phenomina such as disable individuals increasing and adults " producing ability decreasing occurred more frequent in recent years. these badly affected the existence and development of this species. so, getting the information about crested ibis " gene and genetic diversity through studies at molecular level and setting up scientific producing and protecting projections are becoming urgent tasks
為保護這?瀕危鳥類，我國學者對朱?展開了多方位的研究。然而迄今為止，這些研究主要限於生態學、形態學等方面，分子生物學領域則很少涉及。近年來朱?種群頻繁出現諸如殘疾幼鳥增多、成鳥繁殖力下降等問題，已嚴重影響到種群的生存與發展，因此，從分子水平對朱?進行研究，了解其基因信息和遺傳多樣性，並確定個體之間的親緣關系，從而制定科學、合理的繁殖計劃與保護對策，已成為當務之急。The bmn cells and fifth instars were infected by the recombinant virus bacpak - angiostatin. the bioactivity of the protein product was determined by human umbilical vein endothelial cells ( ecv304 ) growth assay in vitro and inhibition of vascular growth assay in cam in vivo. angiostatin showed significantly inhibitory effect on endothelial cells
