胎生繁殖 meaning in English
viviparous reproduction
Examples
- This kind of viviparous reproduction allows rapid growth and establishment of mangrove seedlings once they come into contact with the substratum
这种胎生繁殖方法可增加红树在潮水涨退和不稳定泥土的环境里之生存机会 - 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
本文研究了福建九龙江口木榄和桐花树胎生繁殖体从果实形成到发育成熟过程中形态、生物量、含水量、胚轴密度、渗透势、五种主要矿质元素( ca 、 mg 、 na 、 k 、 cl )等的变化和温室内人工盐度梯度栽培下木榄和桐花树成熟繁殖体长成幼苗( 0 60d )过程中形态、生物量、含水量、渗透势、光合蒸腾特性、五种主要矿质元素( ca 、 mg 、 na 、 k 、 cl )等的变化；并且在野外自然条件下，跟踪调查不同滩涂位置下秋茄成熟繁殖体定居成活、自然死亡状况以及测定幼苗生长过程中( 1年)形态、生物量、含水量、光合蒸腾特性等的变化。 - 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
高盐( 30 % 0一50 % 0 )影响桐花树幼苗的萌发; o一30 % 0盐度下桐花树幼苗的净光合速率、蒸腾速率和气孔导度都表现为低盐促进，高盐抑制的变化趋势;无盐条件下幼苗的净光合速率明显低于5 ~加% 0盐度:桐花树胎生繁殖体脱离母树后，在随后的生长发育过程中表现为吸收累积盐分的过程。
