Some parameters for the agamogenesis of Egeria najas were studied.
研究了不同梯度浓度的Hg2+对细叶蜈蚣草营养繁殖的影响。
The results indicae that the dominant species is Potamogeton malaianus Miq in the six aquatic plants with maximum fresh unit biomass of 6131 g/m^2, accounting for 61.59% of the total sample; The sub-dominant species is Egeria densa Pianch with maximum fresh unit biomass 3716 g/m^2, accounting for 24.78% of the total sample.
测定结果表明：在采集到的6种水草中竹叶眼子菜为优势种群，单位生物量最高为6131 g/平方公尺，占全部样本总量的61.59%；水蕴草为次优势种群，单位生物量最高为3716 g/平方公尺，占全部样本总量的24.78%。
Effects of Hg2 on agamogenesis of Egeria najasWhen Hg concentration was above 1.50mg/L, leaf of shoot fragment faded severely, compared to the control even the sprout also faded much.
Hg2 浓度l 。oom留L实验组中的侧枝新芽长度随着Hg2 浓度的增加而缩短，平均新芽长度在】。ocm以下。
The effect of gamogenesis, chlorophyll, superoxide dismutase and catalase of Egeria najas by different concentrations of suspended silt was studied.
研究了悬沙对细叶蜈蚣草营养生殖、叶绿素、抗氧化酶(超氧化物歧化酶和过氧化氢酶)等影响。
Fast growing species such as hornwort or waterweed remove nitrogen-containing pollutants from the moment they are planted.
生长快速的植物，诸如金鱼藻（Ceratophyllum demersum或伊乐藻(Elodea和Egeria)，一经栽种就能清除含氮的污染物。
When Egeria writes of ceremonies held on the Octave of Easter she is not clear. While, throughout the eight days, the Lazarium was decorated and adorned like for the Octave of the Epiphany, the ceremony of the fifth day took place, not at Bethany, but at the Anastasis. Thus, there is no sure proof that a special assembly took place at Bethany during the Octave of Easter.
当时，Egeria并不清楚她所描写的是复活节八日庆的礼仪，因为，整整八天，拉匝禄被装饰的像是为了主显节八日庆，庆祝活动在第五天举行，但地点不是在伯达尼，而是复活之地，因此，没有证据证明复活节八日庆期间有特别的庆祝活动是在伯达尼举行。
In the 9-10th centuries, the Procession of Palms which, in Egeria's time, had set out from Mount Olivet, started from Bethany itself. From there an olive branch was carried to the Anastasis in the Holy Sepulchre basilica.
在9到10世纪，Egeria时期，从橄榄山出发的圣枝游行队伍由伯达尼出发，有一队则往圣墓大教堂的复活之地前进。
Aquatic plant with deep green foliage useful as an aquarium oxygenator; sometimes placed in genus Egeria.
具有深绿色叶子的水生植物，通常被用作一种鱼缸的充氧植物。
This study tried to select potentially the most aggressive species in hope of facilitating the making and the assessment of future conservation strategies. They include terrestrial species of Bidens pilosa var. radiata, Imperata cylindrical var. major, Brachiaria mutica, Paspalum distichum, Leucaena leucocephala and aquatic species of Egeria densa, Myriophyllum aqualicum, Eichhornia crassipes, Pistia stratiotes, Alternanthera philoxeroides.
本研究提出最具入侵潜力的外来植物，以作为未来保育策略之评估指标，主要有大花咸丰草、白茅、巴拉草、双穗雀稗、银合欢、水蕴草、粉绿狐尾藻、布袋莲、大萍、空心莲子草等。
