(1) Under different situations in nature Azolla is regarded to be an undesirable weed or a very beneficial plant.

(2) Wuhan Azolla school quite good.

(3) The ultrastructure of Azolla filiculoides was investigated by means of transmission and scanning electron microscopy .

(4) In a word, rice - duck azolla integrated farming is a safe and high efficiently ecological approach.

(5) This paper is to study the response of Azolla filiculoides Lamk in growth and physiology to different concentration of Pb and Hg.

(6) Albatron"s wife - Azolla, in order to search for love has been missed, willingly, leaving their families abandoned women;"

(7) The recent use of Azolla for phytoremediation is summarized in this article.

(8) Azolla filiformis could fix nitrogen, so further research should be made to find out if it can be used in waste water treatment.

(9) Azolla and Canna rapidly becoming the industry's well - known brands.

(10) The column filled with dried Azolla biomass was tried for sorption and recovery of some metal elements from electroplating effluent.

(11) Growing azolla raise the productive potentialities of paddy field[sentencedict.com], and further a virtuous circle of its ecological environment.

(12) Growing azolla has less effect on increasing the grain yield in present cropping season, however, azolla incorporated as manure the rice grain yield of present season increased by 5%.

(13) The "organic agriculture" which was risen in 1970s brought to a widespread attention on the investigation and utilization of Azolla .

(14) The article studied increasing yield and population dynamics of azolla in rice - duck azolla integrated farming.

(15) The results showed that illumination affected the growth rate and resistance of Azolla against black rot disease, both of which were lower under weak light (Tables 1,2).

(16) The methods here reported were suggested using to measure the ecological-physiology parameters of Azolla germplasms.

(17) In one, for example,[sentencedict.com] officials describe how to plant a fern called azolla in otherwise unusable wet spots; it can be used to make extra cattle feed that enables cows to give more milk.

(18) The results show, with increasing metal concentration, the growth of Azolla is inhibited, the content of chlorophyll decreases and the soluble proteins are affected in some degrees.

(19) Studies on the microstructure and ultrastructure of photosynthetic apparatuses in Azolla.

(20) The fish-raising sewage may be circularly reused after it is absorbed by Azolla and vegetables, as well as undergoing comprehensive treatment for water purification.
