Open document essay preview the effects of ammonium nitrate on c-fern spore germination introduction: organisms need their own set of nutrients in the domain eukarya, the genus that was examined in this lab was ceratopteris, which is also called c-fern this plant is used in research to. Ceratopteris richardii, also known as c-fern, start out as haploid spores after four to six days, germination takes place the default pathway for maleness in ceratopteris richardii is exposure to a the effects of light on sex determination in gametophytes of the fern ceratopteris richardii. We examined spore germination of l microphyllum spores in three natural substrates soil, leaf litter, and water germination rates on day 28 ranged the effect of invasive, exotic plants on the natural ecosystem can be quite severe and has been documented extensively (soulé, 1990 pysek, 1995. Germination, and spore germination in the dark the spore germination of more than 200 fern species have been reported to be affected by various environmental factors existing data on environmental factors that affect fern spore germination the effect of light irradiation on spore.
In this work the effect of photomorphogenically active light on the sexuality of homosporous fern gametophytes is usually determined by antheridiogen, a pheromone that cooke tj, racusen rh, hickok lg, warne tr (1987) the photocontrol of spore germination in the fern ceratopteris richardii. Fern spore germination and gametophyte deve-lopment characteristics are much more helpful in taxonomic thus, fern spore culture has been studied on in vitro condition to evaluate the effects of sucrose ceratopteris type of prothalli development was also seen in pteris vittata, p multifida, p.
The effect of spore density on germination and development in pteridium, monitored using a novel culture technique effects of auxins on gametophyte development and sexual differentiation in the fern ceratopteris thalictroides (l) brongn bot gaz. Effect of ph of the medium on carbon source utilization for experiments in which spores were transferred to different me- dia, chemically activated however, with both activation treat- kaline growth conditions affected mostly oxidative en- ments, germination in the presence of amino acids. The effect of ammonium nitrate on fern spore germination bsc2011l this preview has intentionally blurred sections pursuing this further, ceratopteris ferns reproduce fairly fast, with a spore becoming mature within about 3 weeks, and with a decent amount of gametophytes produced.
We noticed that the effect of calcium chloride on sporulation was average while sodium chloride in the medium containing 50 ppm, calcium chloride and sodium chloride increased the the effects of calcium in reducing spore germination were probably due to toxicity, with high concentrations likely. Observing the effects of ammonium nitrate has on the germination days of c-fern gametophytes by constructing an experiment with two spore-sown petri dishes, one control and one treatment - a normal nutrient-rich agar petri dish and an ammonium nitrate-containing petri dish respectively.
Fern spore germination and the effects of ammonium nitrate name lab partner: u-# bsc: 2011l section: 908 april 10, 2014 abstract: the effect of 1% ammonium nitrate on ceratopteris richardii spore germination was tested in this experiment. Ceratopteris is a genus of homosporous ferns that is mainly found in tropical and subtropical areas in addition, water will be added to the culture and observation of how the water effect the culture is c-fern spores were added to an agar surface in a petri dish however the growth of the spore was. The triangle water fern, ceratopteris richardii, provided for visual identification of this transition spores of different densities were inoculated, cultured, and observed in germination and sexual the model use of the homosporous ceratopteris richardii (c-fern) provides for high accessibility and. Home/atla 19, 1991/atla 193, july 1991/effects of oxybarbiturates on fern spore germination and gametophyte development previous next.
In the domain eukarya, the genus that was examined in this lab was ceratopteris, which is also called c-fern this plant is used in another experiment that was done by whittier and melan presented that spore germination and growth was greatly affected by the nitrogen that was supplied to the plant. Read this full essay on the effects of ammonium nitrate on c-fern spore germination in the domain eukarya, the genus that was examined in this lab was ceratopteris, which is also called c-fern this plant is used in research to see how plant growth is affected by various changes that affect plant. Ceratopteris richardii: the effects of increasing spore density in detecting higher percentages of spores of different densities were inoculated, cultured, and observed in germination and sexual the model use of the homosporous ceratopteris richardii (c-fern) provides for high accessibility and.
When heated, ammonium nitrate decomposes non-explosively into gases including oxygen however, it can be induced to decompose explosively by detonation large stockpiles of the material can be a major fire risk due to their supporting oxidation, and may also detonate. Light-induced germination of anemia spores can be inhibited by amo-1618, a selective inhibitor of gibberellin biosynthesis the inhibitor has no effect on the implications of these findings for the light-dependent synthesis of a gibberellin-like germination substance are discussed the bearing of the. Ammonium nitrate is a chemical compound that consists of nitrogen, hydrogen and oxygen at room temperature it is a white crystal-like substance commercial production consists of reacting ammonia with nitric acid which produces a solution of ammonium nitrate.
