Una Flor que es un Bomba Fetida

Amorphophallus titanum, literalmente "falo amorfo titánico") es una planta herbácea, tuberosa que produce una inflorescencia en espádice llamada a veces "la flor más grande del mundo"; en mayo del 2003 la Universidad de Bonn (Alemania) presentó un ejemplar vivo de 2,74 m de altura.
Esta especie es originaria de las selvas tropicales de Sumatra (Indonesia), y además de su extraordinario tamaño, posee otra característica que la hace única: desprende un fétido olor a carne podrida, lo que impide estar cerca de ella por mucho tiempo. Es por lo que se la ha denominado "flor cadáver". La función de este desagradable aroma es la de atraer insectos para que se encarguen del intercambio de polen necesario para su reproducción; atrae moscas que buscan cadáveres en los que depositar sus huevos, de los que saldrán luego larvas saprófagas.

A. titanum es una hierba que puede superar los 3 m de altura. Tiene un tubérculo superficial, del cual brota un único tallo de hasta 1 m de largo, que a su vez presenta una única hoja y un pedúnculo floral. Su floración es un acontecimiento, pues sólo lo hace tres ó cuatro veces en los cuarenta años que suele vivir la planta. Una vez que comienza a aparecer la inflorescencia, crece a un ritmo de 10 cm al día hasta alcanzar un promedio de 2,50 m. de altura, aproximadamente 1 m de diámetro y un peso de 75 kg. Luego de esto, la flor solo vive durante 3 días.

Las flores forman una inflorescencia en forma de espádice, protegida por una espata (una bráctea acanalada, oval o elongada, de gran tamaño), verde por fuera y rojo intenso por dentro, que se abre al madurar formando una estructura acampanada en la base de la inflorescencia. La espádice es de color amarillo pálido, con las flores femeninas —reducidas a un pistilo— en la zona inferior y las masculinas en la superior; el ápice de la misma está compuesto por flores estériles, llamadas estaminoides. Para evitar la autopolinización, las flores masculinas se abren un día más tarde que las femeninas.

Carlos, es impresionante la flor cadáver, como para ponerla en el jardín de casa. Este año tuve la oportunidad de conoocer tu país y me dejó gratamente impresionado. Antes de salir, sólo voy a pedirte 20 segundos de tu vida para que accedas a mi blog http://www.hiperbreve.blogspot.com y leas alguna de mis pequeñas historias, voy muy bien en el certamen pero necesito el empujoncito final y ¡sólo faltan dos días!. Si en conciencia piensas que podría merecer tu voto, adelante. Si no, me basta con que me dejes un comentario sobre lo leído. Muchas gracias y disculpa la intromisión em la intimidad de tu blog.

Howdy

I just joined this good place. Loads of people have contributed so many good things here. Please accept my little contribution towards community. I would like to share some [url=http://www.weightrapidloss.com/lose-10-pounds-in-2-weeks-quick-weight-loss-tips]quick weight loss tips[/url]. If you need to know how to lose 10 lb in a week, you are believably not looking for a standard dieting and work out plan. You can lose weight with a general diet and workout plan, However this involves a lot of time doing intensive cardio workouts and sticking with a strict diet. Here I will draft the right steps that I took to lose 10 pounds in just a calendar week.

1. Stay away from all deep-fried foods for the week
2. Drink an 8oz glass of Citrus paradisi with breakfast every day. (this speeds up up your metabolism)
3. Eat fair portions (stop taking when you are full)
4. Instead of consuming 3 big a meals a day, eat up 5-6 small meals to keep your metabolism up and keep your body burning fat.
5. Do not eat anything after 9pm. When you eat that late your body does not burn off the calories.
6. Take proper sleep every night. Not taking adequate rest has been proven to be a ranking factor to the body storing excess fat.
7. Use a body/colon cleanse for the 7 days. This will get rid of extra weight stored just about the tummy area as well as cleanse your body of harmfull pollutants that cause you store fat and feel tired. Flush away excess pounds around the stomach area that otherwise would be hard to lose.
8. I suggest you using Acai Berry Diet Pills. This one is proven to work, and you can get a free trial.
9. For those individuals who want to burn fat quickly, avoid intoxicant.
10[url=http://www.weightrapidloss.com/lose-10-pounds-in-2-weeks-quick-weight-loss-tips].[/url] A low GI diet is an brilliant method of loosing weight quickly.

Thanks![url=http://www.weightrapidloss.com].[/url]!

[url=http://www.adidasforum.com/adidas-consortium-“runners”-pack-nicekicks-com/]Adidas Forum[/url]
Now here's a shoe-in for the list of the year's best gaming-related clothing : Adidas has brought back its ZX 5 hundred running shoe, and, since it originally comes from the '80s, the gaming electrified design and coloring is a simple choice ... Right? The kicks may not be the coolest part of the deal, either ; they come packaged with a combo bracelet/USB flashdrive containing ZX Runner, a computer game based primarily on ... The shoe itself.

GameCulture writes the game stars a personality named'DJ Zed' who, according to Adidas, has five mins to'run, moon-walk, climb walls, avoid some dodgy-looking thugs, collect power-ups, and pull off loony rooftop-to-rooftop stunts' to get on-stage before his set starts. It looks suitably retro -- see for yourself in the video we've included after the breakdance.

This might be a bit off-topic but I believe there are a lot of smokers here on www.blogger.com. I have recently decided to find a good manufacturer of electronic cigarettes. I'm done with paying so much for tobacco smokes.A friend recommended [url=http://www.insanereleases.info/greensmokef.html]G Smoke[/url] According to their website this is how they described their product:
"Green Smoke offers supreme Electronic cigarettes with spendable cartridges that compose of the highest smoke volume in the industry. With a collection of flavors and nicotine levels, Green Smoke's™ patented technology offers convenience and performance that is unmatched. G Smoke products have been independently tested for safety."
I'm thinking of buying them. Anyone else have experience with this e-cigarette?
