Orchis robusta, Queen S´Albufera of Mallorca

Awesome, magnificent, splendid, beautiful in its purest form. Thus define the Orchis robusta, because that is the strong impression he made me see for the first time in their natural environment, standing water and mud of the Albufera of Mallorca. In a vast green carpet of sedges, reeds and buttercups, here and raise their heads above the long inflorescences proud pink orchid meadow. Oscillate in unison with lakeside vegetation swaying in the wind from the northeast like flowers floating on the waves of a green sea. His vivid shines and attracts like a magnet to lovers of nature from around the world only to see her and give her queenly feet.

Her large flowers and her great size differentiate it from the Orchis palustris. Both species bear a strong resemblance, so until recently orchidologist botanists saw it as a subspecies and gave the name of Orchis palustris subsp. robust. Worthwhile to expand the photo with a double click.

The Orchis robusta is a botanical rarity in Europe, as only live in the Albufera of Mallorca. The total number of copies is around 1200 feet. In the rest of the world can be found only in two localities in North Africa, Algeria and Morocco.

Impressive, right?. It is very difficult to understand the blindness and the absolute lack of sensitivity of some politicians, hoteliers and urban developers in Mallorca, unable to appreciate the treasure of this and other unique plants in the world. Its botanical and scientific importance is enormous, certified by top internationally renowned orchidologist, however, that should protect the contempt for them is nothing but a weed, a nuisance, vermin plant, an impediment to their business. If they were advised by professional real tourist would take into account the thousands of visitors who come to Mallorca just to see this orchid. Unfortunately his aides are not professionals and do not earn their pay and advise them bulldoze the habitat of the Orchis robusta, uprooting the few examples that barely survive surrounded by housing developments and hotels. Ecotourism is increasing in a world where nature in its purest state is increasingly scarce. Is a rising star. Be positive and trust that they open their eyes and be able to have vision. I would recommend dismissing his advisers.

While I made this picture to this pretty, two German couples lined up next to me to kneel before the queen of the Albufera and to pay homage. The photos that made him fly to his cold Germanic country jealously guarded as his best memory of Mallorca.

The Canarian banana: a tasty narcissistic triploid

Although the title may seem odd to you, in fact perfectly defines this giant grass. Its scientific name is Musa acuminata var. Dwarf Cavendish and is the result of a curious process of reproduction of a plant with itself followed by a dwarfing mutation. The delicious Canarian banana is thus a dwarf auto-hybrid..

Its original ancestor was an Asian wild banana, probably in the Indomalayan region, Musa acuminata, with a normal AA diploid chromosome and a fruit-filled chewy and inedible black seeds. A mutation in the germ cell of a flower disrupted the process of meiosis (which is usually divided by half the chromosome of the germ cells giving rise to haploid gametes A) and instead meiosis there was a mitosis. Plant genetic disorder is called Apomeiosis, ie absence of meiosis. As a result of this change a bunch of flowers of Musa acuminata mutant produced diploid ovules and pollen. Chance led to self-pollinate the flower with its own pollen and plantain seeds grew full of autotetraploid AAAA with two identical complete genomes, that is, the sum of AA genome diploid pollen and diploid AA genome of the ovule. 

Plant breeding this chromosomal aberration is perfectly viable, but often produce sterile plants. Many cultivated plants are polyploid (triploid, tetraploid, hexaploid, etc. ..), since its polyploidy them very effective and produce much larger fruits and tasty. An example is the bread wheat, Triticum aestivum, a hexaploid product of a spontaneous hybridization took place some 2,000 years ago, the grains are much larger than those of wild wheat. The giant strawberries and tomatoes are also polyploid. 

In animal and human genetics are also produced chromosomal aberrations polyploidy complete, but the embryos are not viable and die producing a spontaneous abortion. Sometimes the only surviving trisomies (Down syndrome, Edwards, Patau, Klinefelter, etc ...) and haploidy (Turner syndrome) in a single chromosome, but never complete polyploid.

After making a random wild banana seeds full of autotetraploid, one of the seeds germinated and gave rise to an embryo with four banana AAAA identical genomes. Again the chance was a native discovered the banana autotetraploid, whose bananas were bigger, with more pulp and seeds were not, being sterile. Not being able to reproduce by seed, turned to the division of its rhizome and thus was born the first planting Asian banana.

The new banana AAAA did not produce seeds, but their pollen is viable and fertilized a diploid flower of a wild Musa acuminata nearby forest. The result of this retro-hybridization was a banana with AAA triploid seeds. (Diploid pollen AA x Haploid ovule A = Triploid seeds AAA). 

Again fate played into the man and a hybrid seed germinated and gave rise to a triploid banana  with large, flavorful and seedless fruits, that they matured pathenocarpically without being fertilized. Had been born the Cavendish variety, the progenitor of the Canary banana.

In the Canary Islands were built huge rafts over the banana plantations so they could be watered by gravity without any pumping machinery. The banana trees are planted in terraced, following the topography of the volcanic slopes. Each farmer has owned a few hours per week of irrigation water with his own pipe connected to the community pond and a stopcock padlocked to prevent theft of water. The tangle of intersecting tubes is spectacular. "Acequiero" only able to know who owns each pipe and each lock. 

A spontaneous mutation in germinal meristem of a rhizome of the new Musa acuminata var. Cavendish banana resulted in a smaller, thicker stems, very productive, resistant to sub-cool winters, with high quality fruits, the dwarf banana Musa acuminata var. Dwarf Cavendish. Its hardiness and excellent qualities of his favored bananas growing and expanding all subtropical areas, including the Canary Islands, where he found an ideal climate for cultivation. 

The rhizome will produce shoots that grow to flowering and fruiting. Once the bananas have ripened, the stalk dies and is replaced by one or more new shoots. In the photo of a banana Tazacorte can see a cut stem which has already borne fruit, a stem that is bearing fruit and a small tiller that will replace it. 

The cluster of Canarian banana flowers of three types. The first 5 to 15 rows of female flowers are open and barren, very rich in nectar and ripe fruit by parthenocarpy without being fertilized. After opening several rows of hermaphrodite flowers and finally near the top of the bunch is fertile male flowers open. Banana farmers to avoid unnecessarily weaken the banana and at the same time reducing the enormous weight of cluster apical cut the hermaphrodite and male flowers and leave only the parthenocarpic female flowers. 

Parthenocarpic female flowers of the Canary banana her long, thick pistil surrounded by two white tepals: the upper is longer than the pistil and the shorter lower. These pistils are cut with a special knife with the intention of facilitating the fattening of the fruit and give a better look at the bananas at the time to market.

Large cluster of bananas from the Canary Islands with the apex and floral styles cut, ready to be collected for shipment to markets in the rest of Spain where they are greatly appreciated. They are usually harvested when they have not yet reached their peak of ripeness. This will facilitate transportation. Once they arrive at the markets and the homes of consumers end maturation in a few days.

Currently in the Canary Islands are grown other varieties adapted to subtropical climate, such as the Great Dwarf, and in recent years are experiencing the growing of two local teams called Brier and Gruesa.
In tropical countries, cultivated the call male plantain, Musa x paradisiaca, which produces large banana takes seedless pulp, unfit to be eaten fresh, but of excellent flavor when fried or baked. The plantain is a natural hybrid between Musa acuminata and Musa balbisiana.
In frost-free Mediterranean climates is grown the called garden banana, Musa x Orinoco, a hybrid able to withstand the cold winters of the coastal areas of the Mediterranean basin, where it rarely reaches freezing. 

  Ideally, the Musa x Orinoco is 4 meters high. To withstand the long, dry and hot summers of the Mediterranean requires abundant irrigation weekly. In winter, cold and wind burn their leaves, but when temperatures rise again in April re-sprout new leaves and blooms in midsummer with a small cluster of red flowers.

And to finish with good taste, here I put the recipe for a delicious dessert easy to prepare: 

Canary bananas fried with honey, sesame and pine nuts: 

A little butter or vegetal oil is put in a frying pan and the pine nuts are toasted. When they have taken a toasted color, the sesame is added and next a pair of spoonfuls of honey, lowering the fire to the minimum. Two or three bananas by person are peeled and add to the frying pan upon the other ingredients, to the three minutes return them and they are left other three minutes, always to sweet fire. They are delicious.
