VANILLA FROM AROUND THE WORLD
ABOUT VANILLA SPECIES
Porteres in Bouriquet (1954) describes 110 species of vanilla, distributed in the tropics of both the world and the New World. They belong to the orchid family, Orchidaceae, which is the largest family of flowering plants, with about 700 genera and 20,000 species. The Orchidaceae comprise a very natural, distinctive and highly advanced group of monocotyledons. They are perennial herbs which are widely distributed throughout the world with the greatest number in the tropics.
They exhibit a wide range of life form and have terrestrial, climbing, epiphytic and saprophytic species. Apart from the large number of ornamental species which are grown for the flowers, vanilla is the only genus which has species of economic importance.
The correct name of the commonly cultivated vanilla of commerce is Vanilla fragrans (Salisb) Ames, Syn V. planifolia Andrews, Epidendrum vanilla L. Myrobroma fragrans Salisb.
Two other species are occasionally cultivated, but yield an inferior product, they are:
V. pompana Schiede, West Indian Vanilla, which occurs wild in southeastern Mexico, Central America, Trinidad and northern South America. It is cultivated to a small extent in Guadeloupe, Martinique and Dominica. It resembles V. fragrans, but the leaves are larger, being 15 - 30 cm long and 5 – 12 cm wide. The greenish yellow flowers are larger and more fleshy, with perianth lobes up to 8.5 cm long. The lip has a tuft of intricate scales, instead of hairs in the center of the disc. The cylindrical pods are shorter and thicker, being 10 – 17.5 cm long and 2.4 – 3.3 cm in diameter.
V. tahitensis J.W. Moore, Tahitian vanilla, indigenous to Tahiti and cultivated there and in Hawaii. This species is less robust than V. Fragrans with more slender stems and narrower leaves which are 12 – 14 cm long and about 9 – 10 mm wide, tapering towards each end.
POLLINATION OF VANILLA
The flower is so constructed that self-pollination of the individual flower is impossible, unless hand-pollinated, due to the separation of the stamen from the stigma by the rostellum.
In Mexico and Central America, where vanilla is indigenous, some of the flowers are pollinated by bees of the genus Melapona. Nectaris secreted by the base of the lip and the flowers are sweet-scented. Hummingbirds have been observed visiting the flowers and it has been suggested that they may also be pollinating agents. Elsewhere, hand-pollination is carried out. In Puerto Rico, natural pollination was about 1 percent (Childers and Cibes, 1948). The method of hand-pollination was discovered by Morren in Liege in 1836, and Edmond Albius, a former slave in Reunion, discovered a practical method of artificial pollination in 1841, which is still used.
V. fragrans usually flowers only once a year over a period of about two months. In Mexico this is usually in April and May and in the Malagasy Republic, Reunion and the Comoros Islands between November and January. As already stated, the flowers open from the base of the raceme upwards and usually one, or more rarely two or three flowers are open on the inflorescence at one time.
The flowers open early in the morning; they are receptive for eight hours and wither the following day. Fruit-set is highest when pollination is done early on bright mornings following rain. If fertilization has been successfully achieved, the flowers remain on the rachis; if unsuccessful, the flowers drop off in two or three days. Thus it is possible to judge the number of fruits which have set and to discontinue pollination when the desired number have been obtained.
Hand-pollination is done with a splinter of bamboo or other material about the size of a toothpick. The flower is held in one hand and the labellum is pushed down with the thumb releasing the column.
The stamen cap is removed by the stick which is held in the other hand which exposes the pollinia. Then the flap-like rostellum is pushed up under the stamens with the stick and, by pressing with the thumb and finger, the pollinia are brought into contact with the sticky stigma to which the pollen mass adheres.
When fertile cross-pollinated seed is required, it is, of course necessary to obtain the pollinia from another plant.
Vanilla grows best under filtered sunlight.
It flourises well in partial shade that cuts out about 50% sunlight. Since it is a climbing vine, it requires support for growing. Dead wood posts, few species of Erythrina, Plumeria alba and Glyricida are suitable standards for trailing vines. The crop is established by planting in situ shoot cuttings of 60-100cm length. After pollination, a full length bean is attained in six weeks time which in turn takes 6 months to reach full maturity. Under reasonable levels of management , Vanilla yields about 500 gms of green beans and 150 gms cured beans per plant.
Our vanilla selction plants with the special technolgy produces flower in 12-18
month periods( special selections of vanilla plants).
The per plant yield will be around 500 gms average in the first year and
going upto 3 kgs per year per plant.
You can get the average of yields per acre( 2 Tons per year after 18 to
24 month period You save around 1 year of gestation period here and thereby
saving on finance costs).
We have developed a new method for the cultivation of vanilla in order to
get more yield as well as good prodcution of selective beans per node.
A one-metre long stem of vanilla is planted initially. After Three months, it starts sprouting from where it was adjusted.
Every month we adjust the plants for it s optimum growth in terms of its branches and apical dominance and therby control the plant growth to make it optimum for flowering.
After nine - twelve months, it starts flowering between the new growth and the point of incision.
After Next year, the second growth starts . It starts flowering and fruiting in bunches from all
the nodes .The plants start yielding within one/ two years depending on active biomass and growth achieved, bunches of pods spring up from many nodes of the same branch and 20 to 25 fruits are obtained from each bunch.
STRUCTURE
V. fragrans or vanilla planifolia is a fleshy, herbaceous perennial vine, climbing by means of adventitious roots up trees or other supports to a height of 10 – 15 meters. In cultivation it is trained to a height which will facilitate hand pollination and harvesting.
ROOTS
Long, whitish, aerial, adventitious roots, about 2 mm in diameter, are produced singly opposite the leaves and adhere firmly appressed to the support up which the plant climbs. The roots at the base ramify in the humus or mulch layer. An endotrophic mycorrhiza is present. The outer parchment-like sheath or velamen is rather poorly developed.
STEM
The long, cylindrical, monopodial stems are simple or branched, and are succulent, flexuouse and brittle. They are 1 – 2 cm in diameter and are dark green and photosynthetic with stomata. The internodes are 5 – 15 cm in length.
We offer vanilla planifolia variety of plants in sizes as below:
(1) Standard - 1ft vines- supplied bare & rooted.
(2)Medium - 2ft size vines - rooted and bare.
(3)Regular planting grade- 1 m vines - rooted and bare.
As an unique service to growers of vanilla planifolia around the world we have setup a huge nursery of quality production plants.We also offer tissue-cultured vanilla - as ex agar plants in 6 inches hardened plants.

Bourbon curing method: Bourbon vanilla is the name given to the product from the former French possessions in the Indian Ocean, which employ a curing technique first developed on the island of Reunion, formerly known as Bourbon. Production of Bourbon-type vanilla is now dominated by Madagascar, with the Comoro Islands and Reunion as smaller but important sources.
